I have a CZ 550 American with Kevlar stock in6.5x55. I believe the barrel is a hair under24 inches. It shoots really well.

Am bored and am Thinking of a rebuild. Would like to get a liitle more range and FPS for open country shooting.

Any suggestions?

Depends on how many more FPS you want to gain...

Well... A 264 wouldn't quite get to shine with that length bbl, but you'd still see a good gain in velocity.

Seems that a 140 AMAX in your x55 may wake up its LR potential, if it'll stabilize them.

Know would be better with a 26 inch barrel.

looking to get an extra 200 to 300fps.

Have tried the 140's and shoot ok. Looking to get a bit more.

I'm thinking rebarrel.

Guess the next thing you need to ask yourself now that you've established that you want a 200fps-300fps increase over what your 6.5 x 55 will do is, "How far am I planning on shooting in this open country..?"

Out to 500 to 600 yds on targets.

No farther than 500 yds on game . Depending how it shoots and practice time.


maybe a 6.5 x 284 with a rebarrel?

Your x55 will be fine at that range.

Ha ha ha... Ribka, I understand being "...bored and thinking.."

And I would submit that it is indeed the boredom and not the ballistics of your fine 6.5 x 55 that is driving this "thinking."

Tanner is right, and well... you probably already know that your 6.5 x 55 is capable within those ranges.

But, don''t let that stop ya... Maybe it's time for a new build..?

Personally I think that your diameter/caliber of choice is very cool, .264" bullets sure like to perform.

Loaded at equal pressures, I don't think that you can reasonably expect to gain 200 to 300 fps with an additional 9 grains of case capacity, 57 for the 6.5x55 vs. 66 for the 6.5-284.

If you set the barrel back a little and reamed the chamber to 6.5-06AI, you'd get around 73+/- grains of case capacity. Even with about a 16 grain increase in case capacity, you'd still be 9 grains short of the 264 Win Mag's capacity.

Jeff

I should spend my time fixing the sink in the bathroom according to my wife instead of thinking of gun projects.

Yeh, the 6.5x55 shoots so well and predictable that it is boring. Recoil is about the same as my .223

I just picked up a pre 64 .264 Westerner from a friend. Just too pretty to take out hunting

I think you've got two great 6.5s right there. That x55 sounds nice , and you also own a gun that resides in my dreams in that pre64 264. Hunt that thing, it'd be a crime not to. Or send it out to Colorado and I'll christen it on a big fat mule deer.

Ah sinks come and go...

Again, Tanner is right.

Now, an option would be to drop that 264 Westerner into a McMillan and and run it like it was meant to be.

I don't think I could keep a 264 Winchester in the safe and out of the hunt.

Have you thought about using the Berger 130 gr VLD and loading up to "modern" pressures in your 6.5x55? With that bullet started at 2800+ fps, wind would be your only issue in going out to 600 yards for hunting, and wind is less of a problem with that bullet in a modern-loaded 6.5x55 than a lot of the less aerodynamic bullets in a much faster cartridge.

Here are some numbers for 1000 ft elevation, 10 mph crosswind, and 2800 fps muzzle velocity:
velocity and wind drift @ 400 yds: 2180 fps, 10.1" wind drift
velocity and wind drift @ 500 yds: 2040 fps, 16.3" wind drift

A. the 264 uses a different bolt face.

B. The 140 out of a 'Swede is slowwwwwww.

Just hold tight,it's cabin fever,it will pass....don't mess up the Swede...

If you must molest a Swede, maybe an AI.

I just assumed that a 264 or 6.5x284 would be the rechamber he was talking about, boltfaces notwithstanding, but I do always overlook the damn bolt faces

In that action, don't you think you could run a 140 up to 260 speeds?

One thing you need to remember, ballistic coefficient doesn't really mean squat until significant longer range. BC only defines how much better the bullet resists shedding velocity. When you start the bullet slow to begin with, BC doesn't help you much.

The 'swede shooting a 140gr bullet, is probably a 2500-2600fps load.

Just my current view on the matter is to spend the money on reloading components and optic upgrades rather than messing with a rifle that already shoots good. I have 1000 bullets, a keg of powder and 5000 primers arriving tomorrow. I will order more when that is gone. When I wear out my current barrels then I will upgrade.

With the 6.5x55 you have Lapua and Norma brass available and a whole slew of high BC bullets to test. Lots of recoil is not going to encourage lots of practice and you should be able to get to 600 yards without the bullets bouncing off even if you use the SAAMI limit low pressure data and start them "slowww"...

http://www.lapua.com/en/products/sport-shooting/centerfire-rifle/18#tables A 123 Scenar at 3000 is not terrible slow.

6.5-257 Bob Imp.

maybe my Tikka 'swede is slow, but I didn't hit 3000 until I dropped to 100gr bullets. I believe a 123 Scenar is a probably a good choice regardless though.

Why would anyone not be happy with a 6.5x55 ? Been killing big game since 1894, still works just fine and, in a modern rifle, will exceed the 260 Rem that was everyone's darling just a few years ago.

The one on top is a R.F. Sedgeley (probably one of one) in 6.55x55 built on an 03 NM action. With the period correct 160 grain throat, longer action...... well it's just amazing with 140 Bergers seated way beyond SAAMI OAL specs.



The bottom one is a 22-06 but that's another story.

I'm thinking the 6.5-06, AI or reg, would be an easy rechamber and would give you more oomph.

I too would like a 6.5-06. My Swede is a nice shooter, but not really a long-ranger.

Would a Leupold with turrets and a good laser rangefinder make the 6.5x55 a dependable 500 yard hunting rifle with the proper projectile?

What do the long range shooters call it? Dialing for distance?

Jeff

Most respected big game hunter/authors would suggest that hunting anything other than varmints at 500 yards introduces a high element of chance. Certainly a 6.5x55 would kill at that range (the rifle shown above will put 10 in a Nickle @ 100 yards) but game moves, winds shift, mirage is misread, the shooter makes an error: any of which could produce a wounded animal and a hunt with bad memories. IME, in 55 years of hunting, you cannot really get too close, regardless of the weapon. The shot is an anticlimax compared to the hunt. I currently have a build underway for a 2000 yard 333 RUM "gong ringer" but shooting a big game animal with it would, IMO, not hunting. I've been in on too many recovery efforts for deer, antelope and elk that would have been unnecessary had the hunter halved the distance to the animal.
Good hunting !

You must not have heard of John Burns.

Actually, I thought that since you generally refer to me in unkind terms, you would have put me on "ignore" by now. If you haven't, you should.

Jeff

Jeff, may I refer you to a recent thread ? Perhaps after you read it, you will understand why you are not on ignore and will hear no more unkind words from me.

https://www.24hourcampfire.com/ubbthread..._Where_is_everybody_Less_par#Post6227461

As MLK said:" Hate cannot drive out hate: only love can do that."

John Burns may be a great shot and made some record kills.
John also has a direct financial interest in the results of the success of his weapons.

Very few who try are as good as he is and lose many animals. It's like Marine Sniper school, many apply, few pass. Sad for our big game, hunters do not have to undergo training like that.(As they do in Norway) "To obtain a hunting license, the applicant must complete a 30 hour, 9 session course and pass a written multiple choice exam. The course includes firearm theory, firearm training, wildlife theory, and environmental protection training."

I prefer the stalk to the shot.

Thanks.

It's all about choice and doing something "else" or "new" or "Different".

Necking down a 7mm WSM would give you a nice increase in velo very simply. It's a simple matter to adjust the bolthead for the slightly larger case head and the WSM would give you about equal case volume as the 264 Win.

Just because there isn't anything wrong with the Swede doesn't mean you can't improve on it.

I have two Gustav M96 Swedes, one with the OEM long barrel and one cut down to 20"...the "longtom' has the original ladder military sights and the Carbine has a Williams receiver sight. I have little trouble keeping 5 rounds in a 14" pizza box at 500 yds with 120-140gr handloads even with my old, bad eyes.

I probably wouldn't rechamber tho'. If I wanted a larger case and more velo I would probably trade off/swap/buy a long action rifle in 264 Win with at least a 26 and preferably a 28" bbl.

Larry,

You can write all the nice words you want, but just as Jacob Marley forged his chain, you've forged your reputation, link by link and yard by yard. Perhaps you can go back to MLK and see what he suggests for driving out contemptuous indifference?

Jeff

Ding, Ding, Ding .. we have a winner! No need for the AI.


but you knew I'd say that.

The swede is a fine cartridge!

The 264 winny will out run the 6.5-06.

If you build a "tweener" I guess you have the bases covered.

The only advantages the 6.5-06 have over the swede and the 264 winny are:

More umph with heavy bullets and flatter shooting over the swede.

Powder saver and barrel saver over the 264 win.

I recommended the 6.5-06AI for its physical dimensions and lengthened case life as much as for its increased case capacity. I do know that if you set a 6.5x55 back a couple full turns, depending of course on the thread specs of the action in question, a 6.5-06AI finish reamer will totally remove an existing 6.5x55 chamber. I don't know if a standard 6.5-06 finish reamer will do the same, because I have not done it.

Jeff

Not exactly what is being discussed, but I had this picture and thought I would share it for reference. L to R, 257 Wby, 6.5x55 and 6.5x280AI.

That 6.5-280 A.I. sure do look good...

Jeff, if you wish to continue to be a negative person, that is up to you. I have chosen the path elucidated on the thread I suggested you read.

The only "open item" on my agenda os Bricktop's $10,000.00 bet. Once that is settled ( I think we all know how) there are no more "issues".

Marley was a money changer, a profession hated in Dicken's anti-semetic England (although Dicken's did not play that card). I hardly fit the profile. Most folk who really know me would liken me more to Mr. Fezziwig.

More on point in describing our relationship than The Christmas Carol, would be The Mystery of Edwin Drood. I'll leave it to you to ascertain why.

May the Lord's blessings fall upon you and those you love.

We have no relationship, but with regard to Drood, what character do you see yourself as? Durdles, the drunken grave digger?

Jeff

Me too. I just love stalking ...

Fishhead, It will be an interesting test of the adults on the site (99.999%) to see which approach to dealing with your fellow members is more supported.

No, Jeff, I was referencing the fact that book was unfinished, as is our relationship.

You each are both living under a false premise. that your insults, name calling, thread pirating and other "uncivil" behavior will engender any reaction other than forgiveness.

Sorry, but the "troll wars" are over. The adults have won and your uncivil behavior is about as relevant to the conversations and business dealing conducted on the site as the number of angels who can dance on the head of a pin.

Have you read the thread I suggested yet ? Think the jury is in, case closed.

"Mustering up genuine compassion for those who have wronged us, instead of allowing anger toward them to eat away at us, is the course of action recommended by most psychologists." Sounds like a plan to me.

May the Lord's blessings fall upon you and those you love.

Who is posting under the handle "Internthem", Larry or Roger?

This DID, Dissociative Identity Disorder, formerly known in the trade as "multiple personality disorder", thing that you have going on really has me confused. Are you on your meds when you are Roger, who seems like a reasonable fellow, or on your meds when you are Larry, who is not a nice person?

Base on his past behavior, I find it difficult to believe that the "Larry" personality would ever be able to sincerely wish GOD's blessings on anyone, but when the words come from the "Roger" personality, they seem sincere.

Jeff

Jeff, as all the members of our club are able to use any of our dozens of user I.D.s, I guess that will remain a mystery.

I'm sorry you are confused, we'll include you in our prayers in the hope of healing you.

What you "believe" is really immaterial as you do not "know".

May the Lord's blessings fall upon you and those you love.

Guess a leopard can't change his spots...

Larry...

Is that the first picture of yourself you have ever posted ? Your name is ?

Larry too has a beard but is not as "well built".



May the Lord's blessings fall upon you and those you love.

I just had to put this in quotes for all to see.


You're not sorry. You continue to lie and deceive the owner of this forum with regards to the identities behind interthem and the dozens of other user I.D's. It's all a big game that allows Larry to continue to post and hide anonymously behind others.

There are very good reasons why he's been banned from this site multiple times. He's not an honorable man and neither are you. Mentioning prayers "in the hope of healing" is reprehensible considering the confusion arises from deceit.

Shame on you. You're the one in need of healing.



Strike two.

May the good Lord drive the hate and bitterness from your heart.
At our Sunday Internet gathering we will all pray for you to be healed.

I am still waiting for Larry to list all of his aliases on this thread....

https://www.24hourcampfire.com/ubbth...ere_is_everybody_Less_partic#Post6236043

if he has truly reformed, he will list all his usernames under which he has posted to clear the slate

if not it will be business as usual for him.

Odd how many guys in prison "truly reform" when they are in front of the parole board...get released and go do something else heinous...


If Larry does conduct business as usual, does this mean we can put stuff on layaway again with monopoly money???

Do you know of any group of people who share a user name on this site, or any message board like this, EXCEPT LARRY AND HIS "FRIENDS"?

I don't.

Why would anyone share a user name?

Why would anyone need multiple user names unless he/she was trying to hide something?

Why would anyone tempt fate and invoke the name of GOD in an insincere manner?

Why would anyone want to buy anything from a guy with such a bad record EXCEPT with Monopoly $$?

Jeff
