Home Forums Hunting & Shooting Hunting Rifles Montana 243 VS 7mm-08?

223 or 308 if you don't Reload. A schitty Colt Krunchenticker ain't even in the same book,let alone page...as a Montucky 223.

Now as the 243 vs 7-08 goes,in said platform...you is Hungchow in several ways. The 243 is 1-10" which sucks heavy ass and the 7-08 has more throat than box,though are twisted with enough RPM to do it all(which means 162's). I'd rather leap a 162,than kiss a Ping Pong Ball in the 243.

The 223 Montucky will be shot a whole [bleep] bunch more than anything else and along with the actual act of shooting,there is a byproduct of non-lineal "luck" that reliably begins to blossom.

Hint.

Now will a 223,243,7-08 and 308 shoot nice Agg's? Yes and reliably. Reliabler yet,is the dot connection of trigger time bolstering the daintytitude of relative Agg sizing. Conjoin light done right,in a handy/dandy parcel that is funner than [bleep] to shot and there will be a long line of patrons eagerly awaiting their turn. Good boolits,in good places...do great thangs.

Funny how it actually works.

Re-hint.

I'd go 7-08. .243 will be fine for whitetails but life MAY be more than whitetails tomorrow. 7-08 is more versatile, recoil will be minimally more but added bullet weight is often appreciated. Here we have a collection of 7-08's, wife's Dakota, son-in law's Browning, 2 Remingtons for my daughter and self in long guns and one pistol. Shot everything from prairie poodles to elk, kudu and caribou, lost count on deer (assorted) and pronghorns. Reloading is a snap and 7mm bullets are offered in nearly any size and shape (110-175 grains for sure) but factory stuff is available and as good as it gets. Still in doubt flip a coin.

Lightweight, Alabama Whitetails, and kids mean 243... especially in a rifle as light as the Kimber.

I've had at least 4 or 5 10-twist 243's... they work just fine. In an ideal world, a 9-twist is better, but in a world full of 6mm bullets it's pole vaulting mouse turds to fret over a 10-twist.

Best Regards...

B-, ironic you mention this now, good timing. I'm looking at picking one up this weekend that supposedly won't shoot for my nephews to try to burn out the barrel for exactly the reason you state. Hopefully it doesn't shoot as well as the 308 I picked up that wouldn't shoot.

Any particular load combos you recommend, assuming components are findable?

given you wife will hunt it the .243! For the 7-08 I would go .308 as easily the most simple to load and shoot, I find the 308 easy get to shoot accurately and it comes in those big green boxes of 500 rounds per...

its too bad you don't reload the .257 Roberts I have in select classic is a wonderful rifle, (but I know nothing as its a short action and everyone knows they are awful with 100 at only 3000 FPS) but I would take a Montana in same any day.

Better to just buy a 375 H&H, because life MAY include a cape buffalo hunt someday. It's more versatile than the 7mm-08, so that makes it better.

"I'd rather leap a 162,than kiss a Ping Pong Ball in the 243"
I still don't know what you mean by that statement and I've read it several times. Do you mean the 243 is too light? If so how is the 223 a better choice? I'm talking a Whitetail only rifle and 200 yards is a long shot around here. I'm sure the 308 is extremely versatile but recoil is a consideration.

It means the twist is [bleep].

What ballistic coefficient do you recommend for a .243?
(for hunting purposes)


+.500?

I don't recommend according to BC. I do know that my favorite don't work in a 1-10" twist and I have a bushel full of those.

Guess I'm curious as to what the upside of a 1-10" twist is?

That may be but since my maximum distance would be 300 yards, do I really need to be concerned with high BC bullets? I mean wouldn't I be more likely to get an accurate load being able to kiss the lands, or is the point that those bullets that will kiss won't stabilize with the 1 in 10 twist?

Trying to learn something here.

He would rather shoot high BC 162 AMAX's in a 7mm-08 than low BC bullets in the 243. 243 has good bullets available, but the slow twist on the 243 Montana won't stabilize them. Accurate, high BC bullets will perform better for you than low BC bullets that kiss the rifling. If you are bound and determined to shoot low BC bullets out of a Montana, you may as well go down to the 223 - you'll burn 1/2 the powder and the recoil is so light it will encourage a lot of shooting. Lots of shooting is more important than chambering, BC, etc....

What do you mean by "high BC bullets will perform better" Do you mean be more accurate at 200 yard range or just that they will hold their energy and not drop as much at long range? Keep in mind that a 200 yard shot is a very long one where I hunt. I'm just wondering if the low BC but heavier bullet of the 243 won't be a better killer at the shorter range.

There's no downside when you're out hunting with one.

.500 = 105?

.420 = 90 Scenar. Which works in a 10".


.080 BC makes or breaks what?

Shooting steel at 800 yards?


I fail to see a problem.









Doesn't sound like a sniper rifle is required.

You don't wanna be seating into the lands with a hunting load.

Titty Shooter,

May have more than (1) rifle myself and in mebbe more than (1) chambering.

Boolit weight means dick.

Hint.










Brad,

You poor,poor stupid [bleep].

Bless your heart,that you're still [bleep] tryin'.

Laffin'!










'bird,

My first pitch would be a 75A-Max kiss,in front of '335,with 400 fueled R/P hulls.

I hear good thangs.










'mmyp,

Do tell about how a 243 and 7-08 are "tough" to load for. Laffin'!

Please consider Whining a leetle louder,a leetle longer and leetle more often about your Do Nothing Bob.

It's a [bleep] hoot!











'Clark,

Grab a 223 Montucky and let everyone take a turn,then get back to me.

300yds ain't nearly far enough away,to be "fair".

Hint.










SammO,

The upside to a 9" 6mm,is that there is no downside. You can go .547 BC in 105,if'n you wish...though in fairness I'm smitten with .530 Fueled Forays.

Cheer up,it ain't like I ain't suffered 1-10" and 12" 6mm's.

Hint.










'goat,

Too bad I cain't recall the 100's of 1000's of kisses I've happily launched.

Hell...I reckon I may even toted a smooch on a Hunt.

Hint.

This schit do get funny and fast.

Boxer
What would be your bullet of choice for the 9 twist 223? Please give a second in case the first doesn't do well.

'Clark,

Sloooowwwwwww things down,skin 'er back and read everything I said again. It's all there.

Then thank me later.

A couple thoughts

Nosler manual #7
243 Winchester, 100 gr. Partition (similar to typical cup and core in ballistic co-efficient)
BC: .384
MV, 2900 FPS
200 yd. zero 1.7� high @ 100 yds., 7.3� low at 300.
7mm-08, 140 gr. Accubond (my favorite in the 7mm-08)
BC:.485

200 yd. zero, 1.8� high @ 100 yds., 7.7� low at 300.. I�
I don�t know how the terrain is in your part of Alabama, but here it is thick. That taken with the fact that I am a meat hunter I almost never shoot past 300 yds. Additionally due to the fact that if an animal is not DRT, he many times is not found. A hole going in and one going out gives one two chances to find a blood trail. Conseqently I prefer a heavier bullet, usually 6.5 mm and up for hogs and deer.
Now as to kissing the lands.
It is my understanding that the chambers on production rifles are cut to SAAMI specs. Factory ammo is also loaded to SAAMI Specs. That means that any commercial ammo should chamber in any production rifle of the same caliber. I�ve owned many rifles from A to Z. It has been my experience on most that if one was to load the bullet out to where it kissed the lands, sometimes the base of the bullet does not even touch the case, much less fit in the rifles magazine. Typically magazine length is the most common limiting factor.
Here is an example.

This is the detachable magazine for a Sako 75 Varmint, chambered for the 260 Remington. Sakos are generally accurate and their chambers are not known for sloppiness. Notice the Maximum OAL of the cartridge that can be loaded in the magazine is 2.940. I don't know how you are, but I prefer to have a little wiggle room in the magazine/cartridge box.





The SAAMI max OAL cartridge length for the 260 Remington is 2.800�. I�ve developed a load for my Sako at 2.900 inches. This particular cartridge measures 2.902.




If I do my part the Sako will put three in a ragged hole at 100 yds.




Next, using my Stoney Point OAL gauge and a 125 gr. Nosler Partition, here is the cartridge �kissing the lands�


As you can see, to load this round with the bullet �kissing the lands , the rifle would have to function as a single shot.

Good hunting and best of luck with whatever you choose.

Best,

GWB

If you get the 7, you will still need to get a 243.

I regret the first half of my life was spent without one.

Fun to shoot and with modern bullets it kills like lightening.
