Looking for some info on some long range loads for a 7-08! Ranges to 500yds common.

What would your load be for this application? Thanks CD
7mm-08 Caliber is pretty marginal at 500 yards.........too much drop, too low on velocity and too low on energy.

Obviously, the drop affects ability to hit and low velocity and energy translate into marginal bullet performance.

Good 300 yd. caliber but a man has to know his gun's limitations,

Consider something with more case capacity.

I didn't get what the original poster wanted to hit at 500 yards. If there's deer killing to be done, a 7mm-08 can have more steam at 500 than a 30-30 does at 100. A laser rangefinder, an elevation turret, and practice can take care of the hitting part.

The 120TSX will make 1000ft lbs,beyond 500yds.

From a 22" tube,45grs of powder,dick for recoil and amazing precision.

Hard to not like that.......................

The 162A-Max at only 2600fps,will reap same to 750yds...................

Deer are the intended target. 500 yds is a last resort type deal with perfect conditions. Thanks for your help. CD

MM, just watched a very big bodied buck pile up at 257 yds this weekend with a 7-08. Last year I piled up a buck at 317 yds with the same gun. It's capiable... Thanks CD

The 7mm-08 is a great cartridge, and will shoot right with the .270 Win, but the problem for both is how fast the bullets drop after 300 yards. You can find some great target loads like the ones used in 300 meter running boar out of rifles like the Tikka M-595 Sporter, but that is at known range.

Bullets like the Ballistic Tip in 120 or 140, or the heavier Sierra and Hornady target bullets will all kill deer and antelope at 500 yards.

In hunting, you also have to KNOW the range beyond 300 yards, within 25 yards ( +/- 12 yards ) in order to make an ethicial shot, and be able to hold 1/2 MOA yourself in order to deliver it.

CD,

You must be mistaken! Please send that POS Mnt rifle to me. I will shoot, I mean, dispose of properly! <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

More than capable at 500yds and further with the correct bullet. Silly guys who think speed and flat trajectory are the only factors that kill. Drop has nothing to do with it as long as you know what to dial in. I'll take accuracy over trajectory and speed any day!

Uh...Pretty sure I didn't say you couldn't. Figured I would state my choices if I had to pick. The thread was about the 7-08, correct?

A 145 Grn Speer HotCor on top of 48.0 grns of IMR 4350 leaves my 22" barreled Rem 700 Mtn LSS 7mm-08 at a muzzle velocity of 2,800 FPS.

Stick a bullet drop compensating scope on it like my Burris 3-9X40 with Ballistic Plex reticle and you get the following using the appropriate reticle aim points .

Distance......Velocity........Ft Lbs.........Bullet Drop.......BPlex Impact
Muzzel.........2,800..........2,523.................0............ -1.75"
100 Yds.......2,601..........2,177.......... -2.3"............. 0.00"
200 Yds.......2,410..........1,869.......... -5.4"............. -0.23"
300 Yds.......2,228..........1,598.......... -23.3"...........+0.71"
400 Yds.......2,053..........1,356.......... -43.9"...........+0.80"
500 Yds.......1,886..........1,145.......... -72.5 ............+1.54"

I've tested my gun out to 300 Yds and like the above chart shows, it's prety much dead on at 100, 200, & 300 using the appropriate reticle aim points. Can't see myself taking a 400 or 500 Yd shot so I have not tried it at those ranges.

With a properly tuned load, a bullet drop compensating reticle such as the Burris Ballistic Plex or the Leupold Boone & Crocket takes the guess work out of hold over and prety much makes trajectory a moot point (as long as you know the exact yardage) and even at 500 Yds the 7mm-08 has plenty of velocity and energy to do in a whitetail...............

HOWEVER!........wind drift is a whole nother matter. At 500 Yards with a 10 MPH cross wind the above load would have 20.6" of drift. Even so....the Leupold Boone & Crocket reticle has windage aim point indicators for 10 MPH wind at 300 & 400 Yds and their Varmint reticle has 10 & 20 MPH aim points for 200, 300, 400, and 500 Yds.

400 Yds and more is a loooooooong way to be shooting at at deer though. I passed on a shot last year that was later measured as a 390 Yd. I didn't have a range finder and was not comfortable with my "open ground" guesstimate. Even though I had a rock solid rest and would have been shooting with the wind, it turned out that it was good that I passed on the shot as I was guessing it to be 300 Yds. Even using the 300 Yd BPlex aim point, the shot would have been 16" lower than where I was aiming.

I think I'll just stick with trying to get closer!

120's will retain 2000 fps impact velocity,to the 500yd line and drops 8" less when zeroed likewise.

I love them bastards...........................
Stick-you may well love those bastids...but I know of 3 lopes from a couple days back that didn't love them....grins

On opening day of lopes I beat up on 3 with the 120 TSX out of my Mashburn.

At least I had fun.....grins

They are loaded ahead of some 22 for this weekends elk forray.

Dude...I think you meant a man should know his own limitations.

Neither the gun nor the caliber is limited in it's ability at the distance mentioned....provided a guy isn't swinging a Tikka.....grin.

Have to wonder where some of this stuff comes from. Lee, pull over and wait for the 'ludes to wear off.....
Posted By: Brad Re: 7-08 and extended ranges - 10/19/06
Dave and Stick, why the 120's over the 140's? I'd imagine at some point the 140's would overtake the 120's no?
Posted By: Big Stick Re: 7-08 and extended ranges - 10/19/06
Recoil is dick,they strike like lightning and gobble up Real Estate with enthusiasm.

Have killed Deer,Bear,Elk and Moose with a 7-08 and 120's,have yet to shoot something twice.

Couple that in a short/handy rifle and there isn't anything left to yearn for,except more tags...................
Posted By: Brad Re: 7-08 and extended ranges - 10/19/06
I gotta get a 7-08 and give them a whirl...
Posted By: C_ROY Re: 7-08 and extended ranges - 10/19/06
What length barrel do you prefer 20" or 22"?

I am in the market to get a 7-08 and I am trying to decide which barrel length is the optimum?


Thanks.
I have very little experience shooting 140's. My Montana shoots 120x's and 120 vmax's to nearly the same POI and it's a convienient situation.

Both bullets have performed well on deer, and come to think of it, a bear or two....

At Brother Bill's wedding, lotsa folks were hitting 12"x12" targets at 350yds from our deck with our Montanas. Some of them were folks without a lot of trigger time, and the 7-08s were a hit among the crowd.
Posted By: Big Stick Re: 7-08 and extended ranges - 10/19/06
Have often after the fact literally sat down,rolled the rifle over in my hands,trying to figure out just how the [bleep] it routinely/reliably do what it do.

Shrug shoulders,punch tag and start butchering..............
Posted By: Big Stick Re: 7-08 and extended ranges - 10/19/06
Have had 'em from 14" XP-100 to 24" and none of 'em never not worked.

Can't see going over 22".....................
Posted By: Big Stick Re: 7-08 and extended ranges - 10/19/06
Brother Bill summed it up nicely,with a distant Bear,when after piledriving same less an aftershock wiggle via non-CNS poke...he said simply: "HOLY [bleep]".

I concur.....................
Funny thing, that was via Vmax....and I recall a few folks here saying those aren't even deer bullets....

And the range in question was a fair piece further than the 300yd limit mentioned here a couple times....
Posted By: Big Stick Re: 7-08 and extended ranges - 10/19/06
Nearly a couple times,pass the limit mentioned.

Semantics........................
Musta been dumb luck.

Then again......Bill's 445yd (lasered) October buck from last year....

I believe I'm seeing a pattern....

Too funny.

Dave, that alone would win me over... very cool when that happens.

BTW, great pic of Brother Bill and his deer.
Interestingly, my Montana 300wsm does the same with 168x's and 168 Amax's...though it wasn't a surprise, and was actually the intent.

I leave Tuesday for 4 weeks of blacktail sport. Hope to have a few more pics like that one....
Posted By: Big Stick Re: 7-08 and extended ranges - 10/19/06
The boys at work have been telling me about shooting afar,tackle selection and the like. I left them all to stew on 2 words,after the Hunt unfolds and the next R&R is over.

That word is "toldja so" and it'll be some very good bidness for Cabela's,Midway,McMillan,PacNor and a certain 'Smith.

It'll be funny,for a very long time....................
Posted By: Brad Re: 7-08 and extended ranges - 10/19/06
Good luck Dave... looking forward to the pic's man!
Posted By: Big Stick Re: 7-08 and extended ranges - 10/19/06
Boxing up my Classic Swift to get rebarreled 22-250AI,want me to poke your LVSF in there,for 223AI conversion?

Should have 'em back,by next week,if planes fly....................
At last count, I believe there are 6 slopers and two Campfire members headed for Paradise for the rut festivities. Fortunately, they're not all coming at the same time.

I suspect there will be some pizzed off wives, post-hunt. That, due to heavy Xmas expenditure for new gear.

Them boys are gonna need to re-outfit......I've been there....grin.
Yes....please do!
Posted By: Big Stick Re: 7-08 and extended ranges - 10/19/06
I was rubbing in the forthcoming expenditures,but it was falling on deaf ears...just easier to hand someone a rifle,after they've shot their's.

LVSF will go in the box and I'll call The Pimp,to see if he has something he needs built too,prior to poking it enroute.....................
Appreciated...

Posted By: sscoyote Re: 7-08 and extended ranges - 10/20/06
No problem with a 7-08 to those ranges. Heck, we're doing it with our handguns. BUT, a tested tactical-type system must be established.

My Savage Striker 243 WSSM took 2 antelope does out of the same herd just a week or so ago. 1 was 330 lasered (Leupold Varmint Hunter zero-1.7 stadia units down), next was a 420 yarder right at 3 stadia units down-- no wind. Load= 115 Berger @ 2525 mv. Nickle to quarter-size exit wounds on both.
Posted By: captdavid Re: 7-08 and extended ranges - 10/21/06
Sorry I got on this late. I used a Remington VSL 26" barrel as my sendero rifle for several years, until I wanted something more, and sold it. I still twitch. In that gun I was able to get 2800fps or so using 140BTs. On the other hand the Hornady LMs(139sst) shot 2980-3005. These were the highest and lowest chronied with most shooting about 2990. These shot 1.25" groups in my gun. I found that bullet to be plenty tough for deer beyond 100yds. I never shot anything closer. With that in mind I loaded and shot 140s for practice and when I knew the ranges woukd be less than 250yds or so and used the LMs if I thought the ranges might be long. I now have two guns, a 280 and a 7x57 that do what that one did. Unless you need or want a carbine, I'd go with a 24" barrel. The 7-08CDL, 700 not 7, comes to mind. capt david <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" /> <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

Yep, the bug bit me, I ordered a Stevens Model 200 for giggles and we'll give it a spin. Going to stick those 120 TSX's in it.
Ok, pleading ignorance, what are the blue colored rings at the muzzle of the barrel?

My guess is tape. I do the same thing, only mine's black.
