Looking at buying a 7mm-08 for a 400 yd deer gun that is lighter on the recoil. Found one I'm intrested in but it only has an 18 inch barrel. Will this short barrel have much effects on its performance? Cons or pros with 18 inch barrel?
Thanks Seth

I always shoot better long range with a longer barrel.4oo yds would be a long shot where I am,maybe not in your area.

Not positive,but I seem to remember factory loads were developed for the model 7 with a short barrel. Probably no help :

400yds no neglible difference unless you're a speed freak.

Yes, you'll lose possibly up to a a couple hundred FPS vs a more standard 22"tube which means a few inches lower at 400.

However if you're shooting enough, and you should be, to know exactly how many inches you'll know where to point it when you need to.

Of more concern to me is how a rifle handles. If that's a lightweight carbine barrel on a lightweight carbine odds are its quick to the shoulder but lousy at range due to shake and wobble unless it's sandbagged on a bench.
If it's a short thick tube in a pillar bedded benchrest or marksman type stock with bipod it'll be rough toting in the woods but set up for range.

Check velocity at muzzle then run the specs on your load including energy and see if you can make the drop and enough energy at 400 yards to make it work .

I wouldn't buy one with an eighteen-inch barrel. It's not long enough to ignite all of the powder in a factory round within the confines of the barrel. On the Fourth of July you could touch it off, just for the nice flare it will make.

If you reload, you might be able to get by with a faster powder. But I'd still let this rifle pass.

I prefer barrels 22-26 inches long.

I'm gonna be the downer but 400 yards is asking a whole lot of a 7-08. Yes the military makes 1,000 yard shots with a 308 However a deer and a human are 2 totally different things. If it is a 7mm you are after for those ranges a 7 Mag would be way more suitable. As far as barrel length look up the load data for the bullet you are planning to use and the first page will give you the test barrel used.

Say what? A 7-08 will kill anything on this continent out to 400yds. Between my cousin and I we probably have 5 short barreled 7-08s and they are all shooters. Kimber Adirondacks. Tack drivers. Practice enough and you get proficient with your weapon. Matter of fact, I've never owned a 7-08 with anything over a 22" barrel. Zero need for a long barrel in them because they're sub-500yd setups on purpose. You need to run your numbers on 7-08s with 140s out to 400yds and rethink your "downer" logic.

OP, out to 400yds you have nothing to be concerned with energy- wise from a 7-08. Everybody thinks you need a freaking cannon to kill deer these days. I think my Adirondack is right at 6lbs with scope and rings and a pleasure to carry and to shoot. It shoots .75" groups at 200yds all day with 140gr Barnes TSX. If you load you can get some Absolute Hammers and the velocity loss will be a wash. I think I'm about 75fps slower with the 18in barrel compared to another one with a 22in barrel. Some barrels are just faster than others.

if we start with Hornady super performance 139gr with a .486 g1 bc at 2950fps mv

with a 200 yard zero we arrive at 400 yards at 2224fps

approximate 2000 - 2200 fps is the velocity where temporary wound channels stay permanent the velocity where a rifle acts like a rifle.

the issue if you get 2950 isn't that it will hit fast enough at 400 , but that you have 20 inches of drop to compensate for and if your off on your range estimation and it is 425 yards it is 24 inches of drop so you need to be right on with your range.

2950 fps is probably from a 24 inch test barrel

an 18 inch barrel will likely give up about 100-200fps

if you start from an 18 inch barrel at 2750fps you arrive at 400 yards at 2055fps so with good shot placement you should still be able to kill a white tail white tail however you are at the outer limits and you now have 23 inches of drop at 400 yards and 28 inches at 425yards your loosing 5 inches every 25 yards.

yes if you can make the shot placement it should work , I do think you are at the outer limits of what 7mm-08 can do


I shoot 308 with 180s and a .540bc my outer limit for myself is 300yards on game not because the bullet wouldn't get the job done if I got it there but because I am on almost the same trajectory as the 139gr from the 7mm-08 24 inches low at 400 yards , which I can compensate for , it is the wind I may have to hold 6 minutes off at 400 yards this means I am 24 inches high and we will say right of where I want to hit my elevation doesn't wander much but I have had the wind change as the shot breaks and I am only holding about a foot right left and about 6 inches vertical and I know exactly how far that target is.

I have 1/3 of the drop at 300 yards and the windage is less than half of the 400 yard shot if range estimation is off by 25 yards it is still in the vitals

and I don't think the 22 inch barrel will make a big difference in range the arc is the arc and unless you drive it harder out of the barrel into magnum territory I think 300 is about as far as non magnum should be expected to take game, the range just because an issue.
even 300 is only with a bunch of practice in different weather and learning how to read the wind and knowing what you can do with that rifle.

if you can get it there in the right spot sure it should be a kill shot , getting it in the right spot is the issue with the variables at 400 it leaves no room for error.

if you can get low and crawl in from 400 to 300 you give yourself a lot more wiggle room on the shot if you get to 250 even better

I have been shooting a 18" rem 788 in 7mm08 since 1984. While i have never shot 400 yds the gun is certainly capable.
Shorter means a STIFFER barrel which i think aids accuracy.
As stated above, its only a deer, a shot in the boiler room and your eating backstraps for dinner.

My favorite deer rifle in A Rem 700 LVSF in 7-08. Think my barrel is 22” long. If Implan to hunt where a 400 shot is probable, I usually take my 25-06 or .270.

I own a 7mm-08 with a 22-inch barrel, and I don't consider it a 400-yard hunting rifle.

I'm partial to 788 also I have a few of them.

Thank you all for your input. Much appreciated.

As said above it could do it. But no long range shooters use short barrels for a reason.

And most long range shooters ain't shooting 400 yards.

I’m sure you are also working on your field craft, to shorten that 400 yard moon shot down to a more conventional 150 yards. The long distance shooting craze emerged from our wonderful troops’ sniping experience in Iraq and Afghanistan. Nothing wrong with developing long distance shooting skill. Heck, we may end up needing it as much here at home as we did abroad. But for hunting animals, the actual hunting part, where we pit our field skills against the nose, eyes, ears and instincts of wild animals, is really the most exciting and rewarding part of hunting. For me, a shot over 200 yards feels like an assassination, not a hunt. I do recognize that there are field conditions out West and abroad where longer shots are either the norm or the difference between a hard but empty handed hunt and a hard but successful hunt.
