Hi there

Some of you promoted the 7mm-08 in a recent thread about a BLR project.

Reading your comments, I made some research about 7mm-08 performance and found interesting data comparing 7mm-08 hand loaded with 270, 30-06 and 300 winnie factory load, illustrating impressive trajectory (equal to . 300 Winnie at 300 yards) and downrange energy (better thab old 'O6 and 270 at 400 yards) for the 7mm-08 using 140 to 160 grains bullets.

But those datas were coming from 22 inches barrel tests.

I recently found a second hand 7mm08 for sale but the barrel is a 18.5 inches one (and the BLR has a 20 inches barrel).

How do you think the 7-08 is able to fit so short barrel ? Any speed records from short barrels in 7-08 ?

I had a 20" Win model 70 Syn/Matte carbine, ltd. run in the 90s, it clocked around 2850 w/139s and max load of varget.

My 21" 700s, two of them, one SS other CM, shot 2900-2960 w/139-140s.

You won't get a speed record in a short bbl but you will kill plenty game. The 21" get loud, a 22-24 is better on the ears than an 18.5-20".

What is your style of hunting, game and range? Odds are the speeds alone are fine for killing, it's just knowing your gun, and if that gun is accurate enough to allow you to place your shot. I'd not compare, but appreciate the 7/08 for what it does on it's own.

- Roe deer in open field and woods from short range up to 200 yards
- Wild boar (average = 180 pounders, bigger would be aroune 320 pounders) in open field and woods from short range up to 100 yards. Needs to die quicky after the shot if hunted by night.
- Same games but running, driven hunted (requires more knock down power, probably better with heavier yet expanding and mass keeping bullets) at max. 60 yards.

Must be a Rem 788 if it is a factory rifle. I had one, and there's not a thing wrong with the ballistics, just a bit off in handling. Balance was a bit weird to me.

Sounds to me like that short barreled 7mm-08 should be perfect.

With what kind of load ?

I thought it would be nice to be able to push 140 grains TSX and 160 grains partition at proper expansion speeds.

I believe it would get the job done on stalked game but driven one is the big issue.

I owned a Remington 788 carbine in 7mm-08 a few years
ago, nice little rifle, recoil on the bench was unpleasant
but when in the woods I didnt notice it much. I know a
few guys that own Model Sevens in 7mm-08 and swear by
them when on deer drives. Once I think about it, almost
all the guys I know that own Model Sevens have the 7mm-08
caliber.

If you are concerned about velocity loss in that short barreled Steyr, how about a 140gr partition or 120gr TTSX?
Either one of those would knock the crap out of anything you are hunting, even the boars, I should think.

Just a thought.

Remington made the 788 and the M7 with a 18.5" barrel and for some reason they switched to a 20 and 22" barrel. I don't know if it was ballistics or muzzle blast or what. I had a M7 with the 18.5" barrel and as I recall, it would motor along right well with a 140gr bullet.

i have one of those M7s with the 18.5 barrel. i shoot 120 TSXs @ 2880 fps in it excusively.

it gives me the warm fuzzies.

i'd be a little concerned about meat damage on the feral cats though....

It's a Steyr Scout.


second hand steyrs are like second hand anvils.
i have the mountain in 7-08 and just loaded up some 140 barnes w/ varget.
nice to have that very long steyr magazine to play with OAL. i loaded the 140's to 2.825" and still have 1/4" left in the mag.

keep in mind steyrs have VERY fast barrels. i shoot a little 20" 308 that clocks factory federal GM at 2550 MV.

I think the 7/08 is at it's best with 139/140s if you are talking factory loads. On Boar, other than a 120 TSX, I would use 140s. Those should penetrate fine on any boar, my brother shot a boar w/Encore in 7/08 w/factory 140 corelokt, under 100 yd shot, it did run a little, but the boar was est. at over 500 lbs by a wildlife biologist, it was a VERY big hog. That said, I don't think any other bullet would have dropped it sooner. Perhaps a hit to the spine. Believe my brother hit his behind the shoulder in the lungs.

Steyr's make nice rifles, you should do well.

A 20-22" barrel would be about ideal for most 7mm-08 rifles, I think. For your style, I think 18.5" would be perfectly fine providing the rifle fits you and balances to your liking.

...................GV!..........Take a peek at this article written by Dick Metcalf about a 16.5" barreled Ruger Frontier chambered in a 7mm/08. This should answer your question about 7/08 performance from a shorter barrel.

"shootingtimes.com",,,,,,,,Click onto "Long Guns",,,,,,,then scroll down and click on pg 9 and then find his article titled "Short Answer About Scout Styled Rifles." Note what he writes after the sub-heading "Short Barrel-Long Reach.

7mm/08 140 gr factory ammo fired from a 24" barrel gets an advertised 2770 fps. From the 16.5" tubed Frontier, he chrony`d that same ammo at 2647 fps. There are also other velocity #s in the article.

Don`t worry! Compared to a 22" or 24" er, you won`t be losing much with either the 18.5" barrel or the 20" barrel. The 7/08 is a solid short barreled performer.

I've had some 7/08's with short barrels,18.5-20".They gave in the mid 2600's to low 2700's with 140's.




The 280 Remington is overbore.

gv,

if the price is right - buy the rifle.

It is perfect for tasks you describe.

My personal favorite would be a 120 gr. TSX.

The article big squeeze mentioned summs up the velocity question - in short, the loss is academic.

In practice, such rifle would offer you amazing versatility.
The mounting options alone are great.

You can switch from a low light scope over the receiver to a forward mounted scout scope for drives (with practice it makes a great sight for this).

The flip up sights allow instant use for a impromptu follow up.

I say - go for it.

if you have an opportunity to buy a 7mm-08 steyr scout you should get it. the 308's kick a bit too much for me in such a light gun and the 243's and the 7mm-08's are rare. most having been imported to countries with "military caliber" prohibitions.
If you find that you dont like it let me know. i have a walnut stocked 20" barrel with a leupold 3.5-10 that i'd trade you.

I have a 20-inch BLR in 7mm-08 and an 20-inch Model 70 Compact in 7mm-08. I prefer more weight and less muzzle blast than barrels shorter than 20 inches have. Velocity loss in the 7mm-08 is not much, so going to a 21 or 22 inch barrel should be all about balance and feel for you, not 50 fps.

As stated, the 139-140 grain bullets are the norm. 150s and 154s will start to lose steam with the smaller case and shorter barrels. 160-gr is really in the domain of the .280 Rem, .284 Win and 7x64mm.

For flat shooting to 300 yards, go to the 120-gr BT or TSX.

It is hard to find a Steyr that won't shoot well, and like the Tikka T3, they aren't picky about various loads.

I'm not sure I understand this one Lee24. I have a 20" Barrelled carbine on a Mark V Weatherby in 7mm-08. Great little round and also read Metcalf article on velocity loss. It was an eye opener. Now I can understand why you lose more velocity out of say a '06 length or long mag case as you have powder that has not burned down the shorter tube. But on a case such as the '08 case you have efficency in burn rate which gives you little velocity loss prior to exiting the barrel.

Your comment states that as you get into the heavier bullets, you lose more steam. Wether the bullets is 120 grs or 154 grs isn't velocity lose going to be the same percentage?

I hunt thick woods up in Maine and actually trying out a load in the carbine with a Hornady 154 gr round nose. Should be the Cat's butt on large whitetails in close cover. I've used Hornady RN bullets in a variety of calibers and believe it or not they are pretty darn accurate and over pretty quick expansion. This will also be compared with some 120 and 140 loads I'm working up to see what shoots best but if the shot is going to max out at say 150-200yds this bullet in either RN or SP could be a very good choice out of the carbine version of a 7mm-08
