Home Forums Hunting & Shooting Hunting Rifles 7mm rem mag Mountain Rifle Build

I am on topic.

I make the point that a .277" can to what a 7mm can!

Thus a Kimber Montana in 270 WSM would be a complete rifle ready to hunt that will do what a 'build' in 7mm might do!

Kimber Montana 270 WSM.

Can it shoot a .661BC at 2860fps?

That question will require a psychiatrist and several days to answer...

A .543 at 3,000 won't suck.....

No it can't however for the game and way I hunt all year such a load would not be optimum in terms of trajectory, recoil, richocets etc.

I have a 7mm WSM that's shooting the 168 VLD's well. Not much use for it here.

For VT I use the .358 Win 99F. Optimum for my woods.

Got one?

If you run a faster twist barrel it can. There are some .277 cal bullets with that high of BC. You might run into some COAL issues depending on the magazine in your rifle.

Seriously I don't know why you want a sub 7.5 lbs magnum rifle. I think a 7-08 would do 90% of what the RM would do without all the recoil. I'm not recoil shy and realize that this isn't a shoot often rig at the range but a hard hunting rifle.

I have a M70 EW .270 in a M70 FWT Edge stock with a VX3 3.5-10X40 CDS mounted in Talley LWT it weighs in at 7 lbs 13 oz. It's fun to carry and pleasant to shoot as long as I'm not pushing 150's too hard. 2900+ with Mag Pro is reachable but 2790 shoots pretty nice and isn't as hard on the shoulder, but I stick primarily to 130's.

I believe the difference between the .661/ 2860 load and the .543 / 3000 load is a whopping 10" of drop and 10" of drift and about 100 FPS at 1,000 yards.

But rub one out if you want...

I've no interest in single loading rounds, so the COAL length would be a no go from the start for me on the 270 specialty bullets. That 180 load is a pleasure to shoot from any position out of my 8.25lb rifle. YMMV.

2.918" kiss in a 3" magbox, IIRC

No it won't, but it ain't close to a .661 at 2860. Not even on the same field.

10" and 10" is a pretty BFD if you ask me, for a negligible difference in recoil.

I'm not talking about the .543 or whatever bullet, taylorce1 was saying that some 270 bullets got up to a .661 and there's no way in hell those stay in the mag.

Edit: guess I shouldn't say no way in hell. I don't know the length of those bullets.

Never said they'd be single loading just that different rifles allow for different mag length. I can't imagine the specialty .277 caliber bullets being that much longer or shorter than your 7mm's. YMMV

Drop is on the dial and if you can call 2mph of wind at 1k, have at it. That's about 2" difference at 500, which is further than 99% of dudes shoot. BC aint exponential.

BC ain't about being able to call wind either, but I'll sure as F U C K take a .661 over less, simply BECAUSE I can't call 2mph of wind. I'll take that extra cushion very day of the week... But you knew that.

Your "cushion" is about 6" at 1k with a 5 mph variance, but you knew that. And you also know there's 99 problems and 6" of pfuqqing drift aint one.

I certainly get you desire for more style and this has been mentioned so you can probably just ignore it but... A T3 Superlight with a few upgrades can certainly class it up. Maybe a Carbon camo Manners SL, fluted bolt with aluminum shroud would certainly set it apart from the crowd for not much more than a Kimber.

I suppose I have just fallen for my basic Superlight more than I ever thought I would...

I watched a mule deer get plowed tonight by a 7mm 168 VLD at 500 yards in a 10mph wind, and I guarantee you that the dude shooting wasn't wish he was packing less BC around, especially after he stuck it right behind the shoulder. But WTF do I know... Smart guys opt for less BC I guess.

Per JBM, there is a 13" difference at 1K..Which allows a pretty good cushion over the .277,

Kick the .661 upto 3k, which I shoot it at, out of a 24" tube, the advantage is over 20"..

Paper ballistics are one thing. Actually shooting another, I promise you the advantages are pretty obvious in real life.
