270WSM vs. 7WSM Terminal Performance

I'm trying to decide between these two for a new barrel. I'd like to shoot the 150/140gr Berger(277) or the 168gr Berger(284), based on the results from previous hunts with Bergers.

I think both would have great long range terminal performance(have several 500yd+ food plot stands). Often though deer/hogs are within 100yds where I hunt. And at the moment I don't have a separate "woods" gun and this will have to do it all for now. Does anybody have experience/photos of how the Berger's perform above 3000fps?

Which would perform better on 200lb deer / 250 lb hog?

270 WSM 150 Berger ~3,200fps - 3,000fps (from muzzle - 100yds)

or

7 WSM 168 Berger ~3,000fps - 2,800fps (from muzzle - 100yds)

Are the Berger's designed to penetrate/expand @ ~3,200fps?


Thanks,

Adam

Both are going to knock over deer and hogs. Each is significantly more than sufficient.

I'd go with the .270WSM because of what I've heard of the superior barrel life over the 7WSM.

Re: 270WSM vs. 7WSM Terminal Performance

Good point on the barrel life. I know both calibers are sufficient for the game hunted. I was mainly questioning the Berger's terminal performance at high velocities.

Some members are getting 3,400fps with 130gr in the 270WSM. I know the VLD's perform well impacting < 3,000 fps. I haven't read much about bullet performance on game over 3,000 fps with a Berger VLD.

Berger hunting bullets are not designed to be a "tough" bullet. They are not solid, they have no partition, they are not bonded, and they have no cannelure. They are a jacketed lead bullet.

Re: 270WSM vs. 7WSM Terminal Performance

I shoot the 140 Berger out of a 270 WSM at 3307fps, I haven't got it on enough game to know all the variables but so far under 400 yrds they go in and then shread everything inside of a 8in circle and you find the jacket under the of side, DRT
The 270 WSM get's there in a flat hurry, I've got almost 800 rounds through mine and it still surprises me some times, and man it hits hard. The first couple deer I shot with my dad spotting and he was just shock at how hard they hit, kinda gives ya the giggles.

I favor the 270 anyday of the week over a 7mm when it comes to putting game on the ground, every year I try to salavage meat off of critters that have been pounded by 7mm's that couldn't get it done in one shot. It's my very biased opinion but there is something that isn't quite right with the 7mm when you look at terminal performance vs a 270 cal.

+1 with Bigngreen. I know that the 7mags are accurate and launch a bigger bullet, and they have a huge fan base for good reasons, but it has been personal experiences that has prompted my love/hate relationship with them. Ill take a 270, or a 30cal over a 7mm annyday. Again my very bias opinion.
I figured Bigngreen would jump in on this thread before too long, and he has more kills with his 270wsm with the bullets in question. But I can whole-heartedly agree that the ''smack down'' you can throw with the 270wsm is unbelievably impressive! Even on BIG bears up close and personal

Re: 270WSM vs. 7WSM Terminal Performance

Thanks for the good info. Some reason I was skeptical that they might just blow up and not penetrate at high velocities.

On the .277 vs. 284 now that I read your posts I have noticed similar results. Every deer I've shot with my 270 Win (used Hornady 130's before I reloaded, and Berger's since) has dropped in their tracks. My main hunting buddy uses a 7 RM(partitions) and they consistently run 50+yards unless spine shot.

I can't quite draw a conclusion as to why, more surface area/bigger hole, higher velocities, more mass = more momentum/energy.

Oh well, I guess the proof's in the venison.
