My 270 has a short barrel (for now), I have a H4350 load that shoots 140 Accubonds great.

Better question is what twist would you need in a .270Win to stabilize it?

My bet is factory 1:10 wouldnt work.

The 169.5 Wildcat has been shot from a 1-10 twist 270 WSM and it was stable, as far as I know. It's got to be border line though, I've got to get down and pick up a barrel that I have in a 1-9 twist for my 270 WSM.

I'll know how fast they go and how stable they are in a 1-11,1-10, and 1-9 twist 270 win and 270 WSM barrel about two hours after I get my grubby little hands on some!!!!!

When you get some let me know how they do out of a 10 twist. Id like to try them out for elk season if theyre good to go. Any pics of em yet? How fragile are they? What do they cost per-100 or 50?

And to answer the origional post. Out of the two cartriges listed, Id go with the 270. Just my preferance of the two for hunting big game. Both are great calibers, and both will work for hunting big game within reason at reasonable range......... wich for now is about as far as I can accurately shoot anyway, 6-800yds and less with the right bullet and conditions and shot placement. Some may push that further, some may feel its pushing limmits at that range. Its a fine line between opinion and physics. Just my 2 cents.

Re: .270 Vs. .308

I have a 270 h & r ultra comp and they don't make them anymore but I drilled a deer at around 1430 yards and I also have a 308 and I did some comparing and found the .270 beats the 308 in range, damage , and trajectory

Re: .270 Vs. .308

Thread is back from the dead in less than three years?

One good thing about 270 over 308 is you can buy about all the 270 ammo you want right now. Not so easy with 308.

Re: .270 Vs. .308

I have both. I have several 270s and one 308. The 308 kicks a bit more with the 150 NBTs over IMR4064 even though it is a heavier rifle with a Sako M591 action. It kicks more than any of my 270s.

Perhaps it's a finicky rifle and to be honest, I've not spent a lot of time with it but the 308 has been more of a challenge to get an acceptable load over any of my 270s for unknown reasons. I use Lapua brass in the 308 too and only Federal match primers. It has an Obermeyer barrel on it sent straight from Boots himself.

I'm sure one day I"ll get out the 308 and have a go with it. I put in for CO black bear this year. If I draw, I'm taking it and the 30.06, both with 180s.
