Feenix- I think that leaves you, me and budlight as the 270AI believers!

Pretty good company from where Im sitting!

Have you tried any of the Nosler LRAB in 150 yet?

With RL 19 I hit 3200 fps and great accuracy. Primer pocket life is a little short, but I didn't make this rifle to shoot at 308 velocities!

L:DL! I'm fine with the short list. :cool:

I got some 150 LRABs but can't seem to find some range time lately. Thanks for the RL19 pointer.

Cheers!

Need some knowledge friends. What is a 280ai necked down to 270 called? Secondly it seems a lot easier to neck down a 280ai than do all that stuff to get a 270 Sherman, unless of course a 270 Sherman is a 280ai necked down.

That is exactly what I have been thinking now for some time. Neck down 280ia eliminating going thru with fireforming and such. Nosler already producing 280ia brass. ctw

Such a shame considering you already have the 270 Barrel Blank. I was going to recommend the 270 WSM and just bypass all the wildcat bs as it performs out of the box. The 6.5SS should be a hoot.

I like both of those you mentioned above as far as coolness goes, when I built my 270 win I asked my smith about the ai version and he talked me out of it just because the standard 270 works so well with so many ammo options available. My 24” barrel runs 150s at 3050, 140s in the 3150 range (rl 26). I owned a wsm and really liked its performance as well. Obviously it will run those 100-150 faster just to give some insight to the benefits of newer powders in older calibers. If your a tinkerer by all means go for it and don’t look back, but the performance to me was never worth the extra work. Best wishes and we look forward to hearing which caliber you decide
