270 Ackley vs. 270 Sherman...?

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

Why can't you take a 30-06 case neck down to a false shoulder and fire form that? It would take away one step anyways
 
He can, but using a longer case length like the .270 Win/.280 Rem/AI is more ideal but that's just me.
I'm extremely new to wildcat loads and fire forming brass I am having a 270 Sherman built for me now and was wondering the best way to go about making my brass so necking down a 30-06 is not a good way to do it?

The .270 Win and .280 Rem has a case length of 2.540" and the .30-06 has 2.494". The .270/.280 is a better choice to fire-form to .270 Sherman. Rich (@elkaholic) is the designer and SME with this cartridge.
 
Gotta Love you Guys,.. ALWAYS,.. "Re-Inventing the Wheel",..
The ole' .270 WSM, STILL,.. gets it done, without, the BS of, case forming / fire forming and does IT with, TOUGHER Brass !
With, the "Right" Boolitz and Barrel Twist, there's NOTHING that, it can't Kill in, the USA and further out than, most People "can" shoot, accurately !
But,.. carry on !
