270 WSM loads

[ForneyRider]

I starting to work on these loads now.

Mostly looking at R19 and R22 loads...

Norma has 61.7 of 204 for 3288fps as MAX. 204 is between R19 and R22 in speed(brisance???).
Alliant has 66gr of R22 at 3228fps, and 66gr R19 for 3088fps MAX. Win brass and CCI 200 primer
Nosler says 65gr of R22 in WLRM primed Win brass for max load but highest fps.
Lyman has 68gr of R22 for max load.

Lee book doesn't cover very many powders, except Hodgdon and Winchester.

It was a G&A or Shooting Times article comparing 270 Win and 270 WSM and they used 130gr Scirrocco's with 68gr R22 for max load.

I think all this data was collected using Win brass, except for Norma.

What are ya'll using?

Looks as if Reloder 17 will give better velocity.

I been using H4350, real accurate, but velocity is a little low.

I'm seeing the gamut of Reloder powders, from 17 to 25.

I'm sticking with R22 as I have a few lbs. I've been trying to consoildate all rifle powders to Benchmark, Varget and R22. I really like R15, but Varget has been great and I can get 8lb'ers.
