T/C NutWell here it is..
165gr Speer SP
57grs Varget
2,590fps
Hmmmmmm may try a little more powder.Anyone have a clue on what powder to try next..? For better velocity. *NOTE* Same load in my 26" tube went 2810fps that's only 220fps faster than the 16.5" pistol.

FiftydriverT/C Nut,
If you are shooting a 300 Mag(Win ?) I feel you are using much to fast a powder. For that bullet weight go up to something on the lies of 4350, RL-19 or RL-22.
These powders are just barely on the fast side for heavy bullets in a 300 but for the 150-165, they will prove better suited in the short barrel, also muzzle blast will increase but so will velocity, nothin' for free I guess.
Tfy some powders in that burn rate and see what happens, I'm sure they will out run Varget by quite a bit and pressures will be easier to manage.
Good Shooting!!!

Albert T. TomblinT/C Nut try IMR4350 and the 165 Nosler Ballist tip bullet, they work great in my 15" Encore with 2600fps velocity, and 1 inch groups or less.
