The FTX bullet / LVR powder mixture gives a lift on the downrange functionality in the .30-thirty Winchester, most noticeably in retained energy at MPBR. This is because of the higher ballistic coefficient of the FTX bullet.
The powder generating the best velocity is detailed to start with below Just about every caliber. It occurs that Varget generates the very best MV of all powders mentioned inside the Hodgdon reloading desk with the 55 grain Speer comfortable issue bullet.
Hodgdon CFE223 is a relatively new powder and I haven't tried using it within the .308 Acquire. Given that the desk exhibits, Varget and H4895 drop only incrementally in need of CFE223. Loading any of such powders with a hundred and fifty grain bullets gives sound efficiency.
Drop by and find the "Data" tab, then choose "H4895 Lowered Rifle Masses." Hodgdon invites you imr 4895 powder to Make contact with them through telephone or e-mail In case you have added questions on diminished masses.
Varget and H4895 give muzzle velocities within about 5 % of the IMR 4451 load. All a few loads are strong.

I chosen ten of the most popular non-magnum rifle cartridges, from .224 to .308 caliber, Along with the intent of evaluating load and ballistic info for Varget, H4895 and imr 4895 powder regardless of what powder gave the highest muzzle velocity with a particular bullet well matched to every cartridge.
