I don't have much faith in the group sizes as my scope crapped out shortly after shooting these groupings.

Please feel free to log your favorite loads and data here. The only reason I'm using Win748 is that I have 3lbs on hand. Once it's gone I'll be looking for something else to try.

No one is interested in sharing M14/M305 reloading data?

**I consider these max loads for an M14 without a regulated gas system where I could bleed off some gas. Always work up your loads for your rifle!**

What I shoot:

Primers: Winchester
Brass: Winchester
Bullet: 150gr (Speer Hot-Cor or Speer Mag Tip or other)
Powder: 45.0gr IMR 4895
Velocity: 2780 fps in 22" barrel; 2590 in 19" barrel Groups about 1"

Primers: Winchester
Brass: Winchester
Bullet: 165gr (Hornady SST, or other 165)
Powder: 45.0gr IMR 4895
Velocity: 2750 fps in 22 inch barrel Groups 3/4" average, often better!

Yeah, you're only losing 30 fps by going from a 150 to a 165 with everything else the same, whoda thunk it!
