Using Alliant RL 22 powder, I have experimented to find my max load and best accuracy for long range moose hunting this fall. At 500 yds I still have 2000 ft-lbs of energy. 

I found that each bullet type responded well to incremental loadings of Alliant Reloader 22 powder. This powder has been known by some hand loaders, including me, finding lot to lot variation thus load data I worked up is for my rifle and this powder lot only.

My first objective was to be safe and inspect each round before proceeding in incremental increases until either I achieved my velocity/energy goal or ran into case/primer concerns. I was able to achieve just over 3000 fps with nary an issue, even with a 9.5 barrel twist. 

My COAL objective was to set it at 20 thousandths less than the rifle lands and chronograph each bullet, then shoot for 3 shot groups at 100 yards. .On  the first pass, I achieved a 7/8 inch group at 100 yards with outside temp around 70 degrees and a cold barrel.

My Timney trigger was set a 3 pounds and worked crisply. Thanks Timney!

My Leupold VX-6 3-18 was set at 10x. Love my Leupold!

I believe 3 shot bench groups are all that is necessary for hunting accuracy.  It is very rare to fire more than 3 rounds at one big game animal. My confidence is very high with this Browning in hand. Next is to shoot off hand and with a tripod type rest and shoot a fast follow up shot with the short 60 degree bolt throw.

Good Shooting!
