R#19 is the best, start off at 45.5g with a 100g bullet and work up...ain't life a [beeep]???????
Pioneers often end up with their face down in the dirt with arrows in their backs!
Start off a little lower and work up, one shot, .1g at a time till you reach a max load with your rifle.
I use a CCI-250 primer, jam the lands .001.
No freeking telling what your rifle may like, fast twists are a screaming [beeep] unto themselves...no crap! And you thought you were doing what everyone eles was doing? Right.........!!!!
