I have a Lymanns 48th edition. However it is copyright 2002. Do I need a new one? Also, I have no clue what powder I should choose and why. Need suggestions.
example. For 175 SMK Lymann nanual recommends IMR 4895 but also bolds N550 as a probable best accuracy load. 5K psi pressure differential for nearly identical velocities. Other threads talk about RL 15, My guy in Lake City says currently M118LR is using Saint Marks. Hence the question of what powder and why?
Specs: Its a LaRue AR10, 308/762, 18" PredatAR barrel, 1"10 with a Mozillo Brake. Waiting on the can since Dec 2018. Will be seating 168 & 175 SMK in LC M118 LR brass shot by me from above mentioned rifle. I also have a massive pile of 2016 M80 who's brass will certainly get into the mix soon enough.
Do I need new manual?
What powder and primers?
I live in MN so temps could be anywhere from 0F to 100F. Maybe even daily LOL.
I was looking at CCI 200 and BR2 primers. My pin is spring suppported so I am not worried about slam fire anyways.
