70g of Retumbo. .08 off the lands.
I have to bump the neck back after each firing. Not much but 1-2 thou.
RL22, VV 560, Retumbo, ImR 4831 have all worked well.
I use Federal 215 primers.
Currently trying to get the hang of runout and neck turning. THe groups I shot today blew my mind. The best brass shot the largest group and the brass that I thought was the worst with the most runout shot just less than 1/2 MOA at 200 yrds. Currently I using the fact that I have poorly turned necks and poor neck tension for my excuse. It may change next week.
Just when I think I know something I get a reality check.
PS on the MDWFP and MSDucks I'm known as Blackduck.
