Got home from work with just enough time to put a 12 break in rounds through the 8 twist on my Ruger bolt action. Just shot fireforming loads which have proven to shoot pretty good from AR barrels.
50 gr Bulk Rem.HP ahead of CFE 223.
I always let the barrel tell me how many 1 shot/cleans are needed before shooting a 3 clean then a 5 and clean.
This one was rather good from the start other than the sludge CFE produces.
Shots 8-12 produced a .42 ctc group so think it's going to shoot.
Since its an 8 twist I throated it for 80 Eldm's @ 2.3 which put bearing surface just above neck/shoulder junction and will still feed from uncut AR mag which the RAP has.
