Mr.C Posted December 23, 2020 Report Share Posted December 23, 2020 Do any of you kind fellows have favourite load for 223 using rs50 under Matchkings in 77gr? Tia Quote Link to comment Share on other sites More sharing options...
buddy.223 Posted December 26, 2020 Report Share Posted December 26, 2020 Difficult to give you an exact weight without knowing, your brass make & oal, but weve found a full case, just before the bullet compresses the powder charge produced the best es and accuracy with 69 - 80 g bullets. Never saw any pressure signs in various actions. Quote Link to comment Share on other sites More sharing options...
Mr.C Posted December 26, 2020 Author Report Share Posted December 26, 2020 Cheers, intend reusing GGG cases at stock oal. They will have to fit a standard mag. Tbh the factory 69's were incredibly accurate at 600yds but want to try and push out further. Quote Link to comment Share on other sites More sharing options...
mitch308 Posted December 26, 2020 Report Share Posted December 26, 2020 I use 24.5 gn Rs50 /77gn SMK (same for TMK as well) 2.250 OAL for an ar15 mag , really accurate load, I have reloaded GGG (milsurp) cases but had a few case separations after 4-5 reloads Quote Link to comment Share on other sites More sharing options...
