Finally got everything together along with time to start looking . 500 new Starline cases , 1000 MBC 215 SWC , primers are WLP & Fed 155's .
Most people like Unique for these kind of loads . So that's what I did . Tried 7.5 , 8.0 & 8.5grs w/ WLP primer . Of the 3 , 8.0gr shot the best , accuracy however wasn't that great .
Next I tried Universal Clays : same charge weights , WLP primer . Again accuracy not what I want . 7.5grs shot the best of these 3 .
Next I tried SR7625 , WLP . 7.0 , 7.5 & 8.0 . 7.5 shot good but I'd like a little more horsepower . Accuracy was better than Unique or Universal loads above . Good plinking load , but as stated I'd like a bit more authority for hunting , pest removal or social work .
Next I tried 4227 , Fed 155 primer . Shot 16.0 , 16.5 & 17.0grs . Let me just say that in my gun this aint the answer . I believe this powder in this caliber it's like H110 / W296 in that it's all or nothing for best results .
Originally I was thinking a nice middle level cast load but might have to go faster to get the accuracy I want . So I'm thinking about trying :
2400 - 14.5 to 16.5grs
SR4756 - 9.0 to 10.0grs
Blue Dot - 10.0 to 12.0grs
800X - 9.0 to 10.5grs
N340 - 8.0 to 9.0 grs
N350 - 8.0 to 9.6 grs
Have never used Blue Dot , 800X or 4756 before . I've heard 800X does not meter well , all the Blue Dot issues & that 4756 don't like being crowded . N350 looks like a good fit on paper .
I'm also thinking that perhaps a different bullet if the MBC's won't do . Since I no longer cast , I believe that Moyer's & Rim Rock are the only sources for either Lyman 410459 or H&G258 cast bullets . Any thoughts , advice etc . Chime on in as I'm sure someone's done this before .
Bullet sizing ( .411 ) & lube are working fine . No leading & lube star on the muzzle .
