Well, after 2 mos of trials, 6 diff powders, following the new bbl break ins recommended on here, putting in a new Timney trigger, I got'er shootin dimes!
My original goal was to get it liken Nosler 140gn Accubonds - and they were not half bad as I was getting some 1 in groups - however in an effort to have a diff bullet as a gauge against the Accubonds I tried a Hornady 139gr and it just kept outperforming.
IMR 4831 was always the most consistent with RL19 in second place...
Anyway this AM I got out with some loads and adjusted seating depth and found my sweet spot! Had 4 diff loads under 1in and the best was a 3 shot .40 group. That's about as good as this old man can shoot and I am sooo happy! I wanted something close to 2900 FPS and ended up at 2910FPS!
Oh, yes Kodiakrain these 4 loads were all neck sized only also!
Thanks for all the inputs guys!
