Just got back from my first range session to build up a round for my long range rig. Im still really new to the whole long range game but could you please read between the lines of what I should try next. I'm not completely disappointed but am not happy with the results for first time out. This isn't a bulls-eye gun but I'd love to shoot practical tactical out to 1200m someday. I've included the first 6 groups since as you can probably tell from the first 6 loads, 61.5 and 62 were all over and 62 actually pushed a primer out of the pocket and was beating my shoulder up a little and i was getting the flinch. It also was 90* out so sweet probably was an issue too.
The rounds were Hornady 208gr BTHP Match, 60-62gr, Rem. mag. primers, Winchester brass, seated to 2.9 oal. which i think is sitting right on the lands since I could feel minor pressure when closing the bolt. I need to get a chamber measuring tool and figure out where the bullets actually sitting.
I loaded 2-5rd groups for each charge of IMR-4350 @ 60, 60.5, 61, 61.5, and 62 gr. Loads where shot from 200m through my CEI pro Dig at ten feet ahead.
Rifle is Savage 10 in .300wsm, 26" McGowen #8 target crown, b&c medalist tactical stock, Swfa 5-20hd, LDSP suppressor. shot on Harris bi-pod with sandbags in back on Vietnam era sleeping bag prone.
