Started out with 12 rounds left over from yesterday's 100yd break in / zero session ...
1x Fired Lapua Brass ( from my bolt gun ), 175smk, 44gn Varget, FL Rezise, Shoulder Length 1.623~, Trim Length ~2.005, Seating Depth 2.200 to OGives, with .0015-.002 neck tension... .336 bushing...
Completely clean / decoppered barrel...
First 7 rounds Upper Left
Last 5 rounds Upper Right
So I wanted to try some rounds with a .334 bushing (.0035-.004) tensions... everything else the same.
First group Lower Right, First two shots are bottom pair, ok cool, about an inch from center ... come up .3mil (1.08in) 3rd shot High... ok come back down .2 ... 4th shot High left...
Hmm wtf over im thinking... ok...
So i grab 3 more rounds (with the .334 bushing) out of the box of 50 I have ready for the 1k range today...
So I bang 3 out and that is the group (lower right)... ok well im thinking shit 1k is gonna suck today, but wtf lets roll with what I have...
So go out to the 1k range start at 200yrd ... here is my target...
Full Target
CBS 10 ring at 1 oclock make some adjustments ... shot alright... blew the 300yd 2nd shot spotter out with my 3rd shot.
can see the rest of the impacts marked with yardage and shot numbers... went semiauto crazy at 1k ... might have made the pit puller mad
had 5 round group just left of the target probably about 1 MOA... damn that wind...
First 1k shot was at pasty at the bottom of the target... that was a 10.8 mil shot... corrected up .7 i think and ended in the head... settled in on 11mils and had a really decent waterline at 1k, lots of impacts on target... except that rapid fire group just left of target... dont judge !
Stayed Super Sonic to 1k ( DA was 1800 by noon, temp mid 70s )
close up of my CM shots
rifle shoots ... and once i get the load dialed in ... im gonna bring some hate on target!
