I wanted to share some pictures of a recent match and talk about reading group shape and reading the shape of bullet holes. 6mm ppc at 100 yards with 65 grain bullets
This first target I tested. 3 loads during the morning warm up match and 30 grains of 133 dotted up nice. So I went with it to the record group. All was going great UNTIl the fourth shot and crap it jumped way out!
The load was too hot causing the proverbial 4 and 1. Take a close look at the bullet hole on the high shot. The bullet hole is oblong the bullet is not stable
On to target number two I incorrectly chose the light 29.3 load and the group went completely flat.
Dang! too light the holes are now nice and round tho
Target number three up in powder to 29.7 now we are getting close But, I need the vertical out. I know I can’t go up in powder or it might spit one out
Target number four left the load at 29.7 and went out in seating depth .002 Bingo! Finally there
Last target load stayed the same another nice group
The only problem is it took too long for me to get in tune all over but the crying.
I’m now on the tune tho and things went much better the rest of the match
