Working up the 222 at 100
From prior, I saw 23.5g of h322 was best, working up In 0.5g increments.
I then narrowed from 0.5 to 0.1 grains 23.3-23.7
All done on Dillon 550 progressive
First the toy
Starting bottom left and going ccw it was 23.7 then .6 at 7oclock then .5 at 9, .4 at 3 and center was 23.3
I did not have a micrometer with me but it appears that the groups steadily got bigger moving down from 23.7 /23.6
I will have to measure but they appear pretty equal. I also may have to go up 0.1 until groups open up again(seen at around 24.0 last time)
23.6
I added a spent 22 Long rifle cartridge for some reference, of course this is slightly an optical illusion making the group size appear slightly smaller but nevertheless still pretty good groups for 100 yards/5 shot groups
23.7
Now
To do it all again and see if I get similar results along w reverse order for barrel temperature
Then to swage my own and see if I can come close
