Made it out to the range today to test these. Not really that impressed so far... My starting load was 9.0 grains of AA#9. 50 yd groups of five were around 1.0" and the faster I pushed them the worse they shot. Went up by .2 grains to 9.8. 9.6 & 9.8 grain groups opened up to 3-4". 3 shots went supersonic at 9.8.
Any suggestions on other powder to try? I have 150 of these left and some H110, H4227, & Blue Dot...?
