Worked on some 223 and 243 ammo this weekend. End results are some tested eyeball busters from my varmint guns. The 223 are 53 gr Vmax with H322 going 3350 and the 6mms are my long range rounds, 107 gr SMKs with IMR7828 going 3000. Can't wait to get back to the range to try to improve my best group at 1250 with these babys!
