Problems with first .223 load
I am not new to load developement but this is my first venture with the .223. I have been lurking around in different forums to find a decent plinking round for my Del-Ton 1/9 cl 16" M4. I picked up a pound of h335, 1000 hornady 55fmj-bt w/c and I already had 5000 cci 41 primers to use. I am usung once fired Federal brass.
Ok here is were the problem starts. Hodsgons, hornady, and Lyman all have different min and max loads. So I loaded up 5 rounds each 21.6-26.1 (no signs of any presssure) in .5 increments loaded to 2.200 with a slight crimp from lee FCD. I am shooting from a bullbag at 100 yrds and for some reason i can not get a group less that 5-6 inches. what am i doing wrong?
My thoughts were to go to (1)2.260 on the length (2) not crimp.
