Hey guys I am new to the site, and to reloading the 10mm. I have a G20sf and cant seem to hit a sweet spot! I am using 155gr. xtp,starline brass, cci 300, I've tried blue dot charges from 10.5 to 12.5gr. in 5 shot strings, also no crimp to enough to slightly deform the pill! still it wont group. it acts like it needs more powder! Any ideas?
