[QUOTE="remingtonman_25_06, post: 135658, member: 1403"] I have been working a little bit with the 175g ULD RBBT out of my 7 RM. I have H1000 and Rl-22 powder to try. I wanted H1000 to perform better as I want to use that powder instead of RL-22. I just wanted to get a quick idea of what might work w/out loading to many bullets. So I loaded up 2 loads with each powder, totaling only 12 shots. 1 load is 3 shots to me. Anyways I started at 62 and 63g RL-22 and then went with 65 and 66g H1000. W-W cases, Fed 215 primers, and OAL of 3.375" was used for all tested. Both the 62 and 63g RL-22 loads put the first 2 touching or in the same hole pretty much, but threw the 3rd one out at least an inch [img]/ubbthreads/images/graemlins/frown.gif[/img] Velocity was about 2900fps.
