Anyone using 180 hybrids & 180 scenars with Retumbo? I found a decent load using 83.5grs with, 26 Norma brass necked up, .002" neck tenison, CCI-250 primer, and .020" OTL with both shooting well at 100 yards. I'm wanting to test them at 500 yards to see how it group. Hybrids are 3150 avg, and Scenars are 3180 avg. The Scenars seem to shoot tigher, but will post targets after test.
I know lots are using RL-33 and 195's, but I have a 1:9 twist and shooting sea level to 3000'
H1000 just might be another powder to try with 180's. right now retumbo seems to. E working well, just need to stretch it out and see how it does. The Scenars just stack very nicely at 100 with Es around 12.
