[quote=country_20boy]Bump this back to the top for additional questions.
I've tried RL-16, 4064, 4451 & IMR 4350 with various powder charges from mid to max according to the books I have. Virtually everything I've shot groups about 1 3/4" to 2 1/4" with the occasional 1" group that gets me excited then I can't repeat it next time out. So far nothing has really beat the Hornady Superformance 80 GMX factory loads that go about 1.5" and are screaming.
I really want to hand load the 80 TTSX, so I'm not giving up on them yet. Suggestions? I'm loading to 0.050" off the lands which is also only 0.004 longer than Barnes suggested OAL. Should I take the "best" load so far and play with the seating depth?
Also I know this is a factory model 7 with a cheap wood stock so I'm not expecting 1 hole accuracy but +/-1" repeatable would be nice.
Thoughts?? [/quote)
I used 41.0grs. of RL17 with a Federal 210M primer seating the 80gr. TTSX 2.620" OAL and get 0.300" 3-shot group at 100yds. I chronographed it at 3045 fps. Haven't shot any animals with it yet. Hopefully has enough velocity to open up.
