Long Ogives Fast Twist What Powders?

[MOOSE 4 GOD]

Hey Guys:

Got a TC PRO HUNTER 7MM REM MAG. After several attempts I have one bullet that is awsome. H4831 with a Speer 115 gr. hp this thing out to 200 yds. will shoot 5 shots a quater will cover. Now for the help I need a 1n9 twist barrel 28" long Hornadys 154 Interbonds, Speer 160 gr. SBT, and Combine Tech 150grs. will not stabilize at 100 yds. I've tried R-22, R-15, IMR'S 4831, 4350, 7828. H-4831. starting loads to just under Max loads, Mag. and Large primers. Now I found This gun with the 115 gr. hp likes a running start to the lands as a matter of fact .50 Thnds. I also have tried this with all the boat tails with the long ogives and can't get it under 1.75 at 100 yds. Oh yeah one more thing All the long bullets I have tried from .05 to .50 from the lands and all in between. I have even tried Hornadys 154 Round nose that is a flat base like the 115 hp. Withe these heavier bullets should I try a faster burning Powder in this twist rate barrel. Any help would greatly Be apperiacated.

Thanks so much For Your Time
