[QUOTE="Mike6158, post: 2918907, member: 1039"] My 7mm Rem Mag wasn't quite as bad as 2" at 100 but some loads would approach 1.8". Today it shoots 0.215" to 0.334" with 180gr Berger VLD hunters at 100 (yes I know, Berger says the twist rate on my Sendero is marginal for these. I agree. I'd rather see 0.100" to 0.000" groups but these'll do). Longer range testing to come. I replaced of the old school brake with ports 360° around. That helped some. After shooting 1,500+ rounds thru various rifles this year I've improved my shooting skills. That was a lot of it. After I pull the trigger on my Rem Mag, I'm still on the scope and the scope is still on or very near the target. Before I fine tune me, that was not the case, at all. [/QUOTE]
