I shoot a 7wsm with a 24" Bartlein barrel 1:9tw
62.9gr of 4831SC
Berger 168VLD
3,032fps from the chrono and confirmed on targets out to 1000yds.
Not sure if it matters or not, but I leave my sky screens on all the time. Never take them off cloudy or sunny. I'm not saying my chrono is dead on, but it's **** close. It's always been close enough to get me on target at distance with it's velocity readings and Shooter app.
