2703 to 2689 fps over 5 shots.
Intitially I was bummed it wasn't faster...but it's shooting good, so I'm happy. It's done two groups better than the one I posted, but the paper target got soaked even after drying out in the morning that I didn't have any proof
. So I posted the best group I did with the load on the next day. I'm done fooling with it for now.
In using 2700 fps/300 OTM in the BR2...shooting next to my buds rifle shooting a 2775 fps 300 NAB...I think out to 1300 we we're real close on elevation, and 'cause the conditions were excellent, windage was damn near the same. I was expecting a bigger difference despite having looked at it before.
Fellas-If you've got an 9 lug Weatherby in the safe that isn't being shot...and it's not a Lasermark, or other exotic model...and doesn't have sentimental value to you in it's original config....I say start a build on it!
