Mission: Short action, competition "grade", ground-blind oriented, short barrelled, suppressed hunting rifle.
I own an Impact on an MCS TCS, with a Kahles 6-24 in 6BR. The thing shoots much better than I can, yadda yadda. I'm planning to form 1 the action for this project, if it comes to be.
Seeing how easy-mode the BR variants are, as well as how efficient the case is, I don't see a downside to necking up some Lapua brass and running a short barrelled 6.5 BR. I've read that some of the guys experimenting with this cartridge in 2008-9 were seeing 2800fps or more pushing 140s. Maybe even 2900 but that was really pushing it, even for BR guys... Also, this was from 26" barrels. Assuming 30fps per inch, cutting 14", I'm guessing a loss of 420fps from their numbers?
My question is, does anyone know or can anyone help me get a good idea what velocity to expect from a 12" 6.5BR, pushing 130 Berger VLDHs?
If I can't get 2600 fps from a 12-14" barrel, then I might re-think. Even at 2500 fps it's worth doing to me, but getting 2600 is the goal.
