A guy I shoot 1000 yard BR against refabbed his rifle last season to run 30cal 230 Hybrids.
He went from a 6.5x47 Lapua to a 300 WSM. ,, Big expensive change.
Hes running a Lilja 1-10 twisted 1.25 bull barrel.Some how he got the thing to make the 17 pound weight limit.
I get this phone call.
Under 2700 fps hes getting funny shaped bullet holes at 100 yards. Accuracy at 1000 is not there.Hes been playing and he needs to run it up over 2750 to get round bullet holes.
Berger recommends a 1-10 twist.But Bergers Twist Rate Stability Calculator says a 1-9 is a better mouse trap.
Surprised Berger says 1-10 on there web sight..
So far his path down the 230 hybrid side isnt working very well for him.

...Ive been running a 210 Berger LRBT out of a 300 SAUM for 2 shooting seasons now.Out of a 1-11 twisted Obymeyer.
Get 2800 fps with 60g of ramshot hunter.
Never a hint of a odd or funny shaped bullet hole.
Accuracy has been excellent...

Only accurate rifles are interesting.
