Sounds like a great set up.
Your dealing with a little monster we can barrel torque. Drive a long, heavy bullet fast in a relatively light rifle and it will roll all over hell.
Don;t know what you think of them but a Holland QD muzzle brake
will stop this nearly 100% and reduce recoil to that of a 25-06-270 class rifle of the same weight.
When you get those Paritions shot up, load up the 200 gr Accubond and you will get some amazing performance. In the tests I have performed, the Accubond will outpenetrate the Partition of same bullet weight when fired out of these high velocity rounds.
Plus, if the parition ruptures the bullet will almost instantly stop penetrating, there is no parition to fail in the Accubond so its even better for close range shots and vastly superior for long range ballistics and performance.
May be the single best commercial bullet out there for the big 30 cals.
