Boss systems come with reccomended settings by brand/bullet weight, so check your booklet. I'm considering just taking my boss off and finding a load the bare barrel likes. Though my .300 does shoot great with it.
Maybe can find boss settings at their website....
I am not sure if you have considered this, but I bought my .270 w/ boss about 15 or 16 years ago. I loved being able to dial it in, but I did not like the "report" of the shot. For about 30$ I bought the BOSS CR ( conventional recoil ) and I still get the ballistic optimization, but it shoots with standard recoil and no loud report or extra muzzle blast. I have never swapped it back out. I love the gun the way it is now, and it is a tack driver.
God Bless
