"Hold Into The Wind"
Be aware,anytime you add weight to barrel,you change harmonics.this can affect p.o.i. and accuracy.For a brake to perform up to it,s design potential exit hole should be only around .020" larger than bullet diameter.This means concentric to bore.Since bores and barrel o.d,s are not always concentric this sometimes dictates 2 lathe set ups.Always do before and after testing.
