CLeaning between every shot for the first few, eveyr couple after that, every five after that and so on... doesn't take any amount of time.
It certainly has proven itself time and again for me. Fouling wise at least.
And I note that the folks that say it doesn't need to be done, generally are not bragging about accuracy, .75 or 1 moa is a JUNK barrel IMHO.
YMMV, my thoughts on it, its never hurt a barrel to properly break it in, and if it takes and extra hour or two of time and you don't have it, youdon't have lifes' priorities straight.
