All of us end up doing what works for us as individuals, it's good to have a choice or a way to tweak, I have a friend he's not on this site but he is very much a proponent of knurling, we go back and forth a little bit when we talk about it,if you think about it when you decide to knurl bullets it is of course to improve your groups consistency,, I have the last couple of years become a plastic shooting machine not because I set out to do that and I don't even like the word plastic, I sure don't like the French word I can't even pronounce it and no offense if you're French,, nevertheless I find myself successful day in and day out ,my plastic loads all shoot less than an inch most of them hover at a half to 3/4 and most of them do that with at least four to five shots not three I don't say that to stick my chest out,, I never knurl,, if I feel the need to because my bullet is too loose from the plastic I switch bullets or I switch plastic again if I was just dead set on using a specific bullet I guess I would do whatever it takes to get that specific bullet to shoot its best ,I would knurl,,, since I have so many bullet choices I just switched bullets to give me the tighter fit,,, I do not necessarily have a better verbal stance or argument or position but I have over a dozen rifles today right now that hover at a half inch to 3/4 with plastic loads that I do not have to touch the bullets only load them in the plastic and shoot,,, that screams at me,,,,,, again knurling to me is a practice we have developed as shooters to overcome poor quality in what we're sold. I am able to achieve what knurling is trying to accomplish by simply switching bullets ,and by adjusting my load, the powder charge.
