People get lazy after shooting a bunch of 6mm's, .223's, etc. Myself included.
It's why I'm an advocate for .308 as a training round. My 22" unbraked .308 can be pretty unforgiving of lax fundamentals, much more so then my braked .300NM.
I plan on shooting my .308 rifle a lot more in the coming years, including taking it to some matches.
