it doesn't matter if i've taken it out of the stock or not (i haven't had to since removing the cosmoline, actually) but all my garand actions need a warmup clip. Maybe it's because i'm using a thin surface smear of autozone wheel bearing grease that smells like a west texas oil well instead of muh red lithium grease but i tend to get failure to feeds on that first group of the day. runs like a swiss watch after that, both the .30-06 and carbine.
