Same thing happened to me with new Starline brass. I almost got carpel tunnel syndrome trying to prime them with Federal 210s. I switched over to CCI 200's and they were easier to prime - AND my Spreads went down!I bought some IMI 308 match for 300.00 plus shipping brand new. The cases are about the same weight as LC brass, but the primer pockets are really tight. If you don't have a bench mounted priming system these are not for you. I used an rcbs priming unit and it was still a workout. weidners reloading in Tenn had them last time I looked.
Anyway, my .308s are the least finicky about brass. I've picked up PMC range brass and done very well with it out to 300 yards and gotten good use out of it. I tend to be a bit more picky about brass with my 6.5s and .25-06. My .308s will pretty much eat anything and spit out a half a minute at my distances so I don't fret about it.
