CavTrooper Wrote:Allright, so Im having some problems. My grendel has issues chambering. Its not the ammo, Im using Lapua brass, all trimmed and sized consistently, bullets seated uniformly. I dont think its the magazines, I have 2 CProducts 10 rounders, one needed feedlip fixing, the other ran smooth right from the jump, both seem to feed fine. Im thinking it could be either a bolt lug problem. The reason I think this is because it also locks up pretty tight sometimes and is a pain in the a** to pull the charging handle back and extract a round. Im mostly concerned because I have been using this rifle for hunting and even though I havent come across the problem yet, Im worried about needing a quick second or third shot and having a round go off out of battery. This issues prevents me from taking my Grendel out more often and want to get it figured out now that Ive got some property thats overrun with hogs and free reign to hunt em. Anyone else have a similar issue? Howd you fix it?
CT:
Only times this has happened is if I seated the bullets too long.
Try this. Clean the chamber using a M-16 chamber brush, hose it out with carb cleaner and dry. Put some lube on the extractor as well as through those two lube holes in the bolt carrier. No, lets not re-enact a Army range where guys squirt CLP all over the outside of the bolt carrier using a spray bottle. Get the stuff inside of the bolt carrier on to the bolt and gas rings.
BTW -- check your gas rings while you are at it. Grendels go through gas rings pretty quickly.
