My buddy got a brand new Remmy 700 5R chambered in 300WM and I handloaded some rounds for it based off info I got here on SH (75.6 gr H1000). Well the gun groups around .3moa but I have yet to fire a round with having to tap the bolt open with a wooden block. SO, I loaded up some slower rounds w/ 70 gr H100, still bolt is stuck hard. After buying some cheap Remighton Core Lokts at Walmart and firing them, STILL, bolt is sticking hard. Could there be a burr in the chamber, or something going on with the lug abutments, or....? Sucks cause these guns have a good reputation everywhere I read, but I'm really not wanting him to send the gun off to Remington just to have them keep it for 6 months during hunting season. Again, this gun has less than 20 rounds down it.
