So yeah.. Nearly new Palmetto built upper, PSA lower that I assembled. Dillon case gauge. No evidence that the shoulder OR body is wedging in the chamber. The round drops free from case gauge AND chamber. Case gauge is a true free I turn over and out it comes. Chamber it needs a gentle tap on the side of the upper. Anyway, I can take bolt carrier all assembled minus firing pin, drop a round in a mag and let it go home. Upon trying to eject the unspent round it won't release. Last night I went out for Yotes and ended up needing to use my Henry due to this issue. First round in I wanted to check for function before shooting and it wouldn't eject. Bullet info: Hand loads with 55gr soft points. Cases trimmed to spec, sized in a RCBS small base die. Shell holder hits base of die when sizing. Full length. I cannot for the life of me figure out what's causing the issue. When chamber is empty the bolt opens and closes perfectly. No problems whatsoever. Add a round and all hell breaks loose. I've swapped BCG's from my other rifle and same issue. Same thing in other rifle as well. Damnit.. As I've been writing this I was going different things trying to find a solution. I cracked open a 1/2 case I had lying around for emergencies and a 5.56 round chambered and ejected fine. I mean what the hell? It's not like this is my first rodeo... Gun or hand load issue? As a side note on the dies: I can get cases stuck very easily inside this die if there is too much lube or the obvious not enough. In 250 rounds I've had 4. I re examined the die to shell holder and I could lower the die more but currently they touch and slight upward pressure is exerted and the arm doesn't max out at the top when raised against. 0 gap between. Probably -.05 or more. Your thoughts?
