Hard to eject/ primer was out?

[Brianma65]

My buddy was shooting 22/50 with max bullits and mid load CFE223. The cases were very hard to extract( took a lot of pressure on the bolt , to extract. Also the primers were out of the pocket. Any ideas ?

headspace?

 

[stubblejumper]

Perhaps the loads weren't so mild in his rifle?

headspace?

Not sure, he fired off the same recipe before without any issues. Today he had reloads with 4064 and cfe223 . The 4064 worked fine. We're going to check the remaining loads out as soon as we get home.

Cases sticking in the chamber can possibly mean high pressure.
Primers backing out can possibly mean bad headspace coupled with low pressure (not enough pressure to expand the case heads back to the bolt face when improperly headspaced; can cause case head separations).

35.7 g CFE 223 , its in the middle. He's used this previously , with out issues. 3 in a row , I noticed a fair amount of smoke and they appeared to be louder. Possible the COL was to long?

If they are reloads, could the primer be coming out due to a lose primer pocket?

Possible , can we tell if we check remains loads?

Cartridge call for 2.350 OAL and is 2.342.

Hodgdon CFE 223 .224" 2.350" 36.0 3,557 49,300 PSI 39.2 3,855 63,500 PSI

almost 3 full grains of powder difference in 223 cfc & 4064 3 grains more than max will surely make bolt lift hard and blow primers out and your in major over pressures

he only used 35.7 CFE , which is mid range according to our Hormady manual. He didn't just reload both cartridges with the same amount of 2 different powders.

If the cases loaded with imr 4064 showed no issues, then it likely isn't headspace or loose primer pockets.

I would pull a few bullets and double check charge weights on a known good scale. Sticky bearings on a balance beam can cause over charges, a faulty electronic scale can be just as dangerous.

Found the problem. We pulled one apart and weighed the charge. It was 3.2 g over max.The scale is a rCBS 505 scale. I've used it plenty and although I do have to re zero it every time I use it I haven't had any problems. My buddy said he was sure of the charge
, so maybe it got stuck or something .

So it was excessive pressure after all. At least you know what excessive pressure signs look like now.
