As always you should check your loads when changing any component. This was shot in a friend’s rifle that is going on a P-dog hunt pretty soon. He was checking his loads after changing to a new batch of primers. This was the first shot on the new primer batch. He was not going to check them and just go with it. I talked him into shooting a few this was the first round. It blew stuff back into his face and also blew something lose in the trigger group and wouldn’t let the sear engage properly. He is okay and glad I had him shoot it. That would have sucked to be on a hunt and have thins happen on the first day of 4.

Oopsy! Good reminder.

Do you know if the load fairly hot?

My dad sent me a picture of the thermometer by his place in GA yesterday, 102F. That's warm enough to make a load somebody worked up when it was cool develop excessive pressure.

No the load was not hot. No signs of pressure or hard bolt lift. the load was developed on a 95 degree day. the powder is not sincitive to weather change. so it was the primer change. It was the same primer just a different lot number.

So in that picture the firing pin penetrated the cap and blow back ensued???
So the cap proud, flush or recessed with base of casing?  It looks flush to slightly proud.
 
Was there any damage to the firing pin?
 
Glad he wasn't hurt!!!

I've got about 100 rounds of loads to test using RL15 for the first time.  I usually shoot with temps below 68F so I've been hesitant to shoot them till ot cools off.  Glad I have waited now!

the primer was set at proper depth. yes blow back did happen and the firing pin was not harmed. it did bust the ejector or the ectractor. it did make the sear not catch right. I get to fix that tonight. He is backing off the load 2 gr and going to work back up. It was a strange thing as it was not a max load by a long shot. they were just shooting good.

Had an ol' guy blow one up at the range yesterday right next to me. Loads were loaded in '75 close to max. He couldn't remember what time of year it was.    Ever heard a 223 sound like a 308.   Had to beat the bolt open an the case was stuck in the bolt. No body hurt but his pride.

Yup. Usually the primer has the least effect. Temp, seating depth, powder, case brand change usually have much more effect than changing primer brand. Small cases are much more sensitive to pressure though and that looks like a 223.
