The 22 creedmoor thread

Anyone running the Alpha SRP with 450s still seeing hang fires in the cold, even though they have the larger flash holes (0.080) relative to other brands SRP brass?

I've had a hang fire happen twice with Alpha SRP and CCI 450. This was with Varget and the 62 gr ELDVT while working up a load last summer. It was odd - hear the firing pin drop, then split second later, the cartridge fired.

Only happened while doing load development and at the lower end of the charges I was testing (which were plenty full). Did not happen at all during the winter months when hunting predators.

I did when I had a 22 creed barrel.

Damn thats crazy ive got several hundred rounds on this brass an never had a hang fire. I run 39.2 of Varget with 75 eldms. I did ladder testing with a bunch of different powder an never had an issue.

Definitely weird. Only time it’s happened. I’m a good 150+ rounds past that with the same combo and no issues. Might go back the LRP brass once l retire this batch of the SRP.

Alpha srp brass been good for me. Healthy dose of N555(slower burning) with cci450 been good down to single digits, fired prob 20-25, rounds last winter in -10° F, no hang fires.

Edit#
Will also add I tested heavy charges of rl26 with cci450 2 winters back in alpha srp brass in 22cm and 65cm, no issues in negative temps.

I know with the LRP you'll see about 20fps more idk if you'll need to reduce charge or not. I went with SRP cause primers were harder to come across at the time I got over 4,000 of the 450s so I'll stick with them lol.
