My brother used 27gr ,AA1680 for 223 55gr fmj 😳

You read it correctly. My brother thought he had CFE 223 in his chargemaster when it actually had, A 1680 from reloading blackout, It didn't go well. He pulled the trigger ( bolt action gun) an he said he felt stuff hit him in the face. The bolt felt like it was welded in there. He didn't chalk it up to be a reloading issue so he dropped a round into a Ar. Well that didn't go well either. To add to the pressure problem a surpressor was attached. The mag blew out and apart and the BCG was like it was welded in there. Had to believe, He was totally fine. My question is, does anyone have the software to figure out what that pressure was and I'd love to know what that velocity comes out to be BTW he got the bolts out. The brass was molded into the bolt like it was poured into it. Bent the extractor.
I told him my rule is always when finished, dump the powder back into the container. Never have any other powder even near the bench that your not currently using.

I would say that I'd just test it, but it's really hard on the transducers going over 80,000psi. Not going to risk it on this one. I'd guess well in excess of 100,000psi if you've got peanut butter brass. Glad no one got seriously hurt.

Led zep,, I surprised the upper stayed together. He's very lucky. Now both guns are going to need a whole Lotta love

Always empty the Chargemaster.

I keep powder in the Lee powder measure but it’s always Benchmark.

Glad he’s okay.

Wow that’s wild and I’m glad he’s ok.

I made labels put them on magnetic tape for my powder measures. Can’t be too careful when it can be awhile between reloading sessions.

I just added some white metal tape so I can write the charge weight with a dry erase marker.

I may have missed the caliber and bullet weight. Gordon's Reloading tool is free download. I can plug in the specs if you post them.

This is .223 with 27 grains of 1680 and 55 grain bullet. figure about 111K PSI and 3700+fps?
