Until now I personally have never had a conversation about 22 cm barrels. Do they get better gas pressure that 16cm barrels?  Wink

I just looked up the .22 Creedmore...That thing is a beast!  Probably best for the smaller dinosaurs like Dilophosaurus or Microceratus, or if you're good at hitting fast moving targets, Compsognathus.  Since they're so small, you might just cause Compsognathus to explode from the hydrostatic shockwave, though...

Is es doing a modified gas system? Imo the 308 had stuck case issues caused by the combo of insufficient extractor surface and earlier than ideal unlocking because of bcg mass and required inertia. Stepping up to 6.5cm, 6cm and even further 22cm with slower burning powders seems like it would make it so much worse. I mean we're at at least rifle length and +2 gas systems with ar type rifles to keep from destroying brass.

thats partially what I want to find out will the brass be in any condition to reload if not I will build one with a longer gas system like I did with my bsf 308 barrel

With the or mdr gas system I'm curious if it would even function reliably much less spit out reusable brass.

You know you're probably looking at 1500-2000 rounds max of accurate barrel life right? I think I've read a handful of places that prs guys toss 6cm barrels at 1800-2000. They probably do have a pretty strict accuracy requirement though. Is chrome lining an option for one off barrels? 22cm would be a good candidate.

all depends how hot you load them Iíve seen some guys who loaded 60 to 80g around the 3100 to 3500 FPS and he got 2500 rounds and he lost about a half moa took it to 3000 before it was not the greatest but yea Iím going to try and find either chromeline or a nitrate coating
