It sort of looks like the gas check was extruding around the pusher stem. I’ve seated .22 checks on powder coated bullets in a lubrisizer, it worked well - I just didn’t pressurize the lube.
Tim, I got to digging around and found around 30 of the Lee bullets. They are powder coated and gas checked. If you don't have any aluminum checks I can send these to you.
I dont bother gas checking these ones, 2275 fps with 15.5gr of IMR 4198 or acc 1680. I have mag dumped 150 in a row with my AM-15 and dont see any fouling. I do check my 7.62x39, 30-30 and 6.5CM casts, after hand tumbling powder I press on gc then stack for baking.
I will have to try powder coating after gas checks. I wasn't having any luck with load workup on cast 55gr using lee mold... H335 powder and I could barely touch 6-8moa at the best. I haven't touched it in a while because of it. Ended up getting a good deal on 55gr fmj bullets so I just load them for plinking instead of casting.
best group i have got with the lee 55gr was with 25.4gr of imr 4350 in my savage 223 bolt gun, averaged 1.7in at 100yds at around 2500fps, non gas checked just powder coated.
@@pcbulletempire9872 I'm running .226 without the gas check . With the 75 gr bullet I'm using now in a 1-7 twist barrel I've got a 3/8 " group at 50 . It's a flat base bullet .
My fingers are getting fatter every year. Those little devils must be hard to handle. I'm still not sure the advantage of gas-checks but they sure look cool.
