CETME C308 Cast boolit load that cycles
So I have read through a quite a few threads here and none of them seem to come to a similar conclusion. My question is, should I be using a lighter boolit (lee 312-160) or heavier (lee 312-185) which a slower powder or fast powder? I loaded up some test loads today and took it to the range and only had 1 round eject and pick up the next round.
I used 13 and 15gr of unique (didn’t do anything), 32gr of SW AR plus (didn’t do anything) 17 and 23gr of 2400 (23gr had the one round that cycled) these were all with a 185gr cast bullet PC and GC.
I would preferably have a load using the AR plus as I have about 8lbs of that while I only have a lb of the other two. I was using the data listed in the lyman CB handbook.
I know on rifles like the garand you need a heavy boolit to cycle the action to have enough dwell time. While the CETME is roller delayed I have read that it relies on the recoil impulse. I’ve never reloading for a roller delayed rifle so not really sure where I should go to next as far as testing goes. (I also wouldn’t mind a fart load like 13gr red dot if something like that will cycle).
