Mr. Zediker is correct in his statements as you quote him however he is referring to high pressure high velocity jacketed bullet loads. This thread is concerned with cast bullets of light to heavy weight at a considerable less pressure than the 55-60,000 psi loads Mr. Zediker refers to. The very reason to use slow burning powders in cast loads to keep the port pressure at a functional level is explained very well by Mr. Zediker. You however are apparently misconstruing what he says. You also are misconstruing your experience with an M1 with what happens with a M1A/M14 system. You are essentially comparing apples to oranges.
FWIW; my first experience with an M14 was in basic training in '64, I qualified Expert. My training with M14s and m14E2s continued through infantry training and I used one for a while in Viet Nam. When I say "used one" I don't mean I was issued one and just carried it around either...I actually "used" it. I continued with competition using military M14s and my own M1As. I made Master HP classification with one shooting over the real course not a reduced course. I also made Master Classification with one at long range HP (600-1000 yards). I also manage a state championship in LE competition with an M1A and I also was a state short and long range IPSC champion with one. I have given combat instruction to US soldiers and foreign soldiers on the M14. I have built many match rifles, rack grade rifles and M14A1s over the years. I first reloaded for the M14/M1a in '69 and have loaded tens of thousands of round since then. My first cast bullet loads for the M1A and m14 were in '76 and I've shot thousands of cast bullet loads through numerous M1A/M14s since then. I still own two M1As, both rebuilt because I couldn't count the number of M1A/M14 barrels I've shot out. Now that may not make me an "expert' as Mr. Zediker is because I do not post over on that forum but then there are many forums I do not post on. I do not claim to be an "expert" here but I do think I know what I am talking about in this instance. Attached are a couple pictures of me with M1A/M14s over the years.
If you pay attention to Bruce, who has done his homework on loading cast bullets in the M1A, you just might learn something that Mr. Zediker might not know.
