I have every manual too. But trusted gunsmiths on this site, has warned about the gas system in a 7400. Sure, hornady does not warn about 7400, but I trust this gunsmith and so does many on here.
Luckily I was able to email stalkingbear and he aswered the question. I don't mean to sound rude, but if one does not have experience in something, they are just guessing. Possibly educated guesses, but still guesses. So I appoligize in advance for sounding like I don't want to hear the guesses.
YES, I do have experience loading the BAR. I load for 30-06, 338 Win Mag and 300WSM BAR Safari and a 300WSM ShortTrac.
And why should winchester supreme care? They load to SAAMI spec and could care less
Maybe if you lost the attitude you could learn something. Winchester uses Supreme 780(it's a powder) in their factory Supreme Ammunition. Supreme 780 (it's a powder) has a very slow burn rate compared to most other powders recommended for the 30-06, down there with R-22 (it's a powder as well). Nowhere does Winchester guard against the use of their Supreme Ammo(slow powder) in any semi-auto let alone the BAR.
Now you tell me, what the hell does SAAMI chamber pressure specs have to do with Burn rate and "Port" pressure? Answer, NOTHING! If you know so much about handloading you would know that port pressure and chamber pressure are mutually exclusive. It is possible to have high chamber pressure and low port pressure and vise-verse.
Now I will take your ORDERS and move on, ASS FACE.
