H4831 M1 load?

I can't imagine the duration of port pressure having much effect, though will admit to some. How much time doe it take for that bullet to get out the barrel after it passes the port. Milliseconds no doubt. I used a load of RL19, not quite as slow, under 168gr bullets, only gave me 2450fps, but it sure was accurate. Wasn't 55gr at peak velocity, but it worked things quite well

I've used powders as slow as RL19 with 168s. Wasn't 55gr, 51 I believe, and it was a fairly accurate load at around 2500fps. Quickload estimated 8500psi port pressure. I can't see the duration being much different in the gas system with a slower powder, there's very little difference in the amount of time before a bullet exits after passing the gasport.

Well, now look what the board has a done, posted one yesterday, came back today and it wasn't there until after I posted again today, sorry for the double, but it should get my idea across.

If I load '06 that is not M1 friendly I put in commercial boxes or plastic reload boxes to segregate it from M1 ammo.
