Re: Is the powder charge weight the same?
depends.... what's the case capacity on the dull brass vs the shiny... either way, it won't shoot the same

Re: Is the powder charge weight the same?
The powder charge is the same as well as the case volume.
Because of the cases being highly polished the powder stacks up tighter.
Either of the two cases are still a compressed load.
Do you still think they will push different?

Maybe...and I say that because crunching kernals chances breaking the kernals, which alters the burn characteristics from what is designed into the powder.
And the degree of which is out of your emmediate control from case to case.
I avoid compressed loads like the plague, for THAT reason........

Re: Is the powder charge weight the same?
Lot's of people think compressed loads are just fine, but when I R&D a load via OCW it yeilds a load that tunes the exit of the bullet to a point that only a few thousandths of an inch of seating depth will make a difference to the load. The load is inherently dependent, therefore, on a range of powder weights that give the same results...that being usually a half grain above and a half grain below the OCW charge.
This is completely within my control at the bench and gives me a specific result as it pertains to the burn rate/characteristic of the powder. Taking a chance on changing that in an unpredictable way by possibly compromising the burn rate/characteristic by compressing a load is just not in my best interest.
I'll just move on to a faster powder that yields a better load density for my use.........

Re: Is the powder charge weight the same?
I'm not getting this? Are you saying that your stainless steel polished cases all have the same internal capacity, exactly? And, when you load the cases, the powder stacks better and there is no need for compression? By the way, are we looking at fireformed Ackley cases? Kinda looks like it, but if we are supposed to associate the jug of powder with the cases shown, you are being a little too mysterious for me? What's your point? BB
edit: rereading, I see the statement says that they both need compression, my mistake.
But. I get the feeling that you don't need answers, you already know the answers. To me it sounded a little sarcastic to tell trip, "thanks for the help" when he didn't do a heck of a lot? In other words, what he said had no value. Now, is it just me, or why do I feel this way? Let's hear it. Please.
