[QUOTE="RustyRick, post: 909243, member: 69572"] As I look at my supply of powder, my loading manuals, my caliber and a burn rate chart I find one missing bit of information. For example. How much slower is IMR 4831 than Hodgen 4831. Or how much faster is H4350 than H380. I phone Hodgen to day and I understand the difficulties in objectively rating a powder. However I think (over simplified I'm sure) that SAAMI should do a spread sheet and index the middle or average burn rate at 100. And then rate each powder as a percentage either over or under. Then one would be able to experiment with other powders with some degree of foundation and fudge factor. But it would also answer why in any given manual you see limited number of powders recommended when you know others would work too. Just wondering ....:cool: [/QUOTE]
