I have never used Ramshot powders (or Rex powders) for one simple reason.....I could never find any reloading data for them!
There is one store in my area that carries Ramshot....but they don't give away (or even HAVE) complimentary reloading data; since they also carry Alliant, Hodgdon, and Winchester powders, guess what I spend my money on?
I've used those powders for years, and I
know what I can do with those powders. I remember back a gazillion years ago, when I first started reloading,
ALL the powder manufacturers gave away complimentary loading pamphlets...you didn't even have to buy their products to get them. You could take them home, look them over, and decide what you wanted to try, and they had literally hundreds of loads per data; not just a handful like I saw on Ramshot's website.
Prices may be good, but I've spent years working up loads for my various handguns/rifles/shotguns with the other guys powders. I don't think I will be switching now, unless I can't get what I need. I think if Ramshot (and maybe even Vithavouri) would have put out more
printed data, and made it freely available, they might have more of a following than what they do.
Just my 2 cents, FWIW........
