[QUOTE="uncleB, post: 137655, member: 4679"] [ QUOTE ] I've never mixed powders nor am I hear to say if its right or wrong. But, goodgrouper, your quote from the guy at hodgdon [ QUOTE ] Hodgdon: Well, in our lots, we have plus or minus 3% to 6% variation in burn rate between lots even with the best components and manufacturing processes. So if you mix two powders and one is on the high side of 6% and the other was on the low side of 6%, your new mixed powder could be changed as much as 12%! [/ QUOTE ] +6 averaged with -6 = 0 In other words it is impossible for the mix to exceed the + or - 6% standard deviation. The guy you spoke to at Hodgdon would never tell you to mix powders even if he thought it was ok because of liability issues, so I put almost no stock in what they told you. Lastly, I believe temperature, elevation, humidity, and most of all wind are bigger variables to contend with than mixing 2 lots of the same powder. I also noticed that you mentioned in other posts that you use reloader powders. Isn't that one of the most temp sensitive powders? [/ QUOTE ] roll-yur-own, WOW!!!!!!!!!!!! it is very impressive to post such a statement and be so wrong on every point. you bailed out catshooter [/QUOTE]
