Check out this warning I received from a powder testing site when I inquired about 700-X:
I wouldn't pay much attention to them after what was quoted that they said.......
I think it is not responsible of Hodgdon to post reloading information for this, for pistol. Its a terrible, dangerous choice
I fully recommend for intermediate and beginer reloaders, they choose powders like AA#7, or Blue Dot, etc. Because you can't put enough powder in the case to make it super dangerous.
THAT's why we measure powder!
Having good case fill so a double charge would overflow is nice, but not required IMO
Right, AA#7 and Blue Dot......these two are on the slow side for 9mm powder, probably about as slow as is useful in 9mm.
If I was making a recommendation for a beginner reloader in 9mm I would recommend something with a burn rate in here, HP38/W231 would be a good choice for a first powder for a new reloader.
Any powder is dangerous if you use to heavy a charge, faster powders are less forgiving, but to say it is not responsible of Hodgdon to post data for it is unfair.
I'm sure if there was an issue with posted data blowing up guns we would hear about it.
Now if Billy Bob decides the data is "lawyered down" and uses more than is listed, or has poor reloading QC and ends up with a heavier charge than listed charge, then yep there could be issues....
Fast powders in 9mm are best suited for midrange loads IMO, if I wanted the vel that a fast powder at MAX charge would give me I would be tempted to go with a slower powder that would give me that vel and not be at MAX charge....
Red Dot/Promo are both listed as faster than 700X, Titegroup is listed a hair slower but they are close burn speed wise, difference in charges between them of course but burn speed wise probably not that much difference.
I used up a couple lbs of Promo in 9mm with no issues. Did it meter great no, for me say + or - .2gr So if I plan on throwing a charges and am a least .2gr under max to allow for the swing I don't have to worry about it, if I was planning on loading MAX charges with it, it would be wise to weigh every charge which is always a good idea with any powder when loading MAX loads.
