Walt, when reloading for pistol or rifle the pressures are much higher with very little powder. Changing the load by a couple of tenths can make a big difference and be even dangerous. With black powder even 30 or 40grs wouldn't be dangerous. With shotgun a grain or two will up pressure and velocity, but if you're loading at the low pressure end, it won't make a big or dangerous difference. I have manuals from all the powder manufactures I got 7 or 8 years ago at state trap shoots. They still hand them out and I find it much easier to use them than go on the internet and type stuff in for a load. It's much easier to compare different loads and what they do. With 15grs of 700X and a 24gram load [about 11 BB's less then 7/8oz] you can get 1100fps and 5300psi. That's with a CB-1100 wad [1oz]. 16grs is 1200/6300psi, and 17grs is 1250fps/7200psi. All those loads are safe, low pressure loads. So you can see we have a little lee way, even if you screw up and get a extra grain or two of powder. Other good powders are Red Dot or Promo [ both the same for data ] , Green Dot, or American Select. They're all Alliant powders and seem available. The Hodgdon powders seem harder to come by. Hope this helps. Paul
