Interesting that you all like Reloader 7. I had poor results with it in .45-70, after reading
about how well it shoots. After dozens of different loads with it, none producing anything
better than mediocre to poor groups (jbullets, Speer and Rem 405s, Horn 350s and Sierra 300s) it happened.
Finally, on one load had the only 'fizzles' I have ever seen. Pop and fizz at
hammer drop (Marlin GG) and when you open the action, the case comes out smoking a
bit and dumping scorched powder in the action. Dumping out the case and a glob of
partially melted, scorched powder as big as a little finger tip falls out. Bullet is about 1" or
so into barrel. It did this twice on me. On the first one, I took it as some sort of a wierd
loading error. The second time, I figured it was the powder/case volume/primer/etc combo
and stopped doing it.
No - the powder is new and dry, stored in an oak cabinet in a cool, dry basement with all my other
powders. Never had anything like this before or since, but stopped using it in .45-70, and
when that pound is done, no more getting bought. I found that W748 will make superb
groups, great velocity and low pressures in .45-70, so not going back. Same tray of primers
with other powders, same day, did normal good work. I can show you pix of any number of
3-7 inch groups with RL7 when W748 will make round 1.5" groups with the same bullets.
Fluke? Maybe, but life is short and there are too many powders out there that have never
done that to me to have the slightest inclination to try again. I went back just now and
reviewed the photos, too. Used Fed 215M magnum match primers. No weak flame
there.
I have no doubt that you have all had excellent results, not questioning that in any way,
shape or form. Just that not everyone has excellent results with it.
Similar strange story with me and Varget. No problems but never one single "great"
group in a lot of trying. Finally stopped trying after 4064 beat it to death dozens and
dozens of times, when other folks are getting their best results with Varget.
