I need to design a Powder Magazine for sure.
I have an embarrassing amount powder and primers. I'm 54 years old so I hope I have many years of shooting left.

Thank you GT I missed it being posted prior to my the question.

I was told to get a complete burn you had to have your pressures up there too.   With my loads running on the low side, (Pressure Trace is giving me pressures identical to a Black powder load) I get some un-burned powder kernels left in the bore, some folks seem to worry about that, to date, including Friday evening, the best groups I have ever shot with the above mentioned cartridges at 500 yards has been with my loads of 5744.  The Lovex isn't quite there yet but I'm working on it.

I've had good success with 5744 in 45-70. Iron sight accuracy of course and if it shoots good I don't worry about the unburned powder. It works very well and burns clean in my newly acquired #5 Rolling Block in 7x57 with 175 gr. cast loads.

H-108 is a very good powder and back when it was being closed out we were getting it straight from Chris Hodgdon for $50.00 an 8# Jug delivered at the time.

Link?

My immediate suspicion is over charge.  Double charge is just possible in the 7.5x55 case I was playing with, and ditto the .30-06.  Blame the powder only to the extent that it's dense, and also that it doesn't flow well in some meters.

Maybe this incident ?

I have several folks that I shoot with that have all kinds of theories about this smokeless and it should never be used!  First off,  Phil is correct  that it doesn't flow well through MOST metering devices and with a low load density and a chance for bridging, it's a process looking for a train wreck - not necessarily a double charge but definitely more than expected- been there once, changed my ways.  I use a Belding and Mull with a load tube that I can actually see the charge.  Even after all the charges are placed I still do a visual inspection before setting a bullet.  I don't use any fillers or cards, someone had a write up about this and similar powders and they had some facts backing their theory, pressure tracking devices and such, it wasn't just hearsay and opinions.
   
I have used it in '06 and 30-40 cases capped with cast bullets, my results for these were marginal, but that was just my experiences.  I know a few folks that have excellent results with it and I haven't beat their scores yet with my alternatives, so that says something.
I also have real strong opinions about some of the folks that reload, they land right next to my opinions of some of the folks that drive 5000# automobiles, they shouldn't.  But my opinions and the law don't always coincide   (short rant - I'm done!).
