Ok. I just got done reading about primer pocket size and wether to use mag primers in BP cartridges, in my case, 32-40 and 45-70. In my 45-70 I seem to get "even" ignition. In my 32-40 with 30 gr. of fffg I notice the ignition seems different. I'm breach seating the bullet and putting a wad in the case mouth. Accuracy seems ok, no fliers, but the report and kick seem to vary. The 30 gr. charge does not fill up the case. Should I be putting a wad down on the powder? Use foam that is long enough to hold the powder back? Don't worry about it? 30 gr. fffg is more accurate than 40. How about magnum primers, would they even out ignition?
