I'm Re-loading 40-82, Using IMR4198 and 260gr cast lead projectiles. I've tried loads from 23.5gr-26.0gr with little consistency at 50 yards. I have been shooting through a fenced gateway and I can hear powder hitting the fence and see un-burnt powder on the snow. I suspect the inconsistency comes from the incomplete powder burn. Should I use fill to top the case up? Or should I use magnum primers? Is there something I have missed? Any thoughts would be great.

Try putting 1.5 grains of Dacron as a filler, this keeps the powder down on the primer and really helps with ignition.
Side affect is it does raise pressure up slightly but helps the powder burn more thoroughly.
I have used this in my 45-70 loads for years without fail.
