Serious question.Duplex loads work fine. I would only use 10 gr real black when I used to do it and it worked just fine. Will save you a bunch vs 35 grains. Now I order like most and have it delivered and am in the pocess of gathering materials to try my hand at........well you know. Need a few more 25% off coupons for my press and tumbler.
What would happen with a 50/50 mix of real black and a substitute?
Would it ignite better and burn better than straight up T7 or Pyro?
Obviously, you'd want to shake the container really well before metering out your charge.
