I'm trying to work up a load for a trapdoor
My current components are:
405 grain hollow base, round nose bullet
nickel star line cases
Federal magnum primers
Hodgden Triple 7 FF
My problem is Triple 7 is not supposed to be compressed, yet the recommended (starting) load is 60 grains for a 405 and that much powder would be a heavy compressed load. To load the case to the proper "full but not compressed" spec that Triple 7 calls for, I would only be using 45 grains and even less if I use a card.
Is 45 grains of Trip7 by volume enough umph to get a 405 grain bullet down the tube of a trapdoor and break the paper 100+ yards out?
