I load and reload 44 Remington/Colt C.F. with a 248 Grn heeled, outside lubed bullet. I use Bore Butter as an external lube for all my cartridges. I also use some home made lube sent to me by the Remington Kid Last year. it is good stuff too.
I use 4D, rcbs, lee, and a couple others to load 44 Rem/Colt, 44-40 Win. and others with Bp and have never had a problem. I do use a lee plastic dippers and some I have made from old brass. I don't own a progressive loader, just an RCBS rock Crusher. I also have pulled over 500 rounds of BP to retrieve the BP, the bullets, or the brass, all with a kinetic puller that happens to be very hard plastic and aluminum shaft.
I don't hold with the static electricity setting off BP. I have seen the video of the attempts to set off BP with high voltage. Didn't happen.
I was taught that it takes a FLAME to set it off, this by a fire Captain that just happened to be president of the NMLRA at the time. He told me that you could have BP an inch deep all over your garage floor where the water heater is and unless you kicked the BP into the flame, it'd never go up. Not so with Gasoline (goes on the fumes)or Motor Oil dripping onto a bag of fertilizer, both will burn you outta your house.
