Myself and many others have been using 777 for some time with no problems without seeking reproofing.
Just bear in mind that 777 is about 25% more powerful than black powder so adjust your load accordingly.
My load I like by VOLUME with my .44 Remington is 24g of 777. .36 Colt 12g 777, however recently I have gone over to using Pyrodex P in the Colt 15g of the Pyrodex gives the best results - just my findings..
Pyrodex P same by volume as B/P.
Why not try Pyrodex P? Much cheaper than 777.
Neil, as has already been said ther's no need for a re-proof to use any of the BP substitutes (Triple 7, Pyrodex) and with Triple 7 cut back on the load (in comparison to BP).
I use 15 grains by weight of Triple 7 fffg in my .44 to good effect.
I do everything by weight 'cause I can't get my head around volume measurements and I'm used to weight for my centrefire reloading.
Hodgdons say reduce load by 15% by volume for equiv to BP.
Its a bit unscientific as a comparison, 777 burns faster and breech pressures are slightly higher but still well within spec for use in BP firearms.
I am using 12gr by vol (17gr by wt) in my 44 with a 200gr conical but I have had better in the past with higher load so still have some work to do. Going to increase a bit and hope for a flatter trajectory. The lighter load worked well with a lighter round ball but I was wary of the increased pressure with a heavier bullet.
I think its important that anyone considering trying m/l does not see it as some sort of black art, its not its easy and fun. It is no more technical than reloading cartridges. Just a case of finding the right powder and bullet combination to suit your shooting and your own gun.
