In my 12 ga. I load 70 grains 3f in plasic hulls, 1 oz of shot with the nitro and cushion wads needed to make a nice crimp. Sometimes it is 1 1/2 cushions etc. to fill the shell.

I use the same load with 11 gauge wads and megtech brass.

I have even used this same load in my modern 20 ga.

I shoot a lot of skeet and once a month or so I need to get my black powder/hammer gun fix.

The boys at the club are used to it by now. It is just for fun but my scores stays about the same.

Since I also shoot muzzle loading skeet, having the nitro and cushion wads on hand is no big deal.

Unfortunately reloading black powder is about twice what smokless costs. It is now over $8.00 a box.

2- piper,

I had the same problem with PB on really cold days. A noticable difference in velocity.

Real black powder, not the subs, has always worked for me and it always goes off.

I have had some strange issues with the BP subs in my muzzle loading rifles so I do not use them in my cartridge shotguns.

RPr;
The BP subs are made not to have that easy iignition of true BP so they come under different regs & can be sold wherever smokless is sold. An ordinary "Original style" percussian cap will not always under all circumstances give proper ignition to them I understand. While I have not used them extensively I would expect reliable ignition with modern primers as you would use in a shotshell. If Standard LP primers proved to be inadequate you could always switch to Magnum LP.
While I personally am a tradionalist in MLers I know that a lot of those using the modern non-replica MLers use regular shotshell primers & the BP subs with confidence.
