txhunter58, no that is not what I mean; most all subs require some seating force the important thing is to get it the same all the time, I have never had a miss or hang fire with it, but to shoot with one hole accuracy at 100yds it takes a certain tightness of sabot and to be firmly seated on the powder.

frontier gander, you are right, first off it is not smokeless it does smoke and it is not made from either of the two basic components used to make smokeless, I do believe it might be progressive and it does have quite a bit more potential enegry than the othe subs except maybe 777-FFF which is close to equal, according to the strain gage the pressure is only a bit more than Pyrodex and less than 777 by around 5-10 percent.
I am thinking of shooting it in my Renagade they say not but thats likely because of possable ignition problems with a mag large rifle in one of those old screw top fireing pin nipples it worked fine for a few test shots. Lee
