Smokeless powder

[kel]

do not use smokeless powder!too high a pressure for your barrel.
one shot too many you will be stat,if it helps 777 is cleaner than pyrodex.just soap and water maybe a tooth brush but you will live.no time to be lazy black powder is fun but dirty you must clean your gun and all parts.
as for pellet loads a group of us up here in canada are wondering if the 2nd pre charge affects the barrel(ie two pellets both have primer charge)
any data back would be great.this seems to only affect the barrels of people who use sabolts.the palstic is fouling the in line barrels. good luck
