Some of my best groups have been made with JSG. Used JSG for hunting for about three years. The second longest shot i ever made on an animal was with JSG: Killed a sow at a measured 192 yards. JSG has some peculiar traits. It likes a tight fitting sabot seated very hard on the powder: Lean on the ramrod until you can feel the powder compress.

Started using Goex Pinnacle a couple years ago but still use some JSG from time to time. Pinnacle is made by the folks who make JSG-American Pioneer Powder. Pinnacle is more powerful that JSG.

It is really nice to be able to fire a muzzleloader 10 or more times without swabbing between shots. It is also nice to be able to get the breech plug out easily. JSG and Pinnacle allow a shooter to do both.
