Many thanks to both of you guys.
Your probably right about the remaining fouling and crud in the barrel.
I call myself cleaning itreally goodat the end of a shooting session.
But I've noticed sometimes when loading, more so with a sabot it will
feeltight in spots on the way down. The reason I thoughtthe rifling
may be effected is when I'm pushing the projectile down the bore I can
feel it turning with the riflingthrough the ramrod til I get about 8" off
the bottom. Then it seems to go straight down. I'll give it another good
cleaning now that I have a good recipe to follow.

I missed a doe at 50 yards with it 3 days ago. I only got to hunt 2 days
out of our 2 week season due to work and home chores etc... Needless
to say I was more thanheartbroken when the shot didn't hit home. I had
shot it on paper about a week before and hitting a pie plate group at 50
yards with a stray about every third or fourth shot. After the missed doe,
I backed off to 75 yards and it rarely ever hit the Outers 100yrd smallbore
target at all.
