[arcticap]

I know that my barrel accumulates some residue in the throat.
I haven't swabbed because I don't bring along the items to swab with.
It's not really critical because I shoot at fairly short range.
But it wouldn't hurt to try swabbing to see if the performance improves.
Every gun will accumulate residue differently depending on the conditions and the powder used.
I've been meaning to try swabbing since it's very easy to do and I load off the frame anyway.
The wads themselves could cause some erratic results too.
You never know unless they've been tested extensively in your gun and with your loads.
I've tried Cabela's lubed wads and don't really care to use them.
I use home made over powder cards instead and I noticed the difference.
