My bad NCHawkeye.

The TC noted on my target stands for Table Cloth, not Thompson Center.

About two years ago I bought a four foot by eight foot table cloth at a thrift store which has a very tight weave and turned out to be perfect patch material. I cut a LARGE supply of patches from that sucker and use them in several guns.

For a while I was writing "table cloth patch" on my targets, but soon got tired of that and switched to the "TC" abbreviation.

I don't lube my patches until the day of a range session, or sometimes the night before.
