I have a high wall in 45-70 and use Brent's bore gophers. I bought one of the great rods from Sycamore station to push them through.
Recently I have been affected with TDS (trapdoor derangement syndrome). They are a blast to shoot, but, you guys know that.
When I shoot the high wall I put a bucket in front of the rifle. I can push a gopher and patch down the bore from the rear. It all ends up in the bucket and gets cleaned up at home.
With a trapdoor I can not use this method. The action keeps me from pushing with a rod from the rear. This means I have to pull the rifle off of the line to clean the bore.
Most of you guys are smarter that me (I live in California that's how dumb I am), have you worked out a way around this problem?
