I'm glad it worked for you, but Delin doesnt always work. I'm glad wood worked for you but others have fractured and double wedged it into their barrel. It's a disaster.
Brass always works.
Why would I pick a material that has risk if I can pick a material that has no risk?
I haven't tried it on a rifle, and admittedly didn't even think about it. I could see long piece of delrin haveing too much flex in a long barrel.
My experience was with a thicker short piece.
