PaPoints ,I use a 1" copper booper for all my percussion, I am not a very good at pressure flaking for thinning so I tend to use percusion to do all my thinning, I have started using a small 1/2" bopper for my final thinning and this is workin real well for me when preforms are thin and getting flat, Hope that made some sence

. Setting up isolated platforms also has helped. I'm doing alot more prep work instead of smashing and bashing
