Yeah, I understand what you mean. They showed us that with the M14 with the trap open on the buttplate. I have tried that with the schuetzens in my buddies collection, a Zischang, a Berg,Schoyen and with my larger than average arms it is very tight to downright impossible to use. I just wonder what pattern buttplate would be the biggest. I like the ones with 2 fully developed prongs but I suppose looks might have to play second fiddle to practicality.I guess I'm asking what buttlplate allows the most room. I have a nearly finished buttstock for a Ballard and a hiwall in factory schuetzen style and I have access to pattern making and casting facilities to modify a buttplate to fit me and also fit the factory style inletting if need be.
