I like the old style pin also but the assembly is cumbersome and takes a lot of spring to get it moving while maintaining lock time. I didn't read everything that has been discussed here but I know the tip's profile is very critical. Ask a lot of the guys that have a Zermatt Arms action. Most get cratering and it is due to a radius that is too long, any longer from the tip and I am sure they would be poking holes in primers as well. Cratering and "blanking" is all about flow.
