LaMar: de Haas has nice illustration in his book Bolt Action Rifles showing the different tenons.
Kens: Here's a 93 in 35 Remington. Built this for my son as he likes knock over tin cans with authority (200gr LRN will do that) and he likes aperture sites. I had to fit an extractor blank to this bolt to get it to hold the smaller 35 Rem case. It feeds and shoots well.
