I'm building a rifle that will be strictly for target shooting and am not interested in pc'ness. In the past I have used single lock bolts in the five or six rifles I've built, but am just wondering if there is a good enough reason for a second bolt at the front end of the lock plate to take the extra time to position everything. One seems alot easier to do but if there's a good reason for a second bolt, I dont mind doing it. The lock is a Kettleman from Jim Chambers.
