Hi everybody, the base pin on my Herters 401 Powermag jumped out while shooting the other day.
I was shooting a Lyman 244 with 20gns of 296 for about 1371fps.
The base pin does have quite abit of movement.
This is it fully forward with the latch in place.
It looks like there is not very much of the latch protruding into the base pin hole.
I took the latch apart and stretched the spring a little bit, but I don't think that this will cure the problem.
The latch measures .204". I'm thinking about taking an end mill and making the pocket deeper so the latch will protrude more into the base pin hole.
I don't want to mess the gun up.
Any thoughts?
Don't shoot such heavy loads in it, lol...
