Cooper firing pin

[rider]

I started having misfires while shooting PD's today with the model 38 20VT. I inspected the primer and discovered that there was very little evidence of a pin strike. Thought about it for a while and remembered that I had the same problem with the model 38 in 17 AH several years ago. I tightened the pin and solved the issue for a while. Then it started misfiring again. Again the firing had backed out. Have you gentleman had this or similar issues with the model 38?

I had this problem with my Model 38 20VT. A little Loctite on the screw will keep it in place until you want to remove it. Use the blue Loctite so you can disassemble the bolt in the future. If the firing pin turns when you tighten the screw then snug the little set screw on the cocking piece (inside the hole on the tab of the cocking piece) to prevent the firing pin from turning so you can get the screw very tight.

HTH.

Lynn:
Kinda wondered if you hadn't gone "home" this weekend.
IF you don't have any Loctite, come by, I have a couple
bottles.

Hope your folks are doing ok, tell 'em hello even though they
don't know me.

Got that pipe cleaned up and was going to turn the disc to fit but, the
jaws on the lathe won't open quite far enough. Always something
huh?
Take care and don't get snake bit!

George I'll call you this evening.
Harold, I am using Rem. 7 1/2. I have not had any problems with these primers igniting in any number of small rifle cases.
The firing pin "screws" into place and over time it backs out. I should have diagnosed the problem at the last range session as the groups were at least twice as large as normal. "Another valid excuse!,"
