Hi gents, it has been a LONG time since Ive been on here. A while back I acquired a .22wmr/410 barrel off eBay in fanatastic condition. I knew it was from the same era as my .22lr/20 J-DL, so I knew it would fit.
And it does, perfectly. The problem is the firing pin strikes close to the center of the .22 wmr case, not near the edge. I guess Im guilty of assuming that because the radius of the Magnum isn't THAT much bigger than the long rifle, that it would strike and fire. Not so much.
The shotgun fires fine.
Has anyone else encountered this? Are the firing pins on .22 mag frames really aligned differently than on long rifle guns???
More importantly, does anyone have a simple idea for overcoming it? I'd love to be able to shoot 4 different rounds from one gun...
Chris

Wow...i just noticed my status is "rank stranger"...on this "new" forum I joined in 2012.
I remember when CAS still had it on the old platform too!
And I'm a rank stranger.
😔 How soon we are forgotten...

Have you placed the two barrels (.22wmr/410 and .22lr/20) side by side to check their barrel centerline alignment? It is possible that the rifle barrel centerlines do not line up.

That's dedinitely the case. Just more so than I would have though, given the case heads are only a little different.
I guess at this point it's reallg just a matter of whether anyone has rigged a work around...maybe some sort of small extension piece that the firing pin coild strike and it would emgage the case rim??
Hoping for ideas.

sentry44, I need to re-clarify what I said earlier.
The shotgun barrel (center fired) centerlines must line up. but the .22 barrel (rim fired) centerlines should not - as explained below.
Since you said that both shot gun barrels fire, then the 20ga and .410 shell's center fired primers must be on (or very close) the same centerline in order for the shotgun shells to fire.
Since the rim fire (.22lr and .22 WRM) rounds need to have their rims hit by the firing pin to fire then their centerlines should not line up due to their size (diameter) difference. Either the top or bottom of their respective rims must line up to both fire in the same receiver. This is the case in my convertible Ruger Single Six revolver. When comparing the two cylinders, the lower rim of the .22lr round lines up with the lower rim of the .22 mag round, as this is where the firing pin strikes these rounds. Their lower rims are the same distance from the centerline of the cylinder center pin. Since the diameter of the .22 mag is larger then the top of the .22 mag rim must be further from the centerline of the cylinder center pin than the top of the .22lr rim - which it is.
So, now line up the centerline of the shotgun barrels and then look to see if either the top or bottom rims of the .22lr and the .22 WRM line up. It not, then if one of the rifle barrels fires, then the other will not fire.
I hope that I have explained this correctly. So for any confusion earlier.
