Case Head Exits Rifle

The hammer moved it back into battery, Jim, as you still had the trigger pulled and the sear was disengaged.

Put the full-up/stronger spring back in.

Believe it or not I had a similar problem last week with a S&W Model-19 which had had its mainspring cut down to smooth out the action. Primer setback could then push the hammer to back out enough to allow primer flow right back to/into the firing pin hole and lock up the cylinder on every full-up/40,000psi .357Mag load.

Putting the original mainspring back in solved the problem.

In the Model-19 it was an annoyance. With the rolling block's dependence upon hammer position to lock up the breech, that sounds like a potentially fatal annoyance.

Bright minds think alike. I have come to the same conclusion. I didn't like the heavy RRB spring at all. I think I will rig up a coil spring setup that is adjustable. Frank De Haas, Mr. Single Shot, had a similar setup in one of his rifles. You get the necessary spring strength without the harsh trigger pull. I am a strong fan of light crisp trigger pulls, but not at the expense of my eyes. I was probably a few thousandths of a second from a real disaster. I look funny enough as it is.

I wonder what other problems I have that you guys can solve. This is a neat frum. I thank you all for your input. I bought that first 7mm RRB in Columbus, Mississippi in 1968. I have always regretted selling it.


By the way, I am the guy who built the 22 K-Hornet by cutting and shortening a 91 Mauser receiver (posted several months ago). You guys may remember I was having a problem with split cases fireforming the K-Hornets from Remington Hornet brass. From all your posts, I solved that problem. That K-Hornet is fun to shoot, cheap to shoot, and deadly on cottonmouths in the swamp!

Thanks, everyone.

PS
I have always wanted a Model 19 since I read an article on the Model 19 by Skeeter Skelton (I am old!). I settled for a 3" SS Model 66. My favorite wheel gun is still my $99.00 (new) 1972 Ruger 45 Colt (4 5/8" barrel - originally 7 1/2" but I cut it and never regretted it) in a Troy Mason hand made holster.
