After my Ruger Redhawk Super Alaskan came back from the custom shop, it no longer reliably fires 454 Casull, even after replacing the "custom" one w. a stock replacement one from Wolff.

Does anyone know of a custom maker who can make a stronger one for me? Wolff will not, apparently.

Thank You,
Brad

Warning smart ass comment to follow:

How about the "Custom" shop that dicked it up in the first place?

While holding the hammer back at full cock, pull the trigger and check to be sure the the T-bar is fully covering the firing pin and that the there isn't a chamfer on the front side along the top edge that may also be reduceing contact area.
If you have the measuring tools you should also measure your firing pin protusion. You'll want .050" to .060"; to measure this you need to ease the hammer back enough to clear the T-bar, then pull the trigger to raise the T_bar under the hammer, lower the hammer against the T-bar so it pushes the firing pin out of the recoil sheild. As you will have the cylinder open you may need to pull the cylinder release lever out with your finger nail so the hammer can be retracted.

The custom shop says it's fine w. federal and winchester ammo (which, as far as I've tested it, it is... and that's their response... They had it for ~ year, and I'm not inclined to let them have it back -- aside from the spring, the work was excellent, however...)

I will check the firing pin protrusion -- it fires 45 oolt just fine -- does that eliminate the firing pin issue?

Sounds like they "over tuned" it. The .454 uses small rifle primers and as such requires a fair bit more impact than a standard large pistol primer as used in a .45Colt, the data on how much more is out in my shop and I'll look it up latter.

Measure the firng pin protusion and get a factory hammer spring. Light springs work fine for playing around, but the .454 needs the heavy hit of a factory spring.

I've already switched back to the original poundage spring, at least according to Wolff (14#s) I'm going to try and order one from Ruger as well, in case it's more powerful.
