Endshake corrected!

Bob Wright · February 19, 2013, 06:23 PM

This Hy Hunter single action had an excessive amount of cylinder endshake.

So I ordered a new cylinder bushing from Numrich/Gun Parts Corp. last week. It arrived in today's mail, so I hied out to the shop and replaced it. It required a little fitting, but I had it in place in about five minutes. Now all endshake is gone.

Can you provide more explanation? I have a Ruger Blackhawk in .357 Mag (old model with the conversion, I know, but I bought it on the cheap) that has a minor amount of endshake. It isn't anything I consider problematic, but I load it up with the most powerful ammo I can find (Double Tap and Buffalo Bore) for use in the woods. I wouldn't mind correcting what endshake there is if the solution is easy and cheap and might pevent any further degradation.

Rugers don't have cylinder bushings. Bob's problem appears to be solved, but this is a case where correcting one problem, endshake, might create others, like excess headspace or excess barrel/cylinder gap.

A perceptible amount of endshake is common and no cause for concern unless it becomes excessive. What is excessive? I can't tell without handling the gun. But if I had a Ruger that I felt had excessive endshake, I would return it to Ruger, not use a local gunsmith or try a DIY fix.

Of course it doesn't help to fire "the most powerful ammo I can find" on anything like a steady basis. Sometimes I wish guns had a "red line" like the tach on cars so people would know that their hot loads WILL destroy the gun and sooner, not later.

I don't fire that ammo on a regular basis. But I fire it often enough to get used to the recoil and to make sure it hits close to point of aim. It's the most powerful handgun I have and around here, I don't want to skimp on the power when I step off my porch.

It really isn't that much endshake (the width of a sheet or two of printer paper I guess). Just curious if it was something that needed looking into.

Rugers, as has been pointed out, have no cylinder bushing. However, Powers Customs, I believe, make shims to reduce endshake.

If your gun is firing O.K. now, shims would correct it without any problem. But I would address the issue. Continued battering will accelerate the problem.
