Taurus 627 problems, help !

[Patrick1981]

Hello guys, this time I have a serious problem to be solved for a close friend, I hope someone can help me.

To begin with, I want to say that I am a S&W fan and I had not recommended to take a Taurus 627, used in this case.

Unfortunately he bought it.

The revolver is a Taurus 627, cal 357, 7 shots.

To begin the timing is not great, but still acceptable.

Using the original main spring has also had some missfire with CCI primers, but I think the problems are different.

We have found that a drum full of live ammunition, sometimes gets hard to cock the single action in particular.

Instead if I put 7 shells fired the problem of binding is gone.

The cylinder had a little bit endshake, but I know only S&W mechanical and I noticed that the Taurus yoke-cylinder

assembly is not easy to open and contains many more parts.

On web there is not a detailed explanation of how you can do to open yoke-cylinder assembly

or to remove Taurus endshake.

The firing pin (like S&W new style, inside the frame) seems to me that come back well after firing.

I'm thinking if there could be a game of high-low side and that the ammunition with the weight can shift

slightly ratchet position and create problems, with shells fired are not there.

However, the system of centering extractor is like S&W old type with two small central pivots and then perhaps not what ..

Ratchet and hand have no perceptible signs of wear.

Summing up the gun unloaded or loaded with shells seems to runs well..

If there are loads rounds with these problems of cock and missfire.

I attach some pictures, but I'll do better and useful of cylinder, ratchet etc.. in the coming days as soon as I see my friend.

Thank you for your patience.

Sounds like an endshake issue, easy of hard to cock depending on the cylinder ratchet distance from the hand.

[Patrick1981]

With this theory..the hard to cock hammer condition is when the cylinder is back (to me) or front to the barrel?

Thanks Toothguy

You might check to make sure none of the bullets are sticking out the front of the cylinder and rubbing on the back of the barrel.

[Patrick1981]

Toolguy, the bullets are ok, exactly for this thing, before start reloading I give another 3/4 turn down to bullet/crimp die to make the right OAL.

This evening (here now is 2'00 AM) when I going to cinema to see Hand of Watch (I like it really), I think another possible cause..

I remember that the cylinder screw (like S&W new style with a little spring inside and a plunger) maybe was damaged..

When unscrew the screw come out disassembly..well, excusme for my spaghetti english ahah

So..the plunger with the spring is again in the hole, to take it, I rotate the gun and they fall in my hand..

Maybe the screw was broken and in fact it's strange shorter and not perfectly surface at the end..

I have this doubt.. what do you think?

[Patrick1981]

Look at the wrong position of the plunger..

It sounds like both problems, misfires and hard to cock only with unfired ammo could be from high primers on reloaded amunition double check that the primers are seated all the way.

Primers are really deep seated, in first shoot brasses

[DougCarden]

They have lifetime warranties. Send it back for repair. They are notorious for having soft metal and going out of time with a lot of use. Life is too short to mess with it. They will take care of it.....

Good luck,

Doug

that's good, but now I am out of easy answers.
