Cylinder throat issue on 629, maybe

[500 Magnum Nut]

Never will a jacketed round touch this gun. This gun is a 629-5 btw.

IF reaming is required I don't see I should need to ream to more than .4295 or .430", assuming my measurements pan out.

I am making several slugs to send to a person with a V-anvil micrometer. I will also acquire my own micrometer and check the cylinder throats (I slugged them all last night), I will also get those pin gauges you mention to double check.

Check ebay in the machine area. I bet for 75 bucks or less you can get quite a nice set of plugs from .250 to .500

What's nice with the plugs, they either go or they don't.

Sometimes you encounter old revolvers that are stamped 1-6 on the chambers. That's because sometimes one chamber won't group as well as others so the shooter can omit the ill shooting chamber for target shooting. If you would measure that ill shooting chamber and throat, you will find it to be .001 or larger than the others.

Buy pin gauges ,you only need a couple , that takes the guess work out of checking cylinder throats.

I'm thinking of sending the gun to the local S&W gunsmith here in Finland and let him check & ream it for me.

I did check the slugs with a micrometer I bought and the chambers seem to be around .429" - .4291" so reaming to .430 is probably the best solution. The smith says he has an adjustable reamer so he can do it to whatever specification I desire then.

(The picture sure looked like a -1 or a no dash to me, so I figured that it had all ready large throats. No offense, All I see is typed messages on a monitor. I don't know you or your background. Some people can't measure anything accurately and I assumed it to be an older gun with the automatically large throats.)

No offense taken, you are trying to help me, after all
