Yeck smith bore size

[Don Wilt, 11906]

I recently purchased a Yeck Smith carbine. Does anybody know what bore size they were? I can't even start my .515 down the barrel. Any help is greatly appreciated.

Interesting... all the Yeck Smiths I have encountered are .518".

Don, Are you trying to start the test bullet from the breech or the muzzle? I heard that there was a run of Yeck Smiths made some years ago that had progressive depth rifling, but it was done backwards -- the bore at the breech was tighter than at the muzzle. These had to be relined -- I think I have one of those -- it was relined by Bobby Hoyt. You may have to do the same.

Thanks for all the responses. I wasn't pushing the bullet hard enough, a sized 515 fit. I'm going to try it this afternoon. All this warm weather is getting me ready for the '09 season! :lol:

as far as I know all barrels where 518 and came from Numrich arms
Sam Dobbins help put them togather.

58 Minnie is right, they're all .518", accordingly a .515" will fit but not seal the bore. Another problem that a Yeck Smith can have is an overly long chamber. Put a little modeling clay on the back end of a shell and close the action to see if there is .008 excess headspace. This problem can cause misfires! Otherwise, the Yeck Smith is a good shooter.
