About that extra 9mm cylinder....

[rjwinz]

Just shot my New Flattop with the 9mm cylinder, using Winchester white box ammo. Had 1 to 3 misfires every cylinder reload. They occurred with the gun slightly depressed from the horizontal. If I pointed the gun up in the air after the misfire they would fire. If I pointed the gun vertical and then lowered it gently they might fire. There appears to be too much space between cylinder/base of the cartridge and the frame/firing pin. I suppose the problem is that the round seats on the cartridge case and is thus dependent upon that length. Is Winchester white box a standard case length? I didn't have any other ammo with me to compare. Thanks.

It could be a bad cylinder but my bet is the ammo is the issue. Winchester likes to go stupid once in awhile and puts a monster roll crimp on a round that is suppose to headspace on its case mouth. Idiots!!!!!

I'll run some premium ammunition through it and see.

There probably is no need to get premium ammo for it but maybe try some Federal range fodder or something else.

This picture is from several years ago, I still have the offending box of WWB ammo that a friend bought at Wallyworld. He gave it to me as he didn't want it mixed up with some good stuff. I was going to pull the bullets and maybe save the brass if they size okay but just never got around to it.
