Uberti rolling block - .22 mag, issues?

[ontgunner]

I'm asking for a buddy of mine who's computer challenged.
He recently bought one of these beauties and we've had it to the range a couple of times.
The issue is a FTF. Initially thought it might be because it was new, and perhaps needed extra cleaning.
It has been noted that it is most prevalent with Winchester ammo.
On the second trip we tried CCI's, Remington's and Winchesters. Ultimately, it seemed the Winchester's were the problem. (IIRC, only 1 FTF with the other ammo... which is still way too many in a single shot).
So, anyone with this gun that's had the same issue, or issues with Winchester ammo (ha, my thread on DynaDuds comes to mind ) ?
Almost forgot... the rim seems to be hit well enough. Though I noticed the pin doesn't hit the very edge of the rim, but about 1/32" inside... if this helps.

take it to a gunsmith and get its headspace checked.Is it possible it's a centerfire .22 hornet?

Smith will be looking at it in a week (when he comes back from hunting).
Fairly sure a .22 mag round would fall right into a hornet chamber... but no, the rifle is brand new and stamped .22 mag.

Where it strikes the rim is as important as how well it strikes the rim.

If the pin is too wide, some of the cases with either a slightly harder alloy, or slightly thicker material will withstand the blow from the pin a little bit more.

Does the pin have a full round profile on the end? Flat? Ball ended? Straight line or wedge shaped?

The gunsmith will, like as not, be looking at the pin for interference , as well as the size and shape of the pin, and the way the tip acts on the case.

Take some of the fired cases with you when you take it in. Duds bother some people (carrying them , that is) but I would take in one or two, as well.

Dont get overly excited about this.
About a year or two ago I was testing sub-calibre adapters (22 WMR) in a 12 gauge shotgun.
I too was using Winchester cheapo brando ammo.
I too had more than a few misfires....so I would blame the ammunition first.

Yes Ontgunner, it does remind me also of the Dynaduds,as you pointed out. And all FTF casings were well struck.
If I was a betting man, I would venture to guess it was probably not the rifle, unless you have a short or defective firing pin, as Trevj pointed out, or a misaligned hammer fall (friction against the action, due to improper alignment of the hammer)
The only else thing I would suggest, would be to check for excessive oil/grease build up, this could on a cooler day, in the right place, could slow down firing pin fall.
Thankfully on a single shot rifle like this, there are few things, that could go wrong.

Good luck...
