maybe an easy one for gun guys

[Older The Better]

Found this shell the other day and i just noticed instead of a normal nick on the rim what ever fired this .22 left a round hole... whats up with that, is it a specific gun, is it rare? is it common and ive just not happened to find one till now?

.44 Henry rimfire? The Henry had double firing pins. The "H" is for Tyler Henry, inventor of the Henry. The Win. M-1866 used the same ammo. If it's a .22 size, then I'm all wet. Gary

I'm going with an h&r revolver, or any revolver with a round pin on hammer.

Good to know!
My first thought was that the "H" stood for Hornady.

Winchester always used a H Headstamp (Henry) on 22 cases, yours is a 22 Long or Long Rifle case. Every gun maker used a different firing pin shape. One of the common ones.

its is a regular .22 I'm pretty sure just a Winchester but its the first ive seen with a round pin mark. i thought maybe it was rare but it looks like just a sampling bias, i mostly hunt my families land and i guess not many guns with that style of pin have been used. is there a name for that style of mechanism? are there certain guns that use it or is it a pretty broad list?

Many .22 LR revolvers with a transfer bar have round firing pins.

All T/C Contender pistols.

Many Semi-Auto pistols.

I have a Rossi 62 pump .22 with a round firing pin. It's a clone of the Winchester M1890 and M62 pump .22s - that have round firing pins.

The list would be hundreds of .22s over the years.

The "H" definitely stands for "Henry". The caliber is a little uncertain. If the case is the size (diameter) of a .22 rim fire case, then it is a .22. The .44 Henry case is twice the diameter of the .22 rim fire cartridge and looks like a .44 pistol cartridge case with the exception of the center fire primer feature. The round firing pin dent is not that odd and definitely puts a lot of doubt on it being a .44 Henry cartridge in that the original .44 Henry rifle had a DOUBLE firing pin! So there would be TWO firing pin dents. One at the 9 O'clock position and one at 3 O'clock. The .44 Henry caliber Ball & Williams rifle is a possibility but the firing pin impression was a regular "l" strike.

A round firing pin isn't uncommon.I had a few .22s with round firing pins.
