All of these could be candidates from the looks

http://en.wikipedia.org/wiki/.30_Mauser Used by the Broomhandle Mauser
http://en.wikipedia.org/wiki/7.65x22mm_Parabellum Browning Hi-Power, Ruger P94 and a few others, popular where civilians can't own military calibers
http://en.wikipedia.org/wiki/7.62x25mm_Tokarev Used by the TT-33, a soviet standard-issue military sidearm and the Vz. 52, a Czech standard-issue sidearm... Almost identical to the .30 Mauser

The 7.65x22mm Parabellum casing is 22mm long in total with the other 2 coming in at about 25mm

Pretty much what I have - who would use one of THEM and leave the brass lying around in the wilderness??

What's the overall length of the brass and the rim diameter? .300-221 (the whisper cartridge) has a 9.6mm rim and is 25mm from rim to shoulder with a 35mm overall length. 10mm longer than the tokarev but they look surprisingly similar...

No micrometer but rim dia seems same as 9mm, however it seems the body MAY have a slight taper - i.e. rolling it shows it wants to follow a curved track.

Having searched the interweb I have seemed to be at a loss to the use of this round in any other than in a pistol. (TT33).

Finding one lying around in the "wilderness" only leads me to the conclusion that someone has been using such on a non approved range.

Thde TT33 is a semi auto so the brass would be ejected to the ground during the pistols operation. I know you have shot semi autos, have you always found every piece of brass?

Hope this pistol wasnt being tried out for a criminal purpose.

Good morning to you all.

SD hope the information provided was of assistance.

It always amazes me how my brain pops up with information on all sorts of stuff I didnt know that I knew anything about.

I dont know where the leap came from your original post to me thinking about .30 Mauser and derivatives. It was only a matter of a few minutes from seeing your question to being on the right track.

To the rest of you.

The estate agent came last night. Our house is sold. We have made an offer on another in Tuakau.

Posession date is the 12th of March so we have 4 weeks left to organise the farewell shoot of the Onewhero Gun CLub.

As far as I have been told by Sharron I am not aware of any social functions over the next 4 weeks. So start talking now.

When do you wish to gather. The cottage is empty so if need be there is space to bunk down there for those of you who would wish to stay overnight. Just bring sleeping bags etc.

Lost the BBQ but something can be arranged.

Let me know when you will like to come for a days fun and games and also who is comming.

All you regulars are expected (you know who you are). Anyone else just let me know.

Chris

awesome, i can bring a wolesly, bbq, beer and a box of clays.

I'd prefer it to be later rather than sooner so i can afford some more projectiles/ primers / powders.

Got the rest of February free, but all of March booked out for weddings and crap like that (except the last weekend of March). From now is good. End of this month (27th/28th) would be best, first 3 weeks in March would be impossible.

Might try and pickup one of those mechanical throwers if I get a chance.

**jono035** · 10th February 2010, 09:27

Sunday 21st is the only date that wouldn't work for me. Any time other than that and I'll be free. Might have to get on with my plans for this .303 so I've got something bigger than a .22 to shoot this time.
