damm I looked at that add 3 times thanks for the link. I wonder what one will give the best accuracy with the surpluss ammo???? or if there is a differance. what are the advantages of a 4 grove over a 2???
You posted as I was logging in for work.
On another note 1biggun, there also are chrome lined tt barrels out there. would be nice for a simple blow back toy.

All of the surplus 7.62x25 that I have measured was 308 area but if you want to try a looser bore there is the vickers 303 barrels omega has new for $50 is not that bad. I have a deep dark desire of making one of them into a semi heavy barrel for 7.62x39 or 54r..... Barrel Parts - Omega Weapons Systems (520) 889-8895

1biggun, here is a picture of a d-max rifle. I know its different than what you're doing, but I thought the picture might be of some use. It uses a pps43 looking bolt that uses a sten type extractor and a regular ak style FCG. One of the hammer sear surfaces has been removed to clear the guide rod. Since you're making a new style bolt (not a previous FA bolt converted to semi) you can have feed lip on it and use a plunger type ejector like on the M1 garand, M1 carbine, M14, M16/ar15 ect. I'm thinking about going with a plunger type ejector on a 17hmr build I'm gathering parts for. I had a like new remington 1903a3 (that I'm still kicking myself for selling) with a two groove barrel and it shot very well.
Either way, looks like you'll have a nice cast bullet shooter. Probably won't lead any worse than a rifle, just use straight wheel weights [or other hard lead] and it'll be fine.
