    Grendel and PPC brass would work since it uses the same base as 7.62x39. Other similar-sized brass should be able to resize to fit. I've collected over 1k of x39 brass so I'm all set

    I'm not going to ream my own dies - I don't believe my mini-lathe is up to the task and I really don't want to risk damaging the reamer or the dies. My luck I'd end up reaming the die out of round and wonder why all my case necks aren't concentric.


    I'll make some calls later this week to get some quotes.

    Spent cartridge off to Pacific! "Please allow 1-4 weeks for processing"

    He recommended Hornady dies. I need to call them to find out how much but according to their 2010 catalog their prices are competitive with other custom die makers.

    I thought the needed a sized dummy round not a spent round to make a die from?

    one would thing you would want a way to amke the ammo before the reamer for the chamber.

    Lee asks for a fired case too. I'd assume they tighten up the dimensions a specified amount, and the neck to whatever the bullet ends up being.

    I could see using a fired case because then you have a die tailored to the firearm the brass was fired in, so Pookie'll have a die to reload for a rifle in russia, but then he can get the chamber reamer cut to the same dimension as the fired case he has, so then his chamber will be right for the die. Factory ammo might be a bit loose, but it ain't available so that's a non-issue.

    With my luck there would be around 9,000,000,000,000 rounds of factory ammo imported the day after I finished my custom 9mm wildcat. LOL

    He said typically for gas guns the chamber specs are .001" larger all around. Gauging off of the AK chamber casting I have I'd say it is even more loose. That could be one reason for poor grouping in general as they made a fundamental trade-off of a looser chamber spec for reliability. Due to the nature of this round I would say that .001" would be fine. He did say that steel springs back differently than brass which is something I didn't consider.

    I was exchanging emails with someone few years ago who checked into it and you could import it from the factory but there was a minimum order of like 1 million rounds, which isn't really financially equitable since there aren't any chambered rifles.

    Either way I'm confident that it will chamber factory ammo if ever it arrives.


    I'm not sure how to go about reaming the throat. I guess I will need to pick the right bullet and go with it. The Nosler 250 grain 9.3mm are on the top of the list because they have that ballistic tip which will help feeding. There are some Barnes bullets too that look good. I think Hornady has 9.3 ballistic tips now too. We'll see what Dave says.

    some x39 chambers are really loose especialy in three neck. fine tuning ammo to fit the chamber better really helps accuracy thats why i run as little head space as i can.

    I think the .001 is extra over what a normal gun has already. Im betting there will be some were around .007 total.

    Id have the reamer made with the neck and throat incorperated as long as you know the bullet dia. another throating reamer will add another $45-$50 to the cost of things. However it would be nice to have to allow you lengthen out the throat if you need to for longer bullets.

    there are so many considerations and things to think about when doing a wildcat.
