    Thanks for the link. It doesn't want to let me look all the way down, so will keep trying. Emery

    First, two questions:

    (1) What caliber is your RB?

    (2) Have you actually slugged the bore to measure its true groove diameter? If your bore is at all oversize, it may be easier to get a .375 mould, cast a 25-1 or 30-1 alloy, and size your bullets down to .001 or .002 over your actual groove diameter.


    So far as finding a .366 dia. mould, I did a quick browse around for ANY mould of that size in production by ANY manufacturer and came up empty. Unless you can find a "vintage" Lyman somewhere...and the #366408 was the ONLY .366 dia. mould Lyman EVER catalogued...I'd say if you really need a .366 bullet dia. you're stuck with two choices: (1) Have a mould custom made or (2) Find an RCBS 35-250-SP or a SAECO #353 (both drop .358 dia. bullets of approx. 250 gr.) and open the cast dia. to .366 by some (very) careful lapping of the mould cavities.

    Of course, there's always the option of having can your Remington rebored/rechambered to, say, .38-55 or .40-65.

    BTW..

    After I posting my earlier comments, I got to thinking about it and realized that I had probably, at one time, put a bid or two on the RB that you've got. Went over to GunBroker.com and, sure 'nuff, I had bid on that same piece at one time.

    Congratulations on getting it. Sure looked like a really nice RB but, when I was bidding, the seller had his reserve considerably higher and just wasn't willing to up my bid without more information than the seller could provide at the time.

    That is a very sought after mold and most times brings premium pricing at auction sites. It is also a Loverin design which generally are used in long necked cases with better results but I don't know the cartridge your loading for. There are a number of custom bullet makers who will cut anything you want, if you go that route size it to the throat diameter if possible. A custom mold runs 130 or so. Also check out NEI, they have a lot of stantard molds for most any caliber.

    Thanks for the responses guys.....I did some further checking, slugged bore (~.372)and did a chamber cast. Now I am looking for a sizing die to use on some 375 bullets. I have contacted a fellow on another forum that does custom stuff like that. Looks like the brass will be 38-55 with rim turned down a bit. Maybe Teak will add his knowledge to this mystery cartridge!!?? I'm still not sure what I have, but I WILL get it to work. I loaded a 375 bullet in a case and ran the loaded round in the FL Sizing die so it would chamber (neck had expanded too much), and fired the rifle. I would like to not have to do that extra step, tho. Yes, it is a nice looking, unusual rifle. Emery

    Shooter93, yes NEI does have a few molds in 336 diam. I contacted a local bullet casting operation and they have 225 and 250 gr GC NEI offerings. Emery

    If it's a straight-wall case and a .38-55 will chamber , it's probably a 9.3x48R. (See Barnes "Cartridges of the World" - ppgs. 257 and 265 in my older edition) Midway USA catalogs Bertram 9.3x82R brass which can be cut to form any of the (5) shorter versions of this family of cartridges.

    Bill, I can't seem to find that cartridge; I have the 7th and 10th Editions of COTW. The 7th has a 9.1 by 47 cartridge which would be the correct bullet size (.372) but the case is too short. Can you give me the base, rim, bullet, and brass length of the 9.3X48R? I could neck down if all the other dimensions are close to 38-55. I am thinking that I may have some sort of European wildcat here, say something like .372X38-55. Emery

    Hokay...

    Here we go on the specs on the 9.3x57R from Barnes (3rd Edition)

    Case type: Rimmed straight
    Nominal bullet dia: .365"
    Neck O.D.: .382"
    Base dia: .433"
    Rim dia: .492"
    Case length: 1.89"
    O.A.L.: 2.35"

    There was also a 9.3x57R from the same family of straightwall cartridges with the same dimensions except for case length and O.A.L which Barnes lists as 2.24" and 2.80", respectively. This is NOT the bottlenecked, rimless 9.3x57 Mauser round which is still cataloged by DWM and Norma.

    Hope this helps some.
