What is this mould?

[The Double D]

I picked this mould up this weekend at a shoot here in South Africa

It is a nose pour ejecting adjustable base mould.

The mould is marked .462 which coincides withthe bullet diameter.

It is also marked 53 on each block

The base is dome shaped and looks like the dome on the base of a bullet intended for paper patching. The sample bullet weighed in excess of 500 gr.

The mould needs some cleaning up but it looks like it is in pretty good shape.

Is anyone familiar with this type of mould or have any idea who made it?

..................I'm familiar with that 'Type' of mould, and in fact there is another similar to that. It's an adjustable wieght mould where you can move the base plug up the cavity (meant to stop at each drive band, which becomes the baseband), thereby creating a lighter slug.

It appears as if your mould is also slightly adjustable, but not by very much. I don't know who made it although the block design does look like a Lyman. The nose design in the cavity does not look like an older Lyman though.

That diameter (and your location) says 577-450 Martini to me and specificly the Mk1, II, and III. A bit small for the MkIV which wants a .468 to .470" GG slug. Then again, even with those GG's it very well could be for paper patching. At that .462" diameter, 9# onionskin would put you right close to .470".

WHAT a find! It was made with much forsight - note the texturing on the bullet for Lee Liquid Alox!

Lyman advertised this style of mould for years as the adjustable. The last ones were made in the fifties if I remember right, Floodgate will have all the data on this. The adjusting screw on yours has been shotened as on the one i have the screw is long enough to cast a bullet from about 190 to 490 grains. They are an interesting idea for the one gun man, but on mine I only cast one bullet from it so the adjustable feature is wasted on me. I have the photos and numbers for these moulds in an old (1894) Ideal catalog and i will try and did them out and post them this weekend.

DD:, KCSO:

Though the blocks look Ideal-ish, the sprueplate does not and the rounded corners don't look "right", either. Though the approach is similar, the old adjustable Ideal "Perfection" moulds were made only in the pre-Lyman style where the blocks were integral with the handles; these were discontinued after Handbook No. 17 in 1906. (I have seen a photo of a pair of Lyman-era hollow-base mould blocks sorta like this, but not identical - possibly a special order.)

The bullet weighed 558.7 grs.

The base screw that is with the mould does not look cut down as it appears machined and Machine slotted. That doesn't mean there couldn't have been another base screw set up. The adjustable base that is in the mould will not fit in the grease grooves...darn!

The grease grooves have an angle to them. I could make a new base plug, but my lathe is 9000 miles away.

I will clean it up and make bullets with it next week and try it out.

Buckshot, of course it's for the Martini. I can't think of anything else worth shooting. :)

Douglas,I know this is an old post but maybe you still on here .I have exactly the same mold with no name or numbers except the numbers "61" on both split pieces.Slug out .458 , 540gr and shoot this in my Martini Henry with great accuracy.
