577 450 MH: Newbie needs help

[roys101]

Hi. I have a Mk IV, 1887 long lever rifle. I need brass and a mold. Can anyone recommend a mold? Dia. needed might be .470 (?). Best deals on brass? Thanks. Chris.

Roy, You are in luck! There is a group buy of 'Tini molds at
http://pub182.ezboard.com/bbritishmilitariaforums
in the vendor section. Read the ad and sign up. Those guys will help that old hoss bellow again.

Jim makes them specifically for MH. Just cut a new design at Xmas.

Roy,
I think that the mold buy has closed but they have a group buy on Jamison brass at as good a price as you will find anywhere. You will need to sign up to get on the board but it's a good group of guys and there is a pile of imfo that you can get from the board on the MHs.
You might try one of the Lee 475 molds for a pistol, should be about the right size and reasonable cheap.

The mould order page is still up on British Militaria forum, so Michael is still taking the orders but I'd get in quick.

I can second the option on a CBE mold. Jim can also do up a PP mold if you wish to go that direction.

Bruce Bertram can supply brass if you need a source.

My local baitshop lists Bertram 577/450 for US$109.75 and Jamison for US$59.98, both for 20 cases.
Jamison is the successor to MAST, who succeeded Bell. The brass appears the same as Bell at first glance.
Cheers from Darkest California,

There is group buy on brass on the British board as well. Check out the link above. Looks to be about $2.15 ea plus shipping. The brass is Jamison under the TenX head stamp.

Gulp! I thought .45-110 brass was high priced!

Charlie, do they have it in stock? I know several folks that have had it back ordered for some time.

Couldn't say...I only saw that it is listed.
If I showed a deeper interest...they might want me to BUY SOME!

This Jim Allison's new boolit. One advantage is that he will make you a top punch at the same time. One disadvantage is that his production is backed up till May.

It can be had in 480 gns and 58o gns from memory and it apparently is a pretty close copy of the boolit they used to use.

Probably easier for you to source on in the states, but Jim does make fineee moulds.

What's the diameter on the new CBE Mould for the Martini?

Douglas,

Please stop drooling!

I can't personally guarantee that it works, but a knowledgeable friend tells me that MidwayUSA sells 24 ga. brass shotshells that will form nicely into .577-450 cases and they're MUCH cheaper. He said there's no need for case rim modifications and claims that he's used them in his Martini with success. You might want to investigate this option before you buy. There must be SOMEONE on this board who can confirm or debunk this...
Good luck with your Martini!

One of our regular Africans is the guru.
Douglas is da man.

I think that the 24 gauge brass is for the .577 Snider.

Ross is right about Douglas, but he probably won't get to this till tomorrow.
These are my observations. I have about 75 of the converted 24 guage brass and they do work, but they are shotgun shells so there is no thickening of the brass towards the base like normal rifle brass. It takes several different sets of dies to form it and you have to anneal between each pass. After several firings the base starts to dome because it is thin and then the rounds won't chamber. The 24 guage brass also takes about 115 grains of BP to fill it up and the LOC load is 85 grains. By the time you go through the process to make the brass you can have proper brass that will last, for $2.05 each. When there wasn't an option this was the way to go but now you do have that option. Get the right brass, you won't be sorry. Been there done that!

Got to agree that the right brass makes life a lot easier. The 24 gauge brass is a good option when there is nothing else or thirty bob a case is OTT. To be honest it makes better .577 Snider brass that 450/577, 450/577 being to all intents and purposes a necked down Snider. The large case capacity is an BP issue for a bottle neck, it can be reduced with a combustible liner but its another step and only for those weirdos with an arcane bent like me.

I've just recently started using Jamieson brass, from Buffalo Arms the exchange rate is good for us Brits just now, and rate it. Prior to that I was using Kynoch, as expensive as Bertram but much better.

I don't rate Bertram brass at all having used it in a few calibres now and found it variable at best. The necks split after a few firings and it doesn't seem to anneal well.

Go with the Jamiesons I say, the British Militaria forum are doing a group by on brass, I'll be in for 100 each of Snider and Martini when it goes live, don't know if it works out cheaper but I do like to support self help.

[dromia]

BTW I do like the look of the new CBE bullet, he makes great moulds.

Is it on his web site yet or do you just email him.

I'd like to know the diameter it drops at too.
