@Marty Henry good man

The bigger the data set the better the result
Expect to see barrel maker this week and nudge along the 577 barrels
Have a nice restoration to take along for him to shoot
So that might inspire him

I re formed 24 gauge magtech brass to 577 Snider yesterday

Will take it to Vulcan barrels tomorrow as inspiration to start on my two new 577 1:25 twist barrels

Magtech formed nicely into 577 Snider
Process is
Cut to 51mm
Anneal
Form in full length die with plenty of lube
Clean
Re anneal
Re cut to final length. Brass was 0.75mm longer from being formed

Have two more boxes of 25 to form to snider so need to find an easier way to cut to length than using the lathe

mini drop saw? Hobby shops may have one

Yes they seem to be what get used

Just need to see who has what and if anything is in stock

Whap a hole through a block of steel at the right length, hacksaw off then clean up with a file? Sounds brutal but works and quicker than machining.

As it's supposed to be a super snider you should have left the brass full length surely (-:

There is more than enough space in a standard snider case

But if it goes well I might make a 577 2 1/2" light nitro

In a strong action ( Baikal 12 gauge single ) the 577 Snider case would be plenty as a light nitro and you could go up to a 750 grain bullet

Just don't use your Magtech cases consistantly for Nitro loads. They dont have much of a web and start thinning out very rapidly in my experiance.

Its popular amongst the old blokes to fire a couple of nitro rounds through their BP cartridge rifles at the end of a shooting session to help clean the bore. Strange but there you go.

Personally the magtech are for BP only
They formed perfectly to the snider cases

But I can see they would not be nearly as easy to form into 577-450 MH

If I try nitro it would be with Bertram brass
