.577/450, Where to buy reloading components?

[rocklin]

As the title says, where can one buy reloading components for .577/450 M-H?.

Formed brass or 24 gauge brass shotshells and a source for cast bullets are what I am looking for. I don't currently cast at the moment(looking into it).

any information would help.

Rusty woods usually has 24ga and formed brass. To bad your not in N.S. I have 3 different moulds. Shipping for lead not good.

Martyn also sells the correct size bullet mould. Even though the Martini is nominally 450 the bore starts out at .469" and tapers down to .465" so a .470" diameter bullet is the way to go.

I slugged the bore and came out 0.459. With this old stuff bores can vary. I found 480 gr or 500gr worked best with 80 gr black powder. 30 thousand card and SPG lube.

I use a paper patch to bring the dia. to .480'ish. I use 15gr of 700X

Snider Shooter, is your Martini a Nepalese made Gahendra? Those do have a bore of .457 to .459 but if you have a British made Martini turn the lead you used to slug the bore with as you mike it. The Henry rifling is not so easy to get a reading on.

I would have to get them out to have a look,but I believe one is a nap. I know Lyman 457125 works good. Last time out I was hitting a 3/8th piece of chain at 50 meters and under 4 inches at 100 meters. 80 grs 2f Goex 30 th card , SPG for lube. This was standing not benched. We aimed low at the 50 and was hitting 8 in high at 100 m. Old hand at bore slugging. If I have to make cases even better. Bullet is half w-w and flashing , same as I us for all my BPC guns.

If it works that's all that matters.
