Just My Name Thank you for the kind words, glad you found it useful 😀

Thanks very much, really appreciated 😀

Thanks for the. Kind words!

He was being sarcastic

Thanks very much

You are welcome!

Thank you, I appreciate the comment 🙂

Thanks very much for the comment. They are fantastic to shoot, one of my favourites, just love them, enjoy!

medhist2006 Thanks for the comment, it's appreciated 😀

William Haley thanks very much for tour kind comment 😀

Mark Robinson you’re welcome. Looks like a lot of fun. Might consider one of these one day.

Gunmonkey5 Think, you put this comment on the wrong video, and I know which video it should have been on😀

Peter Petrakis thanks for the kind words! 😀

britishmuzzleloaders Hi there, thanks for the kind comment. Regarding the spacer, It is difficult to explain, but I have used a bit of 22mm copper pipe and a 22-15mm fitting which I have cut the top off. In response to your question I have made a short RU-vid VDO to demonstrate, which I am just editing and will be live later today, so I will post a link for you - hope it helps.

Hope this helps! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-j9B4EucFe6o.html

Peter Martini Hi Peter, thanks for the kind comments, with the brass i just use corn cob media, actually lizard bedding, and a bit of car polish, but it does take a few hrs. Only ever annealed once, so i would say very infrequently. Good shooting!

As long as you're using fire-formed cases in the same rifle neck sizing is all that's required. In addition, the Lee 577/450 dies are well over $300 whereas the 480 Ruger dies can be had for around $40. One more thing to bear in mind is that the Lee 577/450 dies have a 1.25" thread diameter which won't fit into an ordinary press which will only fit 7/8' diameter dies like the 480 Ruger..

Glad you found the video helpful. How many reloads will depend on how much you resize them. If you do just the minimum to the neck then you could get 20-40 or more.

Mark Fung Think I probably have best results with 85 grains, but i have experimented a lot from 75 up to 100 and it also depends on the powder quality. Good luck with your loads 😀

the 357 casing was a really smart idea

Rock Stomper sorry, not really able to advise you with that, hope you get it sorted though! 😀

Hi there, I use a 456-480PP Double Cavity brass bullet mould I bought a few years ago from Cast Bullet Engineering, not sure if they still do it. I do not resize the bullets, just paper patch them as they come out of the mould. I cast in pure lead, hope that helps

@@MarkRobinson555 Sorryi should rephrased that. i just was doing research and couldnt find much definitive info. some ppl were using 457 some 468 some are even using 475! I decided to get 457 and PP cuz the mold and sizer are cheap and available. I didnt see anything besides that. but in the future i would like to get 468 or 475 grooved bullets so i dont have to PP. Im using pyrodex so fortunately i dont need to make grease cookies. I learned a lot in the last day.

Jake Wesley Hi, I only use the spacer to prevent possible damage the the shoulder, if you are careful you don't need it.

Hi there, I use a mixture of Bertram and Jamison 577 NitroExp, which has been reformed.

Probably a bit late, but you can reduce the powder charge to a certain point (as low as 60 grains) but if you reduce too much, it may be dangerous for the rifle

No, dont size or lube

Yes they were 😀

Ork Eng that depends a-lot on the quality of the brass and how much you resize, but you could expect 20-50 reloads or even more if you anneal the brass, to reduce the work hardening from the constant resizing

Mark Robinson thanks for that.

Midway USA had it last week

Its a shotgun cartridge case, can't remember the exact size and I don't have it with me, but it was not the standard size.

Hi there, I would resize the neck of the cartridge and then flair the mouth. I would only resize the whole cartridge when it is tight in the chamber. Hope that helps

Yes , thank you 😊

Thanks for the comment and support, its appreciated. Its a long lever and I shoot in the UK. No such thing as a typical day! hahaha, but probably 10-20 rounds

Mark Robinson thanks, being a Heavy Caliber and Single Shot I didn’t know how much was much in terms of Ammunition. Expenses aside (obviously yours is very expensive!) your Shoulder dictates how much I’m sure! Enjoy!

No crimp, think that would probably destroy the patch. Just straight neck sizing

Thanks Mark

Thanks for the kind comments about the VDO, and you raise a good point about the static, perhaps I should change - safety should always be paramount - thanks.

Should not be a concern. See here for issues and tests related to setting off powder with electricity. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Nm6PEdBcQ6s.html

Sam Chapman thanks for the kind words. I would say that the wax and the paper discs are important. The wax provides lubrication and the discs separate it from the wading and powder. I have not tried to exclude them, as I have just followed the original load procedures for this round. Regarding the wadding, I and I know others have used foam. You can get lengths of circular foam, cant remember what it is called, but it can be cut to the appropriate length and it worked quite well. I and others have also used semolina powder to take up the air space, with good success, but I know that there are are those who would criticise this saying it leads to a build up of pressure, so I would not recommend it to anyone. Newspaper, not sure, as long as it took up the airspace and didn’t cause a blockage I don’t see why not, but not really sure, so I can’t really advise you. There are a couple of Martin Facebook groups and a Paper patched bullet group you could join, sure you would get plenty of advice! Good safe shooting!

Mark Robinson Hi Mark, thanks so much for that very informative reply, I'm very grateful. I think foam or cotton wool sounds like the best option. The Facebook page sounds like a great idea! I'll join up to it now, are you on fb?

Mark Robinson Thanks Mark, I've joined the Martini pages as well. Thanks so much for your advice and insight, much appreciated.

Don't know whether you have seen my other videos, but there are several that cover Martini reloading, may be worth a watch :)

Hi there, there is a lot of recoil, but as it is black powder it is not such a hard hit as modern powders, I would say it is more of a heavy push! Check out one of my other clips, on my channel where i am shooting it!

No crimp, just I tight fit in the neck

Andreas191280 just normal A4 80g copy paper 😀

Hi, sorry for the slow response, I use an #22

Brian Meyette possibly more expensive than it's worth.

303 is a great round, but you cant beat the thrill of shouting on of these big rounds!

@@MarkRobinson555 for sure. My local gunrange is indoors though so they dont allow black powder anyways and I have no tools to reload at home.

Del Allen Preparation is a really important part of reloading, not just wrapping and seating the bullet, thats why I show the whole process.
