    i want to get a 45-70 single shot rifle, the h&r buffalo classic to be specific. i already reload for other calibers but for the 45-70 i want to cast my own bullets. im wondering if someone could explain the process of casting your own. i dont quite understand if you have to gas check them? ive read that you gas check them if you want accuracy but please correct me if im wrong. and if you gents could recommend good equipment for gas checks. thanks alot

    No you do not need gas checks on the 45/70 bullets. Gas checks are used for "hot" loads.

    Yes you must lube cast bullets. You may tumble lube in Alox or run them thru a little Lee sizer. In most 45-70 caliber rifles .457 you will use a cast .458 bullet. There are more expensive lube and sizers by Lyman, RCBS, Star running in to the hundreds of dollars.
    The LEE sizer and a bottle of Alox will be under $30 bucks. The LEE mold blocks will work just fine at a bargain price. Gas Checks are used at 1,500 fps pressures in barrels over 18 inches. Good Luck.:)

    Find the Lyman Cast Bulllet Handbook (if it is still available). Detailed info on casting. Think of all the knowledge you have about reloading, you will need to acquire at least that much moe about casting to get started.

    Things to learn;

    Temperature ( of the alloy and the molds)
    Alloys and how to make them
    Fluxing
    Skimming
    Lead as a hazardous material
    Mold preparation
    Proper sizing
    Reading the bullet (frosted,wrinkled, shiny, dull, etc)
    Heat treating
    Gas checks, yes or no
    Lube - types, anounts, proper choices for expected velocities/powders
    Seating
    Cleaning the gun after.

    And this is without getting into things like paper patching, bullet indexing, hollow pointing, differential casting, etc.

    I could go on for days, but I took the time to buy the books and read them before I got started nearly 30 years ago. There are no shortcuts (sorry Gen-Xers).

    the speed your bullet is traveling kinda determines the hardness of the bullet you need. the hard part is setting up a safe area to flux the lead melt getting the right alloy mix and finding a source of decent lead. none of it is that daunting. im just getting started in rolling my own as well.

    currently constructing a fume hood for my smelting pot to be vented to the outside so i can cast bullets in my basement.

    +1 on the Lyman cast bullet handbook.

    I use a Lyman single cavity (385 gr) mold and a Lyman lubrisizer with Thompson's "Blue Angel" lube. I prefer to use gas checks. I cast from straight wheelweights.

    That's not the only, or necessarily the best way, it's what works for me.

    There is no way to describe the satisfaction I felt when I first bit into a venison steak from a big Mulie buck that I killed with my Marlin 1895 .45-70, shooting a hand load with a home cast bullet.:):)

    What kind of velocities are you getting with the 385gr..?

    Cast bullet alloys are chosen by the pressures developed by a particular load.:)

    I haven't started reloads in the 45/70,s yet , but do want to. I'm not caring for the "Lesser loads" because of the lobbing or rain-bow trajectory . Plays hell on my scope settings . I'm not totally new to reloads , but am new to the 45/70,s.

    Tell me more about the "Hot-loads" and what is necessary..! Or , sources of data , books , links , etc...!
    Would the (Lyman's cast bullet hand-book) be one of the sources.?


    Thank you..!

    Well , according to the Hodgdon data center , just about all the loads are well over the 1500 vel...? So gas check would be an absolute..?

    im trying to find some loads for the 45-70 but in my book it only has it for the trapdoor, marlin GG, and ruger #1's. do you guys know where i could find data to use in the buffalo classic h&r?

    The use of gas checks really depends on slugging the barrel, so to know what exact bullet resizer you need. You can find out how to slug a barrel by going on YouTube and searching. Once after that I would make one cast bullet reload and fire it through you rifle. Then check your barrel for leading. If no leading then no gas check is need. If just a little bit of leading at the last say inch of the barrel then you need to use a gas check. If a lot of leading accrued then it could be a few problems, ie cast bullet hardness is too soft, you slugged the barrel wrong so the resized cast bullet is wrong, or your you are just using a over pressured round which you just need to check the base of the brass for a crater effect of the primer, primer maybe coming out of the primer pocket, or any blackening of the base of the cartridge, so all you have to do is back off on your powder load or check to make sure you collective overall length is correct. I do have to say casting you own bullets really is a work of art an death hahaha.

    In my opinion the H&R 45-70 rifle should use the "Trapdoor" loads only. The loads listed for the Ruger, Mdl. 86 are very high pressure. The H&R standing breech system is far too weak for those loads. :)

    looks like a bit of equipment to start making your own bullets. im going to see if i can find the lyman casting book this weekend at the gun show!
