I know there are tomes , 45-70 .

But here goes .
I bought a 535 mould and it's just too long to load as a grease groove bullet for the Marlin . I'm sure it will be fine in Jorge's 73' Springfield .
It would be passable as an Indy 45-60 1.8" straight case thingy . I liken that to 38s in a 357 , in the crud ring context .
This leads me to the paper patch and deep seat on a compression resistant powder charge . I do have a 460 S&W FCD that would hit the top lube groove (see the 1.8" Indy thing) .
In my twisted mind this seems like it should work like the 7.62 Nagant with the case crimped over the bullet sort of . I've prepped 37 pieces of Hornady LevEvolution brass so if it is a spectacular failure at least it won't ruin good brass . I will of course see "the dreaded rings" . I expect this to be either into to the low 1300s or under 1100 fps MV and to , after a pass fail test , form a cup point anvil for the Lee sizer and size base first . It only needs .006 to get to fit by math with my pistol alloy .

Any suggestions other than the obvious of get a mould with a proper nose length ? I have a 460-420 MP and 458193 but I wanted something slicker and as an option for another project .
4831 and 4350 are on deck for the to slow to get hurt value . Although they may well be coming into the bottom of their curve at this point .

The obvious solution to me is to hollow point the mould and use a blank spud, large diameter, that will truncate the nose in the proper place. There may not be enough meat on the bottom to do a regular HP pin, but one with a large shoulder on it might work. Another option would be to machine a flat-point nose insert and pin or screw it to one block half.

The objective is really to use the high BC to it's best advantage . If this were a 500 gr Lee the change of the nose wouldn't be a big deal in the mould but it's an NOE version of a Money like copy . The 459-543 RN . A poorly planned purchase for this rifle better for the alternates.

Use something like 3031 or RX-7, or even XMP5744 and Cream-o-Wheat. Tappy-tap-tap to settle the powder, ladle in your COW, and seat to compress, then lightly crimp over the front band. 4350 and especially 4831 get stuuuuuupid in a straight case without a kicker charge of a quick rifle powder. Rumor has it also need to watch out for blowing your muzzle off using slow powders in a case with a prime expansion ratio.

Well now that I have that information .......... Lady luck will no doubt walk away ....

So much using the cartridge as intended and making the rifle work for it . Maybe I'll find a nice 45-90 action hooked to a 45-70 barrel . Probably not . Time to mill a Lee 500 , to make it a PB nose pour .
