H. K. Uriah, SASS #74619 Posted February 9 Posted February 9 I have a need for some customized brass. Basically, I want some .45-70 trimmed to .45 Colt length with no other modifications. Don't care about the headstamp. I've contacted a few folks I've found online whose websites indicate that they MIGHT do it, so I asked. So far, no responses. Except for Starline who said they can't do it right now. Maybe in the fall. Minimum order of 100,000 pieces. I don't need THAT much... I am looking for 500 to 1000 cases. I know that in some ways, that's not a lot, but it is just trimming an existing case that is easy to get. Yes, I can do it myself, but it's a tedious process. Anyone have any suggestions? Quote
Boggus Deal #64218 Posted February 9 Posted February 9 Have you looked at .475 Linebaugh brass? John trimmed down .45-70 to make that cartridge. Quote
Idaho Gunslinger Posted February 9 Posted February 9 Can I ask what these are for? You could always get one of those electric case trimmers and do it yourself. Likely the most time consuming option but probably the cheapest. I wonder if this could be done with a Dillon press mounted case trimmer. Quote
Boggus Deal #64218 Posted February 9 Posted February 9 Looking at it, the .480 is already the exact length you need. 1.285”. The case body is the correct size but the rim is slightly smaller diameter. Quote

H. K. Uriah, SASS #74619 Posted February 9 Author Posted February 9 Ah! I had not considered the possibility that some other existing case might actually be what I am looking for. I shall do the research! Here's what I am doing. I was trying to "develop" a sub load for use in my single shot .45-70 rifles. Started out by trimming cases to ,45 Colt length, and loading them to .45 Colt pressures with a 300 grain bullet. Works pretty good. On a whim, I tried running them in my repeating rifles, and to my surprise, they worked! They worked well enough in a vintage 86 Winchester, and quite flawlessly in a large frame Lightning. I even had Lee make me some custom dies. So, this is a kind of "project" for me. It's 100% for fun and has no practical application, but it is something I am enjoying. I have even toyed with the idea of trying to figure a way to get a revolver in caliber, (I was calling it .45-45) something other than those behemoths chambered for .45-70. Yeah, I could obviously use the round in those, but the mind is a funny thing. Thanks for all the suggestions. New possibilities are opening up. Quote
Boggus Deal #64218 Posted February 9 Posted February 9 The .480, other than the rim diameter, I think would do fine. You may have extraction issues. 1 Quote

You may have extraction issues. That's what I was thinking. The .480 would give extraction problems. The .475 would work, and while it would not have to be trimmed as much as the .45-70, it's a lot more expensive for the brass. Still, it is something to consider. Quote
Flat Top Okie Posted February 9 Posted February 9 How does this compare to a .450 Bushmaster? FTO Quote
Cholla Posted February 9 Posted February 9 RCC Brass used to be the company to make custom brass but they went bankrupt in 2022, right after declaring they had a way to get an extra 100-300 fps out of standard cartridges using their revolutionary brass design. I drove ten hours round trip to talk to the owner for a story (after he said he would give me the information) only to have his partner say they didn't want me to do a story on it. Two days of my life and an expensive hotel room were wasted. But I'm not bitter. 1 Quote

Duffield, SASS #23454 Posted February 9 Posted February 9 Have you tried a tubing cutter to shorten the 45-70 brass? Cut it a rch long and finish with the trimmer. Quote
J.D. Daily Posted February 9 Posted February 9 Use a cheap Harbor Freight mini chop saw like used to make 300BO brass out of 556/223 brass. Cut to slightly longer than 45 Colt. Then trim to finish length. 3 Quote
Stump Water Posted February 9 Posted February 9 How are you dealing with the case wall thickness that far down vs. at the usual case mouth? Or are you taper crimping? Quote
Abilene, SASS # 27489 Posted February 9 Posted February 9 FYI: https://www.rockymountaincartridge.com/products.htm quote from that page: We do not supply any load data. Still not cheap, but minimum 1 box, not 100K pieces. Quote

Several threads where he is making custom jigs. You might get lucky. Cut to within a few thousandths of OAL. Finish in power case trimmer. Quote
Earl Brasse, SASS #3562 Posted February 10 Posted February 10 Sedalia Dave has the right idea. I just bought several jigs to cut down brass to do case forming of various calibers. This guy on E-Bay will make custom jigs. https://www.ebay.com/sch/empoweredlearning/m.html?item=304125853547&rt=nc&_trksid=p4429486.m3561.l161211 Item I bought was https://www.ebay.com/itm/304125853547 Good luck with your project. 1 Quote
