38-50 Cases (Read 4467 times)

	Am wondering if anyone here has made 38-50 Rem cases from 30-40 Gov't brass? If so, how did you do it? Am thinking that annealing the necks and running through the 38-50 FL sizing die is the quickest & easiest, but am wondering if annealing and then fire-forming with 10gr of Unique & C-o-W is better? Essentially one 'bang' and the brass is ready to load. Thanks.

	I bought a tapered expander button and opened up the necks first. I annealed next and then full length sized; cut to length and they are ready to go. If you use this method, don't anneal first as you will have some cases collapse.

	I first run 30-40 cases thru a 38-50 full length resizing die. Then I load 13 grains of bullseye in the case and then fill the case up with corn meal and put a wax plug in the case mouth. I have never lost a case and I do not anneal first. I want to add that I have formed about 500 cases this way and I do not recall ever loosing one. However I have had a few that did not form completely with just one firing.

	Agree with the above. Expand before annealing. Had some trouble with the base of the case. 30-40 case is nearly straight at the base. 38-50 reamer is tapered near the base. Sizing down the base presented some difficulties. Cartridges would load tightly but tough extraction. Chuck

	If you run through the FL 38-50 sizing die then why bother with shooting with a fire-forming load? Why not just anneal and a 'normal' load with the lead bullet and shoot? BTW - someone was saying that they couldn't find 30-40 Gov't brass. I just bought 100 new R-P from BACo at $0.64/case, plus shipping. Assume they have more.

	If I am not going to size the necks, but just load into fired cases, then I don't anneal. In my experience, it does fine to make an expander button with steps on it, about 0.030"/step, lube the necks and shove in the expander. This expands, e.g., 30-40 to 40-60 in one pass with no loss. I have tried expanding necks with quick powder and cornmeal and other fillers, and end up with asymmetrical necks and other problems. The straight guide sections between taper steps seems to keep everything well-centered. With the resulting hard necks, I don't have any stretching on firing. CHRIS RGChristensen

Why not just anneal and a 'normal' load with the lead bullet and shoot? In my case a 30-40 case would not fit in my chamber unless it was resized in a 38-50 FL die first. I do not have an expanding die and fire-forming with corn meal and bullseye forms perfect cases. Back when I was forming cases I often brought several cases to be formed and shot them after shooting BP loads. This worked nicely to burn out the fouling and made cleaning the bore a snap. In my rifle after fire-forming the case is longer than the chamber allowing me to trim them to a perfect length for my rifle.

	This works for me; 30-40 Krag case, 10gr Bullseye, fill case with cornmeal, dab of lube to hold everything in case, fireform, trim to length to suit my chamber. I also ream the inside of my brass with a .375 reamer to make them consistent.

	Steve Rhoades of Arizona Sharpshooters makes an expander ball designed for just this purpose. He is making up several in the next few weeks (he is also running the AZ State BPCR matches (You need to *Login* or *Register* to view media files and links), so is pretty busy). If interested you might want to let him know you would like in on the order.
