Re: 25 Stevens Ammo Dimensions
Making a breech block tells me your a pretty handy guy. I would suggest that you consider using 22 Hornet cases and run those cases through a custom die by RCBS that will open the case mouth to accept .257 bullets and then re-chambering your rifle instead of making center fire cases. I just looked up the dimensions of the Hornet and it would work well. As for bullets your original weight was 67 grains when re-chambered it I would make the chamber accept .257 bullets so you could just go buy them anywhere, but then you would ONLY be able to shoot "progressive burning" smokeless powder and never never black powder. The added .006 on the diameter won't hurt a thing with smokeless powder. See P.O. Ackley's Handbook for Shooters and Reloaders Volume II. He has a piece in there titled "A few cases of blow ups" and that should put your mind at ease utilizing the larger bullet. Also some manufacturers at the end of production were loading the 25 Stevens with smokless powder. I hope that helps.
