Jamison .45/110 brass

[Don McDowell]

Wondering what would happen if you used greasers and your special blend of powder to fire form those cases.?

Don, Good idea, and it's one I already intend to work on the next time I'm working w/ the Jamison brass. I've got a good cache of Lyman rd. nose bullets on hand (#457125) at present, and already planned on doing that next. I've done that before in the past w/ these bullets to lengthen the cases up to full length. Works good, and those rd. nose bullets shoot really well to boot.

Another thing I tried today just for grins is full length sizing several Jamison cases in the Lyman full length sizing die, and then resized those cases again w/ the RCBS .45/70 neck sizing die until they bottomed out. That was good for a total of 0.003-0.004" increase in case length. I suspect a full length RCBS sizing die or a custom sizing die would do the same thing and maybe better, but the RCBS dies for the big calibers were rather pricey when I got into this game.

It will take a little more tinkering and more shooting, but I'll get those cases jerked to full length one way or another. However, that's not the best business recommendation for Jamison brass either, at least in this caliber.

More than a little disappointing to have a .010" shortfall in new cases. I would imagine they manufacture to a tolerance that allows for 'those' that dont measure their brass and arent interested in trimming cases back but that seems quite a shortfall when most of us are looking for cases that are 'right on the money' for length ..or a tad longer. Different case I know but my 44/77 Captech arrived right at 2.25" ..so I couldnt fault that...but they shortened over .010" on fireforming in the rifles chamber. Given the myriad of 44/77 chambers out there..I guess they had to allow for them being chambered in various rifles. I'm happy with the case quality and the fact they make the brass in the first place but a little disappointed they dropped back as much as they did. I'm all for supporting U.S. manufacture ( and Australian when it applies ) but for the 2 7/8" , I'd be inclined to get some Norma cases at 2.9" and trim only as much as you need to chamber.. then check again on first firing and you'll probably have cases happily chambering at 2.875" ( or even a tad over ). I guess they arent likely to change their settings now that they've done a run of brass...but a word or two in their direction wouldnt hurt for any future runs they do. JMO.

I balked at buying it because my chamber is 2.881 ,I thought that just a tat too short

I know what you mean Dean. I've since sold my 45/110 to a good friend but my last loads were made using Norma brass trimmed back to fit the chamber. I was trimming to 2.886". There was not much to take off the Norma cases and they worked beautifully in the gun. Chambering rounds with brass at 2.865 is putting one 20 thou off and I would think best avoided if possible. Depending on I.R's chamber..I'd be guessing he could probably have his brass at a similar length of 2.880- 2.885 or so...but only he can determine this. My 44 happily takes cases to 2.270 but I wouldnt be recommending it as a start point for anyone.

I'm changing all of my brass I use in my .44-75 Ballard and the .44-100 St to Norma Brass. I have yet to have a case fail short of smashing a couple during reloading them I bought for the .45-120 (3-1/4) 18 years ago that I now cut down for the .44's. It is good and very consistent brass. I also like the tapered heads for closing the breach on a tight fitting round in the Sharps.
