Jamison .45/110 brass

[Ironramrod]

I bit the bullet and ordered 100 Jamison .45/110 brass. It is good looking brass, and about 0.011-0.012 thick at the case mouth. It is also short; I measured case lengths of 20 rds. selected randomly and all were between 2.865-2.867."

The case count in the plastic bag was also off. In the bag was a piece of paper w/ 74 written on it, so I dumped them out on the bench, counted them, and the bag was 26 rds. off. They were very quick at mailing 26 additional rds. of brass to make a total of 100.

I can grow the case length easy enough, but it is a little disconcerting to have the case lengths about 0.010" short.

IronRamrod, are your cases made by the new guys running the company, or an old lot? About 6 years ago I ordered a box of 20 to check them out. They were are all short like yours, but also the diameter above the rim way way undersized.

I've heard that quality is better with the new manufacturer. I wonder if you got a batch of the old stuff?

Chris, following your excellent tip on case diameter, I checked out 1 of the new Jamison cases compared to 1 of the Shiloh .45/110 fireformed Buffalo Arms/Starline stretched cases I use. The Jamison case measured 0.499" diam. just above the rim, and the Buffalo Arms case measured 0.501" diam. at the same location.

When I ordered the cases from Jamison the lady I talked to indicated the cases were all newly manufactured, but couldn't give me a good answer on why they were 0.010" shorter than standard chamber lengths in that caliber. Might be a product liability issue w/ potential smokeless powder loads, although I can't imagine shooting smokeless in the larger cases

Thanks again for the excellent tip on measuring case diameters.

Forward to seeing how they work for you. Folks I know who shot the other said they fireformed just fine and worked well

When you fireform them and then full length size them, they will grow .009 to .011 after full length sizing. I would say that they are just right. Shoot straight, rdnck.

Well, I loaded up 5 of the new Jamison .45/110 brass yesterday using 90 gr. of my super mistake 3f/2f Goex express mixture fire forming powder and 550 gr. Brooks pp semi round nose bullets for a test. Wads were a wax paper wad next to the powder, then a lubed 1/8" hard felt wad, then another wax paper wad, then a rubberized cork wad, and finally the patched bullet.

Before loading the brass averaged 2.865" in length; after firing the cases averaged 2.855" in length. After full length resizing w/ a Lyman FL sizing die the cases averaged 2.867" in length. The cases did grow a little, but not very much.

The target was 1 of my "sight-in" rocks at just under 100 yards about the size of a car hood w/ a dark spot in the center. The loads did shoot very good, despite the short cases; however, I've never seen paper rings that big either.

Maybe I omitted something really important in the loading process, and if I did please enlighten me.

the simplest way to prevent paper rings is to use 1F powder, almost sounds too simple ,

I normally shoot Fg black in the .45/110, but I was just using up some of my "fire forming powder." This blend was accidentally created several years ago, when I mistakenly dumped about 1/2 of a powder measure of 3F Goex Express into a half full can of 2F Express. That was one of those days where I couldn't hit the ground w/ my hat. Uff da!

I too have had days like that.... Uff Da is right
