45 110 case length

Post by Coltwcf44 »

Hello all and Happy New Year,
I ran across a 45 110 Sporter #1 that I had to have. It came with 75 Jamison cases. I ran them through the tumbler and sized them. Case length is mostly around 2.868, a few at 2.872 and some short ones at around 2.861 with a couple at 2.857. I also have 50 of the stretched 45 100 Starline cases from Buffalo Arms that measure mostly 2.868. So what case length is best to start with? The Lyman book says trim to 2.865, but is that for smokeless since that's all they list for powders, or is it the same for black? Any ideas and help appreciated. Thanks

I thought I would get asked that. I dont know. Haven't done a chamber cast. I might as well ask, how is that done?

You want to measure case length preferably with fireformed brass, not with sized. Sized will be longer.

You could trim the long ones to the same length as the Starline and give them a whirl. But make sure you check them again before you reload the next time just to see what's going on.

They should be

2.880 for PP and nothing shorter than 2.875.

For what you want to know a wax cast will do just fine with out doing any damage.
Get some Paraffin wax or use B wax if you have it. Lightly oil the chamber and bore and push a couple cotton balls or patches lightly oiled just ahead of the chamber and pour some melted wax in.
Before you trim those cases fire them first and get your measurements so you don't trim them too short.
I trim my fired cases .005" short.

I agree, get your chamber cast and measured then your brass will be right for your gun.

If it's a Shiloh then follow what Kenny says. Those numbers work in mine.

2.875" has worked for years in mine with no issues with an occasional trim. Its a early Shiloh B serial number gun.

This is good advice.

My chamber was cut with a Loomer reamer patterned after the originals, it's tight and not made to shoot greasers like the originals. It's 2.881" long and after fireforming that is where I leave them with a std chamfer on the outside and a VLD chamfer on the inside, Norma brass. When you have the setup like I have, you only ever have to size to fireform once. That's it, after that, it's deprime , clean and reload just like the originals. The case length doesn't grow like rounds sized every time for greasers. While I'm ruffling feathers I'll add "Norma brass is the best, blow off the rest". 2019 is soon behind us I am glad to have the chance to offer this advice for the well being of other 45-110 shooters for 2020 and beyond. Have a happy New Year. bobw

the good thing about low transition angles like 7 and 4 degrees on proper chambers is that if a case is a bit short, it matters little.

That's how a lot of military rifles of the day were configured - very gentle, long transition to the bore. Even longer cases will be swallowed without mishaps.

I started the original post and now have some numbers for the veteran shooters to comment on for me and let me know if I'm on the right track. Oh, and by the way, thanks for all of the replies. You have all been a great help. Again this is some fired brass that came with the rifle and it appears to me that it was loaded with smokeless. Its Bell brass not Jamison which I said it was in the OP. My bad there.

Fired Bell brass cases measure mostly 2.868. I trimmed the few longer ones to this length.
535 gr Lyman Postell bullet
Neck tension .002
Chamber 2.881
OAL with bullet touching rifling 3.677

I haven't loaded any powder yet just been working with one dummy round. How do these numbers look to you all? Any recommendations for a starting load for powder and wad? I have Old Enysford 2f and Swiss 2f on hand. My bullets haven't arrived yet, and I'm not casting as of yet, and I only have this one 535 gr bullet that was mixed in with the order of 500 grainers I received awhile back. At least having it I was able to set up the dies and get some measurements. Kinda sounds like Barney Pfeif, though. Let me know your thoughts.

Thanks again,
Coltwcf44
