RE: 44-77 Sharps paper patched load
All ..very sound advice Eric. I do believe its the rifles 'gestation' period that causes some ( read 'me'  ) to play around with loading before they have their rifle to test chamber. Been there...done that  . Looking forward to your foray into the realm of the 44's and your feedback along the way. I couldn't quite bring myself to order a period correct chamber but I've no regrets on the cartridge choice and Shilohs now standard 44/77 chamber is a pretty good place to start. Sounds like you're getting a handle on the brass now and be interested to see what your fired brass measures up at once you've fire formed. I'm not sizing my case necks much at all but being a gg chamber, albeit a tight gg chamber, I am sizing a little , around .464" but only down to about 3/10" of an inch. They are almost a slip fit. Fired cases run necks at .467/.468". I'm guessing you'll probably have none of that sizing business to worry about once you've fired your cases. Decap, wash, polish maybe and then load again. All sounds good. Enjoy.

RE: 44-77 Sharps paper patched load

I could not wait any longer and got to the range today to fire a few rounds from my 44-77. Nice Chamber! Dimensions are: Factory base@.517/.518, Shoulder @ .506/.507, Neck@ .458/.459, Mouth@ .460, Length@ 2.243 and Rim Thickness@ .075 Fire Formed base@.517, Shoulder@.510, Neck@.459, Mouth@.459, Length@ 2.240 and Rim Thickness@ .075 Not much change at all except for Length. Only a loss of .003. The inside diameter at the mouth is just a very little loose for seating a new bullet and will require a slight neck sizing to work properly. This is going to work really well!! If I can get some weather I'll finish fire forming the first 20 rounds next week and then put up some reloads for a initial test. Did I say I really love this rifle?

RE: 44-77 Sharps paper patched load
Thanks for the measurements Eric. Sounds about right then. The rest of the case is pretty much in line with the their current gg chamber other than the as expected tighter neck dimensions to better suit ' patch to bore ' loading. On average my fired cases are .515" at the base, .509/.510 at the shoulder and the neck and mouth at .467". Case length dropped back a bit though and 2.241 - .2.247" being average. With that stepped out shoulder I guess the brass has to come from somewhere. Some rims are as low as .071 and others up at .076" . Having said that though, once fire formed and only neck sized, I've had no issues and very happy with the Jamison brass. Nice to see those photos of original cartridges too Kurt.
... Funny..just thinking those before and after shots Eric... if you didn't know what they were... could almost be .22 Hornet and a K Hornet 
rgds.. J.B.

RE: 44-77 Sharps paper patched load
I think the reason they did not shorten more and I also noticed this shooting my new .44-77 and .44-90 bn Jamison brass that they did not shorten much. I think with the long taper the new unfired brass shoulders have that most gets pushed forward on the first firing.
I think you will also find that even with the long taper the accuracy does not suffer. When I got my new batch of cases I just worked with 50 and did the ladder load developing a good load and when that load was used in the unfired cases they shot just as well as the formed cases.
