44-77 brass

RE: 44-77 brass
Your more than welcome to try them in either/both twists, if they shoot ok in the 19 they should shoot very well in a 17. From an earlier post from Mike they seem to shoot ok in his 19, but he hasn't put it on paper, if I understand correctly, he has only shot it on steel out to 800 or so.

RE: 44-77 brass
Hopefully should have some of this new Jamison/Captech brass soon and fingers crossed..it will actually fit with minimal additional machining. I've been using some RMC brass up until now and been very happy with it. Tom and family at RMC have been a great help. The bonus of course with this is being able to order the neck thickness you want...which may suit some chambers more .. especially if paper patch is anticipated. Obviously a 'traditional chamber' makes it easier again. The chamber on this 44/77 is very snug indeed..and so far... I'm loving the 7 degree lead. Fired cases are coming out at .469" at the neck ..and dont like being flared much at all. All told..pretty impressed with this 'little 44' ! Big Grin

Kurt had mentioned to me about maybe having a PPB made up following the nose design of the Accurate bullet I have, 44-480S. Here is what that bullet would look like.

I like that nose radius.

RE: 44-77 brass
Here are a couple more bullets for you all to take a look at. All I have done was to increase the nose radius by .05", by doing so it also increased the nose length a little. I have also revised the original drawing that I had posted to include some more measurements so that things can be more easily compared.
I have also received a reamer drawing from Pacific Tool & Gage for the 44-77. They sent it to me as an XLS file but just to make life easier for everyone to view it I converted it to a pdf. If anyone would like the XLS file, send me a pm and let me know where to send it and I will gladly pass it along.

RE: 44-77 brass
I think you would be much happier with the diameter of those bullets at .433-.435 depending on the intended use. .435 for target work wiping between shots, .433/4 for either general shooting or target work.

RE: 44-77 brass
Sam,

I have bullet similar to the 80-R that has a .180 meplat. The radius is just slightly longer and the diameter is .4307".
Your bullet with a .060 deep cup cast @ 1/30 L/T will weigh close to 480 gr and with a flat base it will be close to1.305" long with the same 480 gr weight judging from my bullets of similar profile.
This is a great shooting bullet in the .44-77 and also the .44-90 bn with the 1/19 ROT and also in my 1/17 ROT in the .44-100 Rem st.
I like the .430"-.431" for a hunting bullet for a fouled throat follow up shot. First shot clean bore patched tight and the second patched loose. This diameter I can adjust with the paper I have all the way to have patched the bullet slightly over bore diameter I like for match.
I'm getting ready for a second bullet like this with a meplat about the size of your drawing for a hunting bullet with a 1.320 flat based bullet with a .225" meplat for the .44-77. I like the slightly longer radius to hold the patch a little farther back on the shank and slightly farther ahead on the radius to keep the bare lead from making contact with the bore when the nose gets setback using the soft alloy used for a hunting bullet.

RE: 44-77 brass
Don I pretty much drew them up to see how they would look. Diameters and lengths can be adjusted to individual tastes. To increase the diameter a few thousandths, will not make much of a change in the nose length. If you would like I can draw up one with the diameter and nose radius of your choice and post it up. I think it takes me about a half hour or so to draw up one of these. And I could use the practice with the CAD program. I don't use it enough and I forget what some of the buttons do and there are a bunch of them.

RE: 44-77 brass
Thanks for the offer Sam, but I think with the number of moulds I have on hand now for the 44 I'm pretty well set. That's one of the big perks of the Eysnford powder ,the lubed felt wad and jojoba on the exposed patch. I can shoot bullets quite a bit larger than previously possible without wiping. The dual diameter bullet copied from that original sharps bullet that Old West made is a real gem in that the base at .435, and the nose at .431 gives the bullet base good purchase on the rifling and the skinny nose allows loading in a fouled chamber, and the dang thing delivers good accuracy. Thinking serious about having Brooks cut me one with a fixed 1.3 inch length, but I also like that hollow base... but for now I'll just be happy.

RE: 44-77 brass
Courtesy of Captech, BACo and a few additional 'links in the chain' .. I took delivery of some Jamison brass yesterday. A few hundred cases should keep me out of trouble for a while. As Don indicated... I expected a more pronounced annealing mark but I gather from previous entries that they have been done ? Picked twenty at random and all are chambering without any effort or reducing of the rim thickness. For those that may be interested.. of the twenty measured.. rim diameters were .624- .626", rim thickness .072 - .0755"..with one at .069". Average was around .0745". Case length at 2.250 - 2.252".. once again...one at 2.239". Neck thickness of .009 - .0105..with .010" as an average. Fairly tapered overall but one range day will have them nicely fire formed . A little relieved now to actually have some more brass to work with ! Smile
