Recieved my 76 not completely satisfied

[BobinIL]

Well, looks like I will be going down the Repro 1876 rabbit hole.    Finally recieved my Taylors Uberti 76 yesterday and made it to the range today.  Looks like mine has the Uberti chamber and I don't like it.  Not only are the shoulder about 1/4" further up than the originals It bulges the brass about 1/2" from the rim.    How hard will it be to get Taylors to put a correctly chambered barrle on this rifle??

45-75  Just sent an email to Taylors since it is Saturday I will not be able to call them until Monday.

Frankly I do not know what your hangup is.  I have a large chamber in mine and have enjoyed it for about the 5 or so years that I have had it.  Just because it is not in tradition does not make it a bad thing. I have never had the rim/case head problems that you are experiencing and that would be good to check out but as far as the larger chamber goes, you get more case capacity and thus you are able to put more powder in.  My rifle likes 76 grains of Swiss1½ under a 350 grain bullet and does it very niicely.  Just takes some getting used to.  When I fire formed some 348 brass, for the first few reloadings there was some "coke bottle" shapes but they diisappeared after several reloadings.  You need to fire-form the brass to really be able to use in the larger chamber and after that--no sweat.

I fired two different loads today.  One was the Ten-X commercial load and the other was my reload of 25grns  of 5744 under a 350 grn bullet and a Federal large rifle magnum primer.  Upon further inspection I noticed the fired Ten-X brass had the coke bottle bulge and the reloads were nice and strait.  I will wait until I hear back from Taylors before I decide what to do but I feel better about the fire forming of the brass.  If I keep it as is I will just have to shell out for the custom Uberti chamber die set.

You will find that a Trim and File die will help emensly also.  In my fire-forming operations, I used about 16 grains of bullseye then cream of wheat for a filler and a beeswax plug at the case mouth.  Never lost a case this way and then annealed them in a pan of water on a lazy susan.  Got a whle bunch this way and with the larger powder capacity am pretty pleased.

well I ordered the 4D Uberti dies and now the next dilemma is when I seat the bullet the case neck will not hold the bullet tightly.  I can spin the bullet inside the case and if I put a bullet in the case mouth I can push it in with my thumb and it will drop all the way through to the bottom of the case.  My bullets measure .459 and I am not over flaring them.  I think my dies are not squeezing the neck down tight enough.  Using Jameson brass.

That sounds as to you have a die problem in that they may not have been machined properly.  Suggest you contact the folks that made them for advice.  That is not right.  I have not had that problem myself  but I betcha that they will make that right at no cost to you.  The only other thing to do would be to run them through the Trim die after they are loaded so they are squoze down tight.  That is if you have a Trim die.

If you NECK SIZE only, your brass will last much longer than full length sizing. It's the stretching back and forth between firing and full length sizing that shortens case life. Back in the day, they didn't even neck size either (as long as the brass is fire formed and used only in a particular gun). They just re-primed, charged the case, put in the bullet and CRIMPED the case. The powder kept the bullet from falling in, and the crimp kept it from falling out. If you load smokeless, use an appropriate filler. I use Quaker Puffed Rice.....it's shot from guns! Loading smokeless this way in my 50-70 M'66 Springfield, I get 2" groups at 100 yds. Just remember: load for accuracy, not power.

After a lot of xperimentation I ended up loading my .45-75 the way Joe says they did it in the old days. I use black powder only and a nice tite roll crimp and I get very fine accuracy and loading is a breeze.
