I recently purchased an original NWMP '76 carbine, and intended to start reloading for it.  I don't want to use Black Powder.  I have the brass and 350gr. bullets.  I want to use a safe smokeless or Pyrodex load.  Please offer your suggestions.

They like blackpowder .......they really really like blackpowder !

I wouldnt use pyrodex in anything I value due to its rustability index 

Plenty blokes here have smokeyless loads that work - I wuzgunna do that - but the black worked really nice so I didnt go there .

These Ubertis clean up slick as a whistle after blackpowder - the cleaning really is a cinch -

I would think very carefully about using anything besides BP in an original mountie carbine...  Your choice, of course, but I'd think carefully.

When I read about peoples loads, I don't know if they are reloading for a new Ubirti gun or, for and old iron gun like mine.

You just got the best and safest advice for an old iron gun. Black Powder only. It's your gun but why would you even risk getting hurt or destroying a piece of history? Besides you can't get anywhere close to the same enjoyment shooting smokeless and black powder is the only way to get the full experience of shooting a historical gun made for black powder.

I passed on a Lyman mold/mould (how does it get really get spelled, I see both ways?) (Lyman 457191 Single Cavity) on ebay. Price was $70. Would that have been a good mold for the 45/75? no bids, so I'm watching to see if it comes back. I didn't bid because I thought the 457 part is the diameter? Is this number the strict diameter or will the size fluctuate with different alloy?

I use a mold/mould (both spellings are actually acceptable) from Accurate Molds which I like a great deal. It casts closer to 350 grains.

Before investing in that Lyman mold, you could try some from Montana Bullet Works. I've never ordered from them, but I hear good reports.

[Black River Smith]

It is correctly spelled 'both' ways.  Lee uses 'Mold' on their boxes and Lyman uses 'Mould' on their orange containers.

To answer your second question - that would have been a good price for the 457191 new mould.

To then answer your third question - No.  The 457191 is the bullet for the 45/60; 45/90 at 292grs..  The proper bullet for the 45/75 is # 457192 at 350grs..

To your fourth question Yes for Lyman the first three numbers represent the diameter.  My 457191 mould drops at 0.457 for the original 1 to 16 tin/ lead alloy.  I could leave it as is since I shoot smokeless but I size to the correct diameter of 0.456.  Your uberti rifle may have a different / larger groove diameter.  Lyman listed, at one time, a 456 and a 457 for both the 191 and 192 designs.

For the last question 'Yes' you can and will see slight variation in diameters with different lead mixtures.  That is why most cast bullets need to be final sized to your desires or firearm needs.  You may need to buy from different companies to get a large enough mould to cast bullets, you need.  The 44 calibers are notorious for different chambers and bores.  My first Lyman 45Colt mould was a new 454190 but that mould only dropped 0.452 size bullets.  I was not sauvey when I first started to cast, therefore I did not catch this size difference for a time.  I later bought an older model of the 454190 and was happen to measure a 0.454 bullet.  MY 45 Colts firearms had true 0.454 barrels not modernized 0.452's.  So be careful and get a good caliper if you do not already have one.

Would a neck sizing die for a 45/110/120 work for neck sizing the 45/75? I'm not real happy with the way my CH4D die sizes the neck. Mine is the Uberti chamber, just seems like there is not much bullets tension. With .458 bullets, sometime falls into the case. .459's stay put, but it doesn't feel like its very tight. Die is all the way down to the shell holder.

Which Accurate mold number is that if you don't mind me asking?

[Coal Creek Griff]

He has several similar designs for the .45-75, but the one that I have used with my Uberti carbine is his 46-345LC:

CCG, is your's the Uberti Chamber?

[Coal Creek Griff]

Mine has the newer Uberti chamber which is very similar to the original Winchester.

I've  owned a bunch of original '76 carbines in all calibers, including .50 Express.  The .45-75  has always been a favorite.  I took my son-in-laws out last weekend and let them shoot a .45-75 carbine and a .50 Express  rifle.  What a blast.  I never use smokeless in any of my original 76's.  You are asking for trouble.  In the .45-75, I  use 4.3 grs. of 4227 on the primer and 67 grains of 2F black, with a card wad on top.  My cases are reformed 348 Winchester, so this is a compressed  load. I use ONLY 350 grain bullets with SPG blackpowder bullet lube.  The blackpowder lube and the 4227, help keep the fowling down considerably.  Always use soap and water to clean the bore and turn the gun upside down with action open and carrier block up, flush with the bottom of the receiver.   Much easier to clean and no residue  will drip into the action, if done right.  Good luck and have fun.
