Mold recomendation

[Rabbit]

Good morning forum,
I have put some money down on a reproduction 1876 rifle in .45-60. It is a used gun and it includes the dies, and some brass. I am planning on ordering a mold, I have two choices, the RCBS #45-300FN and the Lyman #457191. The RCBS mold is a gas check design, I guess you don't have to use the gas check, but I am asking if any of you pards have used either, and if you have a preference.
Thanks,
Rabbit

I don't have experience with either of those molds, but we should probably clarify the cartridge (.45-60/.45-75?).  Is this an Uberti or an original--it might make a difference.

I will state that I use an Accurate Molds mold for my Uberti .45-75 and I can't say enough about it--the mold is just about perfect.

Thanks Mr Griff,
I have fixed my original post. My rifle is a reproduction chambered in .45-60. My plan was to load both black powder and smokeless. The Lyman mold is a flat base bullet, but you have to crimp over the front driving band. The RCBS bullet has a crimp grove, but it is a gas check design. Both have their plus and minus points, I was hoping to get some advice.

   I have an original 1876 Winchester that has been fed nothing but Lyman 457191 292 grain bullets  lubed with SPG and powered by 2fg black powder only.   I have been happy enough with this load that I have not tried any other bullet.  I  would like to try 1.5fg  Swiss for  a little cleaner burn and perhaps a bit more zip.

Well, this may or may not help, but Tom at Accurate Molds can make you nearly anything you want.  If you want a modification of an existing commercial mold design (like adding a crimp groove to help with smokeless loads or making it with a plain base rather than cut for a gas check), it is particularly easy.  To be clear, I'm not talking about modifying molds themselves, but modifying the design and having Tom make the molds.)

Here's a link to a thread I started some time ago talking about bullets for the .45-75.  Again, it might not help, but it might point you in the right direction.  Take a look at the Accurate Molds catalog of designs.  They're all custom so if you don't see exactly what you want, contact Tom and he can probably make it for you.

Mr Coal Creek Griff, thank you sir. Good information, I ended up going with the RCBS mold, I will post a range report when I shoot the rifle.

I have not used either of those molds
Blackpowder you gotta have a mold that hauls plenty of lube - dont need a crimp groove
Smokeless you gotta have a proper and well engineered crimp groove and it MUST be in the right place so your overall length is in spec. Shouldnt need a gas check and I reckon a flat base boolit shoots better than a naked gas check base

The LEE 405 HB works fine in my Uberti to 200 yards and it hauls a heap of lube - its a good blackpowder boolit - casting is a little slow with it but no big deal. 
the Lyman looks like it is ok for your blackpowder mold -
RCBS ? ya wont NEED the gascheck but you will need a proper crimp groove for smokeless (I only shot black in mine - was gonna do smokeless - but dont think I will bother. )
If its a Uberti - these things can shoot!!!
