Folks: thanks for staying with me.  Pstein/Bultlers/1staz, you are very helpful.  So, here's my plan -- something along the lines of "compare & contrast."  I'm going to start out with the Remington 180's. 

After tooling up, the first reload effort will be Hornady 220 gr round nose soft points with 40 gr.s of  IMR 4350.

Then I'd like to find a load with less recoil and good for 100 yard targets.  So, for my last question (for a while) to you is what is your recommendation for this?  Butlersrangers, you had a lighter bullet and lesser load in mind?  Anything specifically you can share?   

Psteinmeyer, would it work if I continued with the 220 gr bullet, but just backed off the IMR 4350 a little, to say 38 grains?  I don't know what that does to the physics of pressure?   I have IMR 4227 and IMR 4831 at hand.  Is there something with these powders that will give good results?

As a foot note, I presently reload for my Martini-Enfield and use a Hornady .303  [#3130] 175 grain round nose soft point.  I use 18 grains IMR 4227.  This is a very light load, but works perfectly @ 100yds with a minimum of recoil.

And for my 1896 Lee-Enfield Mark I use a .312, 215 gr Woodleigh RN and reload with 37 grains IMR 4831 (and sometimes 39 gr.s)  Again, good results at 100 yd.s   

I'd value your recommendations.
