I have a ruger no1 that started out as a 458 lott, 3 years ago (yes i know, long time) i left it with a local gunsmith to rechamber it to 500 ne which then got changed to 50-110 (found another in 500 i purchased). Anyways, gunsmith recently passed and i now have a disassembled ruger no1 with a lilja match grade 1 in 15" .510 barrel chambered in 50-110.

Fairly certail the falling block still needs relieved for the rim. All thats been done is threading and chambering the new barrel

But my dilemma now is that 50-110 brass is currently unavailable unless i trust someone on gunbroker and dies are nonexistent unless i want to pay an exorbitant amount for them.

Figured my options are to continue with 50-110, put a new 458 barrel on and chamber for 458 lott again or i could get it rechambered to 500 nitro possibly? Other caliber ideas with the current barrel or?

If i went with 500 nitro, would i be able to just ream it again and be good to go or?

Anyone got some ideas/input? Not in a huge hurry but would like to finally finish this project and get it up and running for moose and bear and maybe Africa some day

Starline has 50-110 on backorder. It will be available at some point. If you were absolutely set on shooting your rifle now. 50 Alaskan brass is available several places (starline, Huntingtons and either midway or midsouth). You can long load the bullet and shoot just like a .458 Win Mag in a .458 Lott. The 50 cases are the same except length.
I can't tell you about the Number 1 gunsmithing as I don't own one.
As far as the 50-110m I have one in a Turnbull 1886 and it is a blast to shoot. I have a Turnbull 50 Alaskan Marlin 1895 which has become my favorite hunting rifle the last 10 years. I can tell you, that using a Woodleigh 535 or 570 that 50-110 will shoot length way through a moose and exit with a golf ball size hole. It will do the same to a bear. The Barnes 450 original is also a great bullet for this round.

The 50/110 shares the same diameter rim as the 45/70 and I’m pretty sure that size rimmed case will feed without altering the back of the action.

Turnbull recently had Hornady do a run of dies in 50/110.

I had a Ruger No.1 converted to 50/90 and that project turned out really well. The rim on the 50/90 is larger than that of the 50/110 and the back of my action did need to be opened up to feed the case. A 50/110 can be loaded quite heavily if that’s what you are after. Personally I’d continue down that path since you already have the parts.

might should cross post this in gunsmithing

I may be wrong here but here goes. I recently chambered a #1 to 220 Swift. With the swift having the semi-rimmed case and most rifles chambered for it being in bolt action with the correct bolt face, the standard reamer for the Swift, and I assume the 50 cal cartridges, does not have the reamer ground to allow for cutting the rim diameter in the face of the barred as is necessary with the #1.

Thoughts?

Yes the 50-110 and Sharps 50s of all lengths have the rim feature on the reamers. On the ones I have seen anyway. Since the 50-110 was designed for the Win 86 (it was not a single shot cartridge); it was an express round with a 300 grain bullet, it needs the rim recess. My 86 has a rim recess.
And yes this is a gunsmithing topic but too late now....

I would suggest going back to the 458 Lott, that way if your ammo is lost and your in the Selous or some distant place in the world, chances are you can locate some 458 win. to get you by..Its not allways about caliber, availability is most important..and frankly the 458 Lott is more buffalo and DG ready than the 50-110, 45-90 or whatever..

Don't know of they are still around, but Siegrist(sp?)gun shop built a 50-140 on a Ruger No. 1 I had.....
Found it. Under Siegrist Gun and Machine Shop.

I use a 50-110 Win.( It's actually necked down to true .500 cal, custom chamber.) in a H&R Handi rifle and in a TC Encore MGM barrel. A 410gr. CEB Raptor bullet at 2,000 fps kills cape buffalo DTR. In your No1 you could load it up to the low side of 500NE. Combining these "old west" cartridges with modern bullets makes a huge difference in terminal performance, as you probably know.

I love that 50-110 case. Brian
