I have Quick Load but not Quick Design. I like the idea of the old, large, rimmed cartridges but obtaining brass can be a difficult and pricey proposition. It looks like 50-140 Sharps brass can be found within reason.

Would someone be willing to neck down the 50-140 to .458 and give it a neck about 1.5x caliber? I could then import the data file and tinker with it in QL.

Thanks,
Eric

I hate to be that guy, buttt... What you describe sounds an awful lot like the 450 no2 Nitro. And it's gonna be hard to take advantage of such a large case using smokeless. You're pretty much limited to the ruger #1, a Japanese miroku higwall 1885 or one of the bespoke builders if you want exceed ~40k psi.

450 #2 nitro

Is this what you're thinking of?


It's very much like a number of old Express cartridges.

wookie76,

Yes, it should be very much like the 450 NE No.2 but the cost of 50-140 brass is a heck of a lot cheaper than 450 NE No.2 if and when you can find it. Buffalo Arms carries is on a regular basis.

MickinColo,

That's exactly it. Does QD make a cartridge data file than can be imported into QL?

Thank you very much,
Eric

This is interesting, I have never tried to share a QD file with anyone before. I guess I can email the file(s) to you, then you can save them to a folder and see if QL can open them. PM me.

Ah so, I didn't realize what phase of interest you were in...

Wish I could help further, but I cheaped out and got Load from a Disk instead of QL. It's very close, but it denominates pressure in CUP, workable but probably not the better choice.

I think I may have been misunderstood. I don't know if you will be able to open it with your QL without having Quick Design installed on your computer. I'm willing to send it to you. If you can open it, great, if not, it didn't cost you anything.

That could be pretty sweet in a Ruger #1

I concur that it would be a good Ruger #1 cartridge but I'm thinking double rifle. Probably 480 gr @2050-2100 fps. For the time being a #1 is probably closer to grasp than a DR so that may have to suffice.

If keeping costs at a minimum but packing plenty of panache a rechamber of a Ruger #1 or Sabati would be the knees of bees. Maybe a Luxus single shot with its ease of barrel swap.

45-120 nitro. Basically a 450 ne with thicker rim. Norma brass is stout and cheap I am already started on a double for it

jeffeosso,

I agree that the 45-120 will do the same job but the 50-140 necked down is visually more appealing to me. I would like to know more about your 45-120 double. I had looked at the 45-120 at one time but that's another story.

The 45-120 nitro and the 450 are capacity twins. A reason why guys used the#2 to rechamber pedersolis is because the rim on the original 450 is thinner than the 4570

When you do all the math. Not just pressure and bolt thrust, the slim 45-120 ne makes the geometery of the block or lumps far easier

I am building mine in a huglu 12ga

I built a 550 flanged on a jana 12 ga once.

Maybe should go with the 450 #2, it would be much easier, less
time, much cheaper. The reason I say easier and cheaper is that
Captech Indusries/Jamison Cartridge has 8-9000 of them..

May I ask why you want a bottle necked case vs a straight tapered case?
I believe the latter will give longer case life and reduced need to trim cases.
In a Ruger #1 you can have velocity of a 460 Wby!

Seems like a lot of expense to avoid brass cost. Get a good handle full of #2 brass and loaded to your pressure it should last a lifetime. Not like it is an auto kicking the brass into the brush.

D R Hunter,

It is not really for any practical reason but more for aesthetics. I like the looks of the 450 NE No 2 but brass is a bit problematic. I have a 450-400 and like the "looks" of the cartridge and have been considering getting something a bit bigger in bore.

Eric

ramrod 340,

That is a good point. If no one had done this then I would have to pay for a custom reamer and custom dies. The additional cost may offset the "savings" in brass. I hadn't really put pencil to paper to quantify the additional costs to see if it warranted "saving" money on brass.

Thanks,
Eric

Hi ELeeton

Are you still playing with this idea? Don't let the nay sayers discourage you.

As far as I'm aware you don't need a data file from quickdesign to do what you are doing. Just pull up a similar cartridge in quickload and change the cartridge name, "case capacity" (grains H2O) and "groove caliber" to suit what you are doing. Then save these changes under a new file name. I'm sure someone will correct me if I'm wrong here.

With the 1.5 x cal neck length it sounds like you want something similar to a 500/450NE rather than the 450 No.2. You have quickload so you can see in the drawings there that the 500/450NE has a case head dia of .573" compared to .551" for the 50-140 sharps case. So a bit narrower but should give you the shape you want. You could pull up the 500/450 file and modify that or you could pull up the file for the old 45-125 Winchester (45 Express) and modify that. It has a bottleneck case with a longish neck and a case head dia of .533".

Getting the correct case capacity will be the hardest part. You could spring for 20 cases and form them and measure yourself or have a play with this online calculator to get a rough idea.

Rhodes,

I'll have to look into this once I get back home. Thanks.
