John,

You must be using my other work e-mail, as I haven't recieved any. If you just reply to the last e-mail I sent, it should make it through, either that or use my hotmail.

Hey John,
Are you hiding something from the rest of us about this rather obscure cartridge?

Good Hunting,

I just bought a "Cartridges of The World" and was looking at it.

Paul, how are you going to form cases for it?

I had trouble emailing Paul, I had the wrong address.

His 350 Rigby Magnum Rimless is chambered, I will test fire later this week.

Cases may be made from 375 H&H, turn the belt down, recut the extractor groove, trim, run in the size die, and fire form.

Paul's is on a CZ24 that he extended to the front. I think the ideal action is a Mark X Mauser, as the standard length Mark X has a magazine well opening in the receiver that is nearly 3-5/8", and the bolt is pretty far back when open. The magazine is made short to the rear, so just extend it rearward, do a little rail work at the rear, grind the bolt stop a touch, and you have it. Note, this does not require grinding away the front ramp as is done on the 375 H&H length Mark X.

Paul had 3 "real" 350 Rigby cases, with a 250 grain RN bullet, they feed fine out of a Mark X, and out of a pre 64 M70, and also out of a Classic M70. So, we have several actions to pick from.

The 350 Rigby Magnum Rimless is a nice compliment to a Mauser. Sure would make a ideal plains game rifle.

John,

A dandy plains game rifle it would be!

Do you think the 350 Rigby would work in a Ruger M77 Tang safety model 338 Win Mag? What performance gains is Paul going to get over the Whelen AI? Will it equal a 358 Norma Mag?

I have been waiting on Paul's progress, I think it would compliment my 35 whelen's. Possibly a 358 Norma would be better but I was thinking of a classic cartridge different from all others.

Case capacity is slightly more then the 358 norma mag. My goal is not increased velocity, but decreased pressure. I also like the way the gently tapered case will feed. With essentially the same capacity as the norma, there is plenty of loading data to go by as well.

The real downside is the brass. The only brass available is Bertram, which is soft, and outrageously expensive. Then again, making it out of H&H brass requires cutting down the rim, extractor slot, cutting off the belt, trimming to length, and neck turning.

I plan to load 250 gr @ 2700 fps, but figure if one was looking for plains game, a 225 gr @ 3000 fps would be a pretty decent load.

PaulH,

I happen to know someone who has original Kynoch ammo in 350 rigby, if you help me with my quickload request on the reloading forum, I will ask him how much he wants for it I think he might have a hundred rounds or so.

RE M77 Tang Safety Ruger: Magazine box is aound 3-5/16", which is too short for the 350 Rigby Magnum Rimless, COL is around 3.500" with a 250 grain RN seated at the cannelure. And it is a push feed! COL is longer with spitzers and X Bullets. And you need to start with a '06 bolt face and open up, the magnum bolt face is too large.

Easiest action to build one on is a Post 64 Classic M70. Put in a 375 box and follower, shorten the bolt stop and ejector, mill the rear bridge, open the bolt face, and you have it. Next easiest is a Mark X Mauser, noted in above post. Rigby used magnum length Mausers. Or use a Montana M1999.

This should be an awesome cartridge with X bullets, Swift A-Frames, etc.

1894,

Thanks for the offer, but unfortunately I don't have a copy of quickload, so can't be of assistance. I also believe shipping ammunition from England would be near impossible.

Strange how our regulations work, one can pack loaded ammunition in ones luggage, but try and ship the same ammo, and it becomes a hazardous material, with many regulations and limitations on how one can ship it.

Tried to post a photo of the 350 Rigby with other 35 cal. cartridges so you gents could see what it looks like, but www.huntingpictures.com does not work for me anymore when I try to upload new photos.

Anyone interested, email me and I will send the photo.

I�m not sure if Rigby sounds better than Brenneke ...

If you can make brass by turning down the rim on a H&H belted, you may also use 9.3x64 cases, as this is how they were made originally ( not manufactured, rather designed ).

This directly leads to the question if that rifle could not be chambered in 9.3x64 from the beginning. A factory cartridge, yes, but a rare one ... Coupled with A frames it must simply be murder.

Forget my writings. But if my idea is correct and you have a friend in Germany or visit there sometime buy a couple of cases and save yourself some work.

PaulH,

Only kidding re the quickload. I will nevertheless ask him how much he wants for it as it should at least be possible to pull the heads and deprime. Surely then they can be shipped? Of course I could allways bring them over on the way to some PD hunting....

I have another photo upload site to try tonight, the photo has 6 other 35 cal cartridges (all different) alongside the Rigby and is interesting viewing. I call it the "35 Lineup".

If all fails I will post it on my web site.
