No disrespect to your gunsmith, but it shouldn't take 60 hours to get one to feed. Two things are needed: 1) The strongest magazine spring you can find for a Mauser, and 2) The proper angle on the feed rails (both front to back and bottom to top). -Lee www.singleactions.com |

There's another trick you can do on the 425. Form the brass off 404 Jeffery and leave the rim un-rebated. It requires the bolt face to be opened, but other than that it's a simple fix (and 404 brass is much more plentiful). -Lee www.singleactions.com |

Hi
We looked on the possibility to use 404 cases but in the end i wanted to use the original case, more fun that way. As for those 60 hours i mentined earlier, they could have included the fitting of the magzine extension, it has been foyr years so my memory is not the best.

For bullets this is just a WAG, but what about lathe turned copper or the alloy of your choice, solids? With pressure relief or flow grooves & maybe even tumbled in moly disulfied powder. Is this idea workable?
Whatever you work out, it does sound like a fun project.

I have a tracer lathe and could make my own out of copper stock. Would prefer to buy lead core slugs....making my own would be a last resort. My dad and I have talked about turning solids for our 50 BMGs. May try it over the winter if I can get enough copper at a reasonable price. -Lee www.singleactions.com |

I don't know if you started this project yet but the feed issues were real problems on the rifles issued to game rangers. This was more a product of poor design on the conversion magazine than an impossibility to make feed. Hawk bullets work jsut fine as long as you go heavy enough on the jacket. Andy will make them with a .050" jacket that are more matched to the velocity. reflex264

There is a good writeup in the 1981 Gun Digest by Jack Lott. Explains the feed problems.

Hi Lee Martin
I'm sorry too say that i totally missed your question about bullets, but Woodleigh and Hawk is the only makers i have found so far and I'm not impressed whit Hawk but i have only used the ones whit.035 jacket thickness and that combination failed too penetrate a moose calf, i found the jacket, no lead at all under the skin opposite the entry. It weighed about 50 kg

I won't try to talk you out of it. For a long time I've been interested in the big sporting rifles of days long past. Never owned anything larger than 375 H&H, and so far have settled for collecting specimens of the larger catridges.
I will watch your project with keen interest...........

Lee,
Sent e-mail with link to Hawk Bullets. They make 8 bullets of different weights and jacket thicknesses.

Hi Lee,
I am new to this forum, but having read your posts about building a .425 WR Magnum, I thought I would post my experiences with the rifles and cartridge.
First of all, it is a great cartridge. Don't let anyone try to tell you differently. It was one of the first truly modern smokeless powder magnums and was not developed to be cheap or a poor man's cartridge at all. It was developed to be a primary cartridge for the professional Ivory hunter; and it was one of the best.
Back when the cartridge was developed, there was much controversy as to the benefits of a rebated rim (there still is) and the prevailing sentiment was that the advantages far outweighed whatever difficulties the design forced on the gunmaker. Issues like lower back thrust against the bolt face while still maintaining high CUP was only one of its advantages.
Currently, I have two 425's that are as good to look at as they are to shoot. One was made for me by Westley Richards and is engraved by the Brown Bros. The other was made for me by Mark Silver and is engraved by Robert Swartley. Both function and feed perfectly, whether the rifle is up side down or right side up. Recoil is considerably less than a .458 Win Mag or 416 Rigby producing the same energy.
While it is true that during the hey day of the African rifle trade, cheap rifles, especially from the guilds of Europe, were produced that did not function as they should, this was due more to the cheap quality of the rifles than to the design of the 425 cartridge. A cheap rifle is a cheap rifle and should not be compared to those being hand made by some of Englands best.
Anyway, I hope I haven't bored you with all this. I am glad to hear of your admiration for the cartridge. If there is any info or contacts I can send your way, let me know.
Respectfully
Dennis

Groo here
If you do a search I think Savage chambered a rifle for it at one time.

Savage chambered the 425 Express. Basically a 300 Win Mag necked up to 425. I still haven't started this project, but have a nice CZ24 action waiting on the shelf. -Lee www.singleactions.com |
