full blown nitro
 

Just aquired my first double rifle today. It is a manton in 450x.400x3' nitro. Any body out there load for this caliber. Any info would be appreciated. Don't want to blow my self up. Or a very expensive gun.

You might post on the accuratereloading form. There are a lot of double rifle guys there.

Richard, that would be a 40 caliber rifle. Keep trying the nitroexpress website. If you are unsuccessful, PM me and I will give you contact information for CaptCurl. He is an experienced double rifle reloader and has an astounding collection.

That is a great all around caliber and can be used for some game in the U.S. unlike some other cartridges. I think the .450 range and up has very limited uses here. If you work up a load you should post your results here I would like to see if you get your load to match what it was originally regulated for. I

This rifle has a load worked up for it useing 3031 powder and a dacron filler. Load looks pretty good but I am not sure how much filler to use. When I tryed to enroll on nitro express they wanted an email address but it could not be yahoo hot mail or the like. I dont no of any other types of email. Dose anybody no what they are talking about.

I had a 450-400 3 1/4" H&H Royal grade sidelock, and it was a brutal beast using Kynoch ammo. I tried reloading it and the only loads that would shoot to the same point of impact were equally punishing. Since the only cases available used Berdan primers, and the Kynoch ammo was available, I gave up trying to reload it, and just shot Kynoch. The gun was overpowered for virtually any North American game that I hunted. I guess it would be good enough medicine for Grissly.
