nitro express load data

[Devin Callis]

Hey I know this might get be a long shot but does anyone have any reloading data for .450-400 NE for north fork bullets?

f you have, or can get your hands on, African Dangerous Game Cartridges by Pierre van der Walt you will find pages of consolidated, attributed loads for the express cartridges. Worth the investment if you can find a copy.

If the above does not work you can find on Amazon for a Kindle or Fire. It is a book worth having or the download for reference.

Second thought the Woodleigh reloading manual will do it.

Everything in the previously mentioned book is irrelevant when it comes to North Fork bullets,.....Aside from the safe powders to use in any given Nitro Double, which appear to be in this country RL15 and H4350. If you use the nitro conversion formula that gives you a pretty good starting point. I faced the same situation loading for an old english double and NF bullets, but I have a supply of Woodleighs that are dialed in so I abandoned NF. I will say because of the design of NF they take more powder charge to get to needed velocity.

In my case I wrote to NF for loads, and they were quite prompt in providing for my caliber

3" or 3 1/4"
Proofed for 60 grains of cordite?

If your rifle is 450-400 3" I wrote the following in a previous post about regulation loads:

In my Merkel 140AE, the Hornady DGX factory load shoots about 2040 fps, but varies from 2000 fps in near freezing temperatures to 2080 fps in hot temperatures. There is also a difference of about 30 fps between the two barrels. My rifle regulates well at 50M with the Hornady factory load.

The Woodleigh 400 gr. SP regulates well with 80 grains of IMR 4831, Fed 215M primer @ 2010 fps. Increasing the charge to 81 grains of IMR 4831 yielded about 2100 fps. and slightly more open groups.

If substituting Hodgdon 4831, my rifle requires 83-83.5 gr. of powder & Fed 215M primer for similar velocity and group size.

When loading the North fork Cup Point Solid, or the Woodleigh Solid, I drop down to 81 gr. of H4831.

I have both African Dangerous Game Cartridges by der Walt and the Woodleigh Bullets loading manual. I will attach pictures for the 450/400 load data from these books as well as the data from Shooting the British Double Rifle by Graeme Wright.

Longwalker said he is basically reducing his load by 2 to 3 percent for North Fork Cup Point Solids and Woodleigh Solids. Hopefully this

should give you a solid starting point.

Hey Devin, Jay with North Fork here. I'll shoot you a PM. Thanks
