Starting to load for Francotte .470 NE

All:

Need some thoughts and suggestions on loading up for the .470 NE. I have been loading for both the .500 NE and .577 NE, but now looking to develop loads for my new Francotte .470 NE made in 1927.

Can anyone offer some good suggestions? I like RL 15, but hear guys get good results with H4831SC.

Will a filler be needed in either of these two powders?

I will be shooting the 500 grain woodleigh SPs.

Thanks in advance.

I should also note that the Francotte does not have any info on the barrels to say what bullet weight or powder charge it was regulated with, with the exception that it was regulated with solids.

So, does anyone have any knowledge of what bullet weight .470 NE were regulated with in Leige in 1927???? Is a 500 grain bullet a safe assumption?

Paul,

You will need a filler with RL-15, no filler with H4831SC. The Federal load is 87.5 grains of RL-15, with no filler but the special, hotter primer that they do not sell to the public. In my Evans, I have been using 87.5 grains of RL-15, a Kynoch foam wad, a Federal 215M primer and 500 grain Woodleigh solids.

Paul,
I would start with 85 grains of RL 15 with 500 gr Woodleigh Softs and work up.

I use Federal 215 Magnum Primers.

You MUST use filler, as you know.
I like a foam plug cut out with a sharpened [with a chamfer tool] 50 BMG case.

Dacron poly will work fine as well.

Once you find the right load with the Softs, drop 3 grains and start with the 500 gr Woodleigh Solids.

For a deer/pig load get some 350gr Hawks with the .035jkt and start with 75gr of IMR 3031 or just use the same powder charge of RL 15 that works with the 500 grainers.

Paul,
I would follow Tony's recomendations. In my Searcy 89 grains of RL-15 works...but so does 85 grains.

I don't care for the Hawk bullets in my doubles...they do funny things in full power loads...I have never tried the 350 grain though.

I would start with the loads that JJ used. And see how they shoot at 50 and 100 yards. I would shoot them over your chronograph to get a base velocity. Next the fun begins as you try to duplicate them.

Paul, my Merkel shoots absolutely great with 89 gr of RL15 and the Kynoch foam plug (500gr bullets). The #'s are a little faster than in 1927, I think....2200fps. I like the suggestion of using about 84-85 gr and work up...with the plug. The most consistent loads I got were with the combo mentioned.
I'm going thru the same thing now with my 450 NE....RL15...w/o a plug seems best so far.
450 case is smaller and Wright says no plug needed in 450 on down.
You will not need foam with 4831, but mine didn't shoot as well, and I personally think she kicks morewith the 4831 loads.
Good luck.

I like not using fillers so I went with 107-108 gr H4831SC.
