We are starting to load for a 404J with Re15 and the following bullets: 400 Woodleigh SN and FMJ, 400 TSX, 350 Barnes X, 400 Barnes Solid, 380 North Fork. Any ideas?

Several Reloader 15 loads for 400 grainers on the reloading pages as well. http://www.accuratereloading.com/404.html

Oh, Alliant Reloder-15:

Powder lots seem to vary a lot with RL-15, so below is just a rough guide depending on your lot of powder
AND on whether you have a "loose" barrel or a "tight" barrel, as 404 Jeffery barrels vary too,
even nowadays, new-made barrels.

Chonography:

Norma brass, F215 primer, Woodleigh 400-grain RNSP
RL-15:

72.0 grains >>> 2120 fps
75.0 grains >>> 2227 fps
77.0 grains >>> 2290 fps
79.0 grains >>> 2360 fps

Above is in my 24" long, "loose" McGowen barrel of 1:10" twist and .425" groove-diameter.

If you have a tighter make barrel with .423" groove, you will get higher velocities and pressures than I did.

The CZ 550 Magnum in .404 Jeffery used a McGowen barrel like mine, 1:10" twist.

My rifle liked Varget best:

Norma brass, F215 primer, Woodleigh 400-grain RNSP
Varget:

72.0 grains >>> 2125 fps
75.0 grains >>> 2233 fps
77.0 grains >>> 2275 fps
79.0 grains >>> 2336 fps
80.0 grains >>> 2380 fps
81.0 grains >>> 2406 fps ... Best load in my rifle with Woodleigh 400-grain RNSP.

380-grain North Fork SP is best of all, Norma brass, F215 primer:
Varget 83.0 grains >>> 2528 fps

Some of the above loads were done on different days with different temperatures,
but I think you would be safe in any 404 Jeffery with modern steel action and barrel to start around 72 grains of RL-15
and work up to 80 grains of RL-15, with 400-grain Woodleigh RNSP.

The Varget is a tad slower than RL-15, overall in the 404 Jeffery.
Start with 73 grains of Varget and work up to 81 grains of Varget, with 400-grain Woodleigh RNSP.

I would expect RL-15 at 82.0 grains to give about 2528 fps with the 380-grain North Fork,
like 83.0 grains of Varget did in my rifle,
but I have not tried the RL-15 with 380-grainer.

Use one grain less powder with the FMJ Woodleigh 400-grain "solids" versus the RNSP Weldcore "softs."

What barrel make and action make do you have on your 404 Jeffery?
