Norma brass or nickel plated Federal case
Federal GM215M primer
H4831 "Extreme" 104.0 grains
Any 400 grain bullet tried: They all shoot to the same point of impact.
The Swift 400 grain A-Frame was very accurate. I think Swift quality control has made sub MOA easy since I last tried them in the 1980's.
The Speer 400 grain AGS, also very accurate, did the most damage to the 3/4" thick steel plate gong. The tungsten penetrator alone poked through the back side of the plate, of the three solids I tried. The Hornady FMJ and the Barnes solids in 400 grain .416 also were accurate and did considerable steel excavation.
The Swift and Speer both did right at 2450 fps with this load and are my choice for a 400 grain soft and solid combo.
I would like to try the GS Custom 380 grain FN solid. I'll bet it works great with 104 grains of H4831 also, as does the 400 grain Barnes X-Bullet I have used in the past, 104 grains of H4831.
Another favorite past load is the 350 grain X-Bullet with IMR 4831, 101.0 grains, other componets the same. 2700 fps, sub MOA. Note the IMR 4831 used with the lighter bullet, versus the H4831 used with the 400 grain bullets.

I am not into reloading per se, just lookibg for something that works. I don't appreciate loading 16 different powders and bullet weights in the same rifle, just try to simplify hunting and shooting. To each his own.
It is amazing, though, that Barnes solids, Swift, Nosler, Hornady solids, and Speer AGS solids all shoot the same, the same point of impact to the best as I can tell (similar to the famous characteristics of the .375).
I wish I had done this Rigby thing a long time ago.

I too am a recent convert to the .416 Rigby. Of course George Hoffman's rationale in creating the .416 Hoffman is easily understood in light of scarcity of the Rigby back then.
The .416 comes closest to bridging the span from true hunting rifle to stopping rifle of any other caliber.

Excuse the flight of fancy, but I simply love this round. While 400 gr. bullets certainly have their place, there are other bullets that truly make the .416 Rigby a do anything, anywhere cartridge. My personal favorite load in my Ruger No. 1 and will certainly be tested in my soon coming M77 Magnum, is a 325 gr. X bullet over 110 gr. of IMR 4831 for a 2924.5 fps velocity. Further yielding 3/4" 5 shot groups at 100 yards, and 1.25" groups at 200 yards. If the new 77 shoots as well as the No.1, then I will be a happy camper.
I cannot count the number of safaris I've been on with this round by simply holding it in my hand, and letting the imagination do the rest.
Amen.
Thanks for the post. My master plan for rifle building includes the .416 Hoffman, because it will handle any of the long H&H based ammo in a pinch. Got any more of your books left?
