I have just put together some loads for the .416 Rigby. I used the data I found on the Alliant website. They suggested that 96 grains of Reloder 22 would drive a 400 grain Hornaday at 2355 fps. That seems a bit optimistic to me. Has anyone done any chronographing with their .416 Rigby using RL22?

I get 2430 fps. with 100 gr. RL 15,400 gr. TSX and Fed 215's in my Ruger RSM. Geronimo | |||

In the past, I loaded 101 gr RL 22 for a velocity = 2450 sd 6.9 using the old 400 grain Barnes X bullet in a Ruger 416 Rigby. I did a lot of shooting with reloads using IMR 4831 (had a bunch then) and 96 grains IMR 4831 produced a velocity = 2463 sd= 8.9 with the 400 grain X bullet. Would of course start lower. | |||

Dave Bush, I've chronographed that load and do get 2350 fps with the 400 TSX and A-Frame. 100 grains of RL22 and a 350 Speer gets 2450 fps. Both shoot considerably better than a .416 Rigby needs to in my rifle. | |||

Thanks to all and special thanks to Dogleg. I have some loaded up but my gun is still at the shop so that my gun guy can bed if for me. We did some chronographing last night with a 9,3X62 and a .404 Jeffery. As soon as I get the .416 I will run out to the range and shoot it across the chronograph as well. Thanks again!

I recently chronographed my 416 rigby; Jamison brass, 215 primers H4831 102 gr 400 gr hornADY solid 2360 fps (and, not that its important, sub minute of angle accuracy) IMR 4350 95gr barnes X 350 gr 2386 fps, very mild recoil (for a 416, excellent accuracy, bullets impact within 3" of Hornady 400 gr solid load H4831 108gr barnes X 300 gr 2510 fps, decent accuracy. Still working on faster 300 gr loads to see if I can make this a all in one plains game/DGR. If any ideas on loads, please let me know! Ive just (finally) figured out how to post pics, so here goes: from bottom, 416 Rigby by Blomfontein Custom rifles, %)% Gibbs by Fred Wells, 414 jeffreys by Brockman Custom rifles.

Well, I was finally able to get out to the range today and chronograph the load that I got off the Alliant Powder website. As I suspected, the Alliant data is a bit optimistic. The rifle was a CZ .416 Rigby with a 25 inch barrel. My load was a Hornaday case, Federal 215 magnum primer, 96 grains of Reloder 22 and a 400 grain Hornaday roundnose soft. The Alliant site shows a velocity of 2355 fps. In my rifle that load was only running about 2295 fps. It was a pussycat to shoot though. I think if I bump it up a couple of grains that should put me around 2350-2370 fps with a soft and that should be just about perfect.

Load 106 grains with a 400 grain bullet, this will go just under 2700 and will not be a pussycat to shoot either. Actually all you need to know about loading .416 Rigby ammo is H4831 105 grains. This will run about 2500 and works in almost any of them and has for years. A shot not taken is always a miss | |||

jstevens, I just don't see any need to load the Rigby that hot. I am a big believer in the original ballistics for these great old cartridges. The Rigby was originally loaded to about 2350 fps and performance was superb! Today, Kynoch only loads it to about 2300 fps. I plan on hunting with 410 grain Woodleighs and the velocity window for those bullets is 1900-2400 fps so 2350 at the muzzle is plenty fast enough. IMHO, if you crank the Rigby up to Weatherby velocities, you are just adding unnecessary recoil and putting too much stress on your bullets.

jstevens, You got it mostly right.  105-grains of H4831 in a .416 Rigby is the "Jack O'Connor Memorial" load. It is what JOC used. It gives about 2450 fps with 400-grainers, about 2500 fps with 380-grainers. Always accurate. Never a problem except for those who have Recoil Sensitivity Disorder (RSD). I used it on cape buffalo. Maybe if you tone the claimed velocity down to 2450-to-2500 fps with 410-to-380-grain bullets, it will not aggravate the RSD afflicted psyches. | |||

Just from a different perspective, had great luck with IMR-4350. 90.2gr of the stuff, Norma brass and Fed 215M primers. Right at 2400 fps with just about any 400gr bullet and 1/2" accuracy out of my old style Ruger RSM 416 Rigby. I settled on 400gr Swift A Frames and old fashioned Hornady 410gr Hornady solids. Great results on buffalo. jorge USN (ret) DRSS Verney-Carron 450NE Cogswell & Harrison 375 Fl NE Sabatti Big Five 375 FL Magnum NE DSC Life Member NRA Life Member | |||

Right. But the original 2,350 fps was in a 28" barrel. That original Kynoch load did about 2,250 in the 24" barrels that were used in the field.
...which is the original load in a 26" barrel instead of 28". At 2,295 fps in a 25" barrel, you're right on original ballistics, or just a touch hot. --------------------------------------------- "Serious rifles have two barrels, everything else just burns gunpowder." | |||

RIP I load 370 NF bullets with 105 H4831SC, goes 2550 in mine. Load them up to 2700 with RL22, but the recoil seems to double, probably not kill any better. A shot not taken is always a miss | |||

It seems like everyone is focussed on the 400gn bullets. What about using 450gn bullets. Woodleigh make a 450gn rated at 2200fps. Norma offers these at 2100fps in their PH range of factory ammo. I was under the impression that heavy for caliber bullets work best on large dangerous game. I would be interested to see what those with experience say. | |||

And I'm trying to come up with a good load for the 350 gr speer using H4350. I read somewhere that up to 102 gr was safe but my primers are starting to "crater" around the firing pin dimple at 101.5 gr. Group size is approx. the same from 94-101.5 gr in 2.5 gr increments. I dont think I'm going to be able to determine much till my scope and rings come in. I follow Rule #62. | |||
