Home Forums Hunting & Shooting Express Rifles and Big Bores Only Need Cast Bullet Load Recipes for .416 Rem. Mag.

I need load recipes for .416 Remington Magnum with cast bullets. I want to work up some loads with bullets with wide flat metplates for hunting whitetails and hogs at ranges up to 100 yards or so. I've currently ordered some 350gr bullets out of RCBS mould RCBS 416-350-FN.

Please recommend loads for both this bullet and any others that you think might suit my purposes better.

I currently have a pound of 5744 and want data using that. But also Data with other powders that you've had better luck.

I hate weighing charges, so if 2 powders give equal results, but one of them meters better, please note that.

Please note whether standard or magnum primer and whether you recommend filler with your load.

I shoot a lot of cast 375 grain .416 bullets with surplus IMR 7383 powder from Jeff Bartlett. Good thread on cast bullets 416 rem loads at www.shootersforum.com Definitely need Fed 215 primers to ignite the IMR 7383 but no filler required. Absolutely get a cast bullet neck expanding die so as to not shave lead when bullet seating. Seating depth should not allow bullet base below case neck junction.

I use 50 grains 5744 with a magnum primer in my .416 Rigby. No leading seen and the accuracy is fine for 100 yds. IMR 4198 was slightly more accurate with leftover Rem 9 1/2 M primers. However, in hot weather I had delayed ignition so I stick with 5744 -- 1900 fps or so, FWIW.

Western Bullets worked fine but I have friend pouring linotype boolits using a mould I bought from someone he recommended. They come out lighter than 350-grains and I had to size them to .416 for easy feeding. (Had to do nothing extra with WB.)

I finally broke down and ordered the Lyman Cast Bullet Handbook. It had just what I am looking for.

350gr cast bullet, 5744 powder.

Starting load: 37.5gr for 1708 fps
Max load: 50.5gr for 2175 fps

Since I only want about 1850 fps, I'll probably start at 37.5gr and stop when I get to 41.5gr
