Two weeks ago I chrono'd some Federal Premium Safari 410gr Ammo in my Heym and got 2297fps equating to 4804.65 ft/lbs. Today I shot some handloads and the results are quite surprising, because I achieved a healthy velocity increase, even in my 24" barrel. I used Norma brass, Fed 215 primer, Hornady 400gr FMJ ENC Solids #41677 and Reloader 22 powder. Cartridge OAL was 3.615" and a moderate roll crimp into the cannelure was used. Here's the data :- 100gr RL22 - 2480fps 5462ft/lbs SD 28fps 102gr RL22 - 2515fps 5617ft/lbs SD 30fps 104gr RL22 - 2554fps 5793ft/lbs SD 32fps Those few hundred fps might not seem that much but you can definately feel it in recoil terms. Whether old Mbogo will know the difference, I doubt it. I'll probably settle on the 100gr RL22 load as it achieves my goal of an honest 2450fps. Hope other Rigby owners out there find this data useful  | ||

Thanks Spie, I will give that load a try. JCN | |||

Spie, Met a gentleman on Saturday who uses 112 grains of Rel 19 with the 400 grain bullets. Can only imagine his muzzle velocity. By the way, after shooting the relatively mild factory loads in the 416 Remington magnum, I had NO desire to try this guys 416 Rigby loads, as they noticeably shoved the shooters around more. With regard to whether or not a buffalo can "feel" the difference. I personally doubt it IF you are using solids. If you are using soft point the old buffalo most likely will notice the difference.

Hey Spie, I use that same load and it shoots well in my Ruger. However 100grs. of H-4831, Fed 215M primer gives almost the same velocities, recoil not quite as sharp, slightly better accuracy. Might want to give it a try. I've seen a bunch of posts on this, and other sites, by folks who think H-4831 is THE powder for the .416 Rigby. Kinda like H-4350 for the 30-06. As you can tell I'm starting to lean that way myself. | |||

Quote: Thanks for the tip. Are you using the SC version of H4831? Just had a quick look through my manuals/websites for an RL22/H4831 comparison (all loads are MAX with a 400gr bullet) and this is what I found :- Barnes - 104gr RL22 (2556fps), 104gr H4831 (2553fps) Nosler - 104gr RL22 (2515fps), 99gr H4831SC (2462fps) Speer - 101gr RL22 (2311fps), 104gr H4831SC (2372fps) In my rifle and with Hornady bullets, the Barnes data looks bang on. Speer say their load is compressed which is surprising as there is still room in my Norma Brass for more powder. Its funny how I've ended up using RL22 is all 3 of my hunting rifles - .243, 7mm Rem Mag and .416 Rigby. It just seems to work. | |||

I use H-4831 long cut in my Rigby because I like the bulk. My practice load is 98 grains of H-4831, Fed 215 M, Norma brass, and Hornady bullets. The iron sights are right on, and it is mellow to shoot. JCN | |||

WLRM Primers Norma Brass IMR 4831 400gr Barnes solids 96gr = 2515 fps / 5619fpe WLRM Primers Norma Brass IMR 4831 410gr Woodliegh RN SP 96gr = 2410 fps / 5290 fpe It seems to me you should try IMR. same velocity and energy with less powder. Shot in my CZ 550 American Safari Magnum .416 Rigby (25" barrel) I love that gun. Don | |||

Yeah, The IMR is one RCH< !--color--> faster than the Hodgdon. Here is a great ground squirrel and pooty tat load: Norma Brass, Federal 215M, 50 grains of Accurate XMP 5744, 350 grain RCBS GC FN from Western Bullets ($9.00/bag). Goes 2000fps. Easy shooting, nothing left but whiskers and toenails..... | |||

When I first started using that load I didn't know about the SC stuff. Once I tried the SC I liked it because it seems to meter better. Doesn't seem to be any change as far as accuracy or velocity. Geronimo | |||

My 416 Rigby is being built. It too will have a 25" barrel. My goal is to get as close as possible to John Rigby's original loads. I've bought 150 410 grn Woodleigh Weldcores. But no brass yet. "Next year" is what I get for answer. | |||

I have shot mine with as much as 106 gr RL22 at almost 2700 fps in mine. Recoil is substantially worse, and the extra velocity isn't needed. I like 104-105 grains of H4831SC with a 370 North Fork for 2550 fps and 3/4 in. groups are less. I agree with one of the other posters that recoil seems to be a lot less with these loads and 4831 rather than RL22. A shot not taken is always a miss | |||

Spie, With my Rem416 I shoot the 400 gr Hornady bullet at 2424 fps. I know what you mean about recoil above those FPS. So my FPS is fast enought for me. | |||

thanks for the data, all of you guys. I just acquired a CZ 416 Rigby a month or so back, and have been busy with the Gibbs thingie and developing loading data for a friend's 505 Gibbs. Rich | |||

Spie, My standard "go-to" load for a 400-410 gr bullet in the Rigby is 100 gr RL-22 for around 2400fps. Higher charges are fun but the recoil goes into the Lott category (which I reserve for my 458 Lott  ). My usual "screwing around" 416 Rigby load is a Hornady 400 over 100 gr RL-22, which dispatches ground squirrels with panache and gives gravel pit rocks nightmares.John There are those that do, those that dream, and those that only read about it and then post their "expertise" on AR! | |||
