I tried some reduced loads in my RSM with IMR Trail Boss powder. Worked well. I called their tech folks for loading data and was told to do the following: Lay a case on your bench and then lay your bullet next to it aligned to the depth you want to seat your bullet. Mark the case at the base of the bullet then fill the case to that mark with trail boss. Weigh the charge, then take 70% of that number to determine a starting load. I'm loading the 400 Gr. Hornady Interlock for practice so I aligned the case mouth with the middle of the cannelure, marked and filled the case to that line. The powder charge weighed 37 grains. 37x70%= 25.9 Grains which I rounded off to 26 grains and loaded some test rounds. The rounds worked fine and the load was easy on the shoulder. Great for practice and plinking. I did notice that the point of impact was approx. 1" lower at 25 yds then my full power loads. I'm practicing at that range for my upcoming elephant hunt. Just thought I'd pass on the information in case anyone is looking for an easy reduced load for their 416 Rigby. Tom Z NRA Life Member | ||

Tom, I took my last elephant with a 416 Rigby...one shot, never even quivered. The Rigby is plenty of gun for the job. Good luck. | |||

try going to a lighter bullet with your Trail Boss noticed that Midway carries Speer hot core in 350gr might change your POI and they are very affordable | |||

Thanks Tom. Did you use filler/wad to take-up the remaining 30% free-space?

I am having great results with Trailboss and a 335gr LFN gas check from beartooth bullets in my 416 B&M. Will be using it in 416 RM as soon as I get dies. | |||

This thread presents some interesting questions. First question is what are you reducing your loads from? The original Rigby rounds were loaded with a 410 grain bullet at 2300 fps out of a 26 inch proof barrel. Most of the Rigbys had a 24 inch barrel so they made their reputation at about 2260 fps. At that velocity, the old Rigby killed everything that walked or crawled in Africa and should be quite manageable. Now, it is really easy to load the Rigby much, much faster. Most of my Rigby loads have been with a 350 grain TSX nudging 2600 fps out of a 24 inch barrel. My close friend is a Rigby guy and I think he loads his 410 bullets to 2550. Even though his gun is somewhat heavy, the recoil really gets your attention. I know that Tanz is going to jump in here cause he also uses the 350 TSX and I think his loads nudge 2800 fps. The faster loads allow you to shoot further and allow you to use your Rigby as a plains game gun as well. However, the traditional Rigby loads have and will kill most anything and there is a lot to be said for tradition. If you want a reduced load, why not just shoot your 410 Woodleighs (or a 400 grain Hornady for parctice) at 2260 fps?

No fillers or wads, just Trail Boss and a bullet. Trail Boss is a very bulky powder. It comes in 9 oz. containers which are the same size as the normal 16 oz. cans of powder. Dave Bush - I loaded these up just so I could practice more with my rifle without all the recoil of full power loads. I normally shoot some of the reduced loads first then finish up my practice session with a few full power loads with the 400 Gr. Hornadys. This is strickly short range practice for an upcoming elephant hunt. Tom Z NRA Life Member | |||

Have a Ruger MK II in .416 Rigby. Settled on 44 grains of 5744 with Hornady 400 grain bullets. Recoil is mild. With this I can get sub 0.5 MOA groups. Chronographed at 1720 fps. | |||

We did load down a few 350 TSX last year to 2400 fps in case my wife wanted to use the 416 Rigby. But the hunt needed to be shortened and the loads were shooting about 4" lower than the 2800 fps loads. Maybe next year? Those particular loads do not swap easily in the particular 25" rifle. My son did shoot a guinea fowl, aiming at the head and letting the bullet drop into the grain pouch. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

I am not much on reduced loads in big bores but I do wish Nosler would come out with a 350 grain Accubond. Talk about versatile. I could see me shooting it more. Push it out at about 2600+, whew. I just took mine to Argentina and used it on a big water buffalo with the Hornady factory solids. | |||

I uas Trail boss and cast projectiles in my Rigby for practice. Means I can run the rifle cheaply for some practice. | |||

I do the very same thing for the very same reason. About to start doing the same thing with my .458 Win Mag also. Just need to find some more Trail Boss. If ignorance is bliss; there are some blissful sonofaguns around here. We know who you are, so no reason to point yourselves out. | |||
