Well finally after much frustration with actions I am underway. Kevin with Weaver Rifles is building a 416 Rigby on a Stuart Satterlee action and Pacnor blb. I picked out a piece of wood from Jim Biseo. I will be off to Moz for buff/leopard in late June. This makes for a short time of developing a load for 400 solid and something for the first shot. Any advise on your best loads??  | ||

huntnjim Congradulation on you're Rigby, I also ordered a 416 Rigby, should be here Wendsday. If you go to favorite loads and do a search you might find some good starting loads. Good-Luck on you're buff/leopard hunt, let us know how it went.  Steve | |||

Put ONE HUNDRED GRAINS of VihtaVuori N165 in a Norma case with a Federal 215M primer, seat a 400 grain bullet on top it. I just love the 100 grain number, even I can remember what my load is. With Rhino Solid Shanks I get an average of 2390 fps at 50 degrees Fahrenheit ambient temperature. With Barnes bullets you get a little faster velocity. The Northfork bullets are excellent. You might want to work up some dummy bullets with the Northfork flat point solids (fps) and the cup point solids (cps) and give them to your smith so that he can assure that they feed well in your rifle before you take delivery. In my factory CZ 550 the cup point solids don't feed reliably but I don't know a smith in France that I would trust to "fix" it for me. I'm not saying they don't exist, I'm just wary, sticking to A-Frame and Rhino for the expansive bullets and Barnes Banded Solids for the solid. All three will feed in just about any rifle. _________________________________ AR, where the hopeless, hysterical hypochondriacs of history become the nattering nabobs of negativisim. | |||

huntnjim, you don't have much time to get a rifle built. Make sure you have a back-up plan. Do you have the action in hand already? ______________________________ "Truth is the daughter of time." Francis Bacon | |||

Wink simple #s (100 g) are nice and easy to remember however I did write it down and will try your load. I was looking for near 2400 fps with the 400 depending on the type of recoil. ForestB, Stuart will have the action within this month and Kevin will jump right on it. The other action I ordered was not the quality we were looking for and we were delayed by several months receiving it. Stuart is a (real standup) guy and knows we are under time constraints building this one. Kevin (owner of Weaver Rifles)is also one of the best and most honest builders.The A Team is on it and I trust it will be complete with a minimum of six weeks to get to know the rifle and find loads that shoot well. I will take all the help from you guys on loads that you can recommend. BTW the Pacnor barrel will be 24". | |||

90.2gr IMR 4350. Fed 215M primers, Norma cases 400gr Swift A Frames or Hornady solids (steel). Same POI @ 2400 fps. Worked great 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 | |||

Jack O'Connor load was 105.0 grains of H4831 with 400 to 410 grain bullets. I reckon he was using old surplus powder, so the modern stuff differs, etc., so start 10% low and work up, as usual. But I have never had a max load, and 105 grains is as high as I have gone. I have used that solitary, unchanginging, immutable powder charge weight with 380 to 400 grain bullets. Either Long cut H4831, or the H4831SC which is easier to meter. Norma case. GM215M primer. I tell you it is magic. It makes the 380 grain GSC FN go just over 2500 fps from a 24" barrel (2509 fps). This load puts 3 shots into 0.179" center-to-center at 100 yards. Any 400 grain bullet I tried with it (many) was sub-MOA and just under 2500 fps. That same magical powder charge should work fine with the 370-grain North Fork SS, FP and CP, though the grooved softs will produce higher presures than the banded bullets. The .416 Rigby needs a full case of relatively slow powder to work best with the heavier bullets, IMHO. I use around 100 grains of the 4350's with 350 and 330 grain bullets at 2700 and 2800 fps, respectively. None of these that I have tried are high pressure loads for my rifle. Of course rifles differ so start 10% low, yada, yada ... The Jack O'Connor powder charge did this in Botswana in 2001, with the .416/380-grain GSC FN: 1-shot (after fly-in) sighter, before buffalo hunt: dead on at 100 yards, PH is my witness. 1-shot at live buffalo: killed buffalo 1-shot at dead buffalo: as directed by PH PH Ronnie McFarlane appreciated GSC FN solid quality and its ease on his rifle bore. He wanted my ammo for his original Rigby .416 Rigby, and I left it with him for use on buffalo and elephant (GSC FN solids). | |||

Jim, Good for you. I hope this means my Satterlee action will be finished this month too. I posted a bunch of my 416 Rigby test loads awhile back.

RIP, With 105 grains is this a compressed load with your seating? | |||

ForrestB, Good info with the link! Thanks man! | |||

105 grains of H4831 is sure not a compressed load in the .416. I load that with the 370 North Fork and back it off a couple grains with solids for sight regulation. The 370 NF with 105 H4831SC chronos 2530 fps in my Ruger and shoots below 1MOA with a lot of 3-shot groups .5 or less. I don't shoot any 5-shot groups with the .416. The best group went .253, making a darn nice varmint rifle out of it with only a 1.76-6x scope. A shot not taken is always a miss | |||

I prefer 4831SC for the 416 Rigby, but I recently bought some surplus powder from gibrass.com, #860, which loads with AA8700 data... For the price, I couldn't pass it up, 8 pounds for $40! Has anyone tried the 860? Thanks! | |||

I had the same experience with this load. Every 400 grain bullet I tried would shoot less than .5 MOA with many groups resulting in one hole at 100 yards. Once I tried it, there was never a reason to try anything else. It does seem to be the magic combo for the 416 Rigby. Tim | |||

I use 102gr 4831SC behind any 400gr bullet, Norma brass, Fed 215 primer. Very accurate at about 2400, in fact I've never yet tried a 400gr bullet that wasn't MOA or less with this load. Have fun; Brett | |||
