| .45-70 Handi Rifle load?? | Login/Join |
| one of us |
I want to work up a level 2 load of ~1500-1600fps with the 500gr hornady RNSP for my NEF SB2 Handi Rifle. FWIW, Buffalo Bore offers a 500gr jacketed bullet cartridge with a MV of 1625fps, according to their website, which is suitable for use in a handi rifle. I'm aware of the recoil factor, it's not an issue for me, I just like big bullets. I've got a few recommendations so far, just wondering if anyone has any thoughts or experience to share. thanks http://www.buffalobore.com/ammunition/default.htm#4570 | ||

try 18 grains of Unique and a 300 grain hp. I think you will like it a lot more than a 500 grain bullet at 1625 fps. | |||

I have several loads for the "little" bullets that are moa accurate in the handi rifle, just want to try these big boys to see what can be done. I also have another motive for working up this load....got some friends interested in this load for a private bison hunt with their handi rifles so I'm gonna be the ginea pig!  | |||

Not after I finish with my mods! I have the laminated stock set for it with a limbsaver recoil pad and the stock screw opening filled with lead or lead shot. I have a past magnum recoil shoulder pad and can shoot from a standing bench. If that's not enough, then it's 350gn RN or 330grLHP......  I figure if I can handle my 835 ultimag with 3.5", 2.25 oz turkey loads, whats a little 500gr load gonna do! | |||

I think that this 500 grain bullet at 1625 fpa out of a handirifle is going to hurt a lot. it hurts even thinking about it | |||

Send me an EMAIL offline, and I'll run you the quickload for this, if you request those results, for INFORMATIONAL purposes only. IMHO, the handirifle is AT LEAST as strong as the whippy contender.... jeffe | |||

saying that the handirifle is as strong as a contender isn't necessarily a strong point. I have had a contender for close to 25 years and there are definitely some calibers that it shouldn't have been chambered in becuase of them opening up under recoil. A friend of mine shot some 420 grain(?) Buffalo Bore ammo in a Marlin guide gun and he didn't think that was a very smart move because ut really hurt. the 45-70 is a great cartdrige and really doesn't have to be loaded up very hot to be a good killer | |||

I have loaded 500 grains up too 1700 fps...its no fun in the handi rifle. The loads I tried where both with IMR-4064 Remington brass and Winchester primers first load was 50 grains for chrono 1563 fps 2nd load was 55 grains for chrono 1702 fps If you use these loads work up slow hope this helps Jason | |||

Jason, that 50gr load sounds about right, how was the accuracy? What specific bullet were you using and what was the COAL? Thanks, Tim | |||

Wow, 2.90"!! I was thinking the handi .45-70 had a short throat from what I had read, that's good news, thanks! I hear ya on the recoil, I suspect I might change my mind about the big bullets even with all my "precautions". I have a box of 350 RN that are my go-to bullets if this doesn't work out, but I need to try, anyway.  ..thanks | |||

Wrongtarget 2.90 was the COL. with Hornady 500 grains SP. I didnt really shoot them for accuracy. Just put the target out to about 25 yards so that I could shoot over the chrono. After shooting 5 of each..the 50 grain and the 55 grain. I really didnt feel like shooting off a bench @ 100 yards. My shoulder was hurt enough. When it gets cooler here in Arizona I will let you know. that means I will be shooting with a Jacket on. less pain. | |||

Wow, pretty impressive! Holding the rifle in your hands is a good way to keep the auto ejected brass from making a forehead score!! Thanks, Clark!! | |||

Here is my test data for my 45/70 Handi rifle with 405 gr hard cast and Unique: 45/70 work up with; 405 gr cast with lube bands, CCI 200 primers, Win brass, old Unique [dirty] powder, chamber well lubricated between firings with CLP for max bolt thrust.

Reference loads: 1) "Loads for the 45/70" from the H.P.White laboratory via "American Rifleman" 1950~1968 via "NRA Handloader's Guide" 1969 says: 405 gr Rem S.P., 17.5 gr Unique, 1286 fps, 25,240 pounds pressure, for 1886 Win 2) "Lyman's 47th" 1992 says: 400 gr cast, 16.5 gr Unique, 1286 fps, 27,000 cup, for 1886 Win 3) "Lyman's 47th" 1992 says: 385 cast gr cast, 17.5 gr Unique, 1411 fps, 38,500 cup, for Ruger #1 Here is a picture of what the primers looked like from right to left. Picture of the brass, shot 0), shot 8), shot 7)... And no it was not against my shoulder, or it would have broken my collar bone. It was in my hands. My left hand was on the butt and my right on the trigger. I absorbed the recoil over a stopping distance of 3 feet. The peak force on my left palm was very low. The reason I knew that it would be ok was the stress analysis I did. It is made of thick steel. Even assuming a low yield steel, it is still much stronger than a 454 Ruger revolver, which is made from the best steel. | |||

Steveno, your apprehension about expansion of the big 500gr bullet was right on, got this reply from hornady concerning my goal of 1500-1600fps mv. Guess I won't be working this load up. Thanks Quote: | |||
