.45/70 405gr. Load

[2-.36 1861 NAVYCOLTS]

GOING FOR ELK IN NEW MEXICO 1ST. WEEK OF OCTOBER. WOULD LIKE TO BRING MY RUGER #1..45/70 AS A BACK UP RIFLE (YOU NEVER KNOW). LOOKING FOR A LOAD FOR IT USING .405 GR. FNJSP. HAS ANYONE HAVE ANY GOOD LOADS FOR ME?
PS. MY MAIN RIFLE IS A .35 WHELEN BUILT ON A '98 MAUSER ACTION WITH A 24" SHILEN BARREL, USING HAND LOADS OF, 51.GRS OF IMR4320, REM. 91/2M PRIMERS, AND NOSELER 250GR. PARTITION HEADS.

I can't think of a better source of loading data than my friend and fellow writer John Taffin. John is a lever-gun fanatic, and has developed pet loads for almost any caliber that's ever been chambered in a lever action.

Here's a LINK (http://www.sixguns.com/) to his site.

I've been using the same 45 70 load for years with a 405
hollow point
55.6 grains of IMR 3031.
I'm shooting it though a NEF handi rifle. It groups real nice.
Muzzle velocity of about 2000 fps.
Big medicine on deer and black bear.

The remmington 405 grain bulk jacketed bullets shoot <1 MOA atop of 49 grain IMR 4198. Very heavy recoil, but excellent accuracy :)

I have been loading a hot 400-grain load for my No. 1 for years using the Barnes Original semispitzer and RE7 for a MV of 2270 FPS.

This load is accurate, but the recoil is so heavy I have to loop my left forefinger over the barrel to keep the rifle from jumping off the sandbag when I shoot it from the bench. However, I suspect this would make a helluv an elk killer! This load was worked up starting at 58 grains of RE7, and is based on RUGER NO. 1 load data from the 3rd Edition Hornady Manual. Rugers will stand up to such loads, Browning S.S.'s and Siamese Mausers MAY!! NO OTHERS!! I suspect this develops in the neighborhood of 50,000 PSI! It also shoots as flat as a 170-grain .30/30 load.

My all-time favorite .45/70 load is the Elmer Keith 1886 Winchester load, of a 400 -405 grain bullet and 53 grains of IMR 3031. Plenty powerful enough, and safe in most lever actions.

I shoot a Gibbs bolt rifle in .45-70. Those Enfield actions can handle a fairly heavy load. However, I wouldn't go much higher than 54 grains of IMR 3031. I tried 55 grains but the pressure signs were such that I don't think going there would be very wise. But suit yourself. The Ruger is a very strong action and it's quite possible that it can take all that and more. Just be very careful working up loads for it. Remember that a face full of steel from a blow-up isn't very pretty.

BTW. I just put a sportered Remington '03 in to be rebarreled. The chambering is to be .35 Whelen. I think that it's a fine choice for your primary arm. Elmer Keith was right, bigger is better.

Chet :D

Most of our readers are already in the know, but let me add this for anyone who needs it...

There are MANY different guns chambered for the century-old 45-70 cartridge, and some of them are significantly weaker than others. All loading manuals carry at LEAST three different levels of loads for the 45-70, divided by specific gun models.

Using the wrong data for the gun is EXTREMELY dangerous. Use data ONLY after double-checking it with a current manual, and then triple-check that it is appropriate for the model gun you are using.

Adirondacks...I;m betting your 55.6 load is a real thumper from a handi. When using 3031 under a 405 i used 46 grains ( 1500 fps ) 55.6 is about 2.5 grs over max , for level 2 rifles like the handi.

Kentlocks....49 grs of IMR 4198 under a 405 jacketed ? sure ? This is 5 - 6 grains over max for level 2 rifles. May i ask what you are using this load in ? I use 36.0 gr. ( 1500 fps )
