Thinking about loading up some Oregon Trail 350gr RNFP.

Anyone have any published loads for this bullet weight and powder?

Not specifically (IIRC)

But I DO have a load for the Gould 320, which is 21gr for 1293fps or 28gr @ 1640fps.

max I show (ased on a Ruger #1 action) is 34.5 @ 1958 fps...

Alliant's cowboy load of 25.0 gr with a 400 gr bullet is a good start. They list 1250 fps but in my rifle it is faster.

[b]I HAVE USED 20/2400 WITH 350 GR JACKETED BULLETS AND 24 GRAINS WITH 340 GRAIN CAST BULLETS.... YOU CAN LOAD MUCH HEAVIER BUT FOR ACCURATE FUN LOADS WITH POWER AND LITTLE RECOIL THAT WILL TAKE BLACK BEAR AND DEER... THESE FIT ME... PACO

Check the Alliant web site, they have some silhouette loads using 2400 in rifles. Also Oregon Trail will send you load data upon request.

I put 25 grains ubder a 405 bullet all the time, its my regular 45/70 load. I got about 1250 with an 18.5" barrel but dont know what I get from my 22" now. From my gun its a nice acurate easy to shoot load.

Thanks everyone. I think I'll run 25gr to start and see where that gets me. Also, has anyone done up their 2400 loads using a large pistol primer. These should be pretty low pressure loads compared to my 44mag so I dont think itll be a problem. Is this correct, or is a large rifle necessary?

I'd use a large rifle primer. Its a messy powder as it is & I gotta think a pistol primer may make it worse. Could be wrong tho because I tried LRM primers & it got no better.

You should be aware too the large pistol primers are shorter than large rifle. Probably not enough to matter but that I cant say.

I would work up the load using a Magnum large rifle powder, 2400 likes lots of ignition. I always used a magnum primer when I used 2400 in pistol reloading.

Try this site www.gmdr.com click on Oregon Trail cowboy load data. www.realguns.com/loads/4570cast.htm 300gr OT bullets using 2400 28gr=1619fps & 30gr= 1709fps

Here is a vote for the large rifle primer. The smallest group with my Marlin 45-70s was with a Winchester WLR, 25.0 gr of 2400 and a Speer 400 for 7/16" at 100 yds for 3 shots. Other groups were also very good.

Large Rifle it is then.

I'm also thinking hard about that 400gr bullet and 25gr 2400.

It may not be a "magnum" type load, but I figure being able to use 2400 (a powder I have plenty of) for pushing such a big hunk of lead at a decent velocity, makes it just different enough from my 45colt/44mag loads (and more economical) to make reloading for it worth while. I'm certain my brass may last a few loads longer.

Thanks again for all thehelpful input.
