varget, rRE7,IMR 4198 45/70
« on: March 19, 2009, 04:11:52 PM »
When my brass arrives I will be loading remington 300 gr bullets in starline brass in my NEF Buffalo Classic, I heard somewhere 4198 is not the best powder for a 32 inch barrel, does anyone know the most accurate powder for jacketed bullets in the BC rifle?

My BC has very shallow grooves and I haven't good luck at all with jacketed bullets.  I believe the shallow grooves are better suited for cast bullets.  (anyone more knowledgable on this, please feel free to correct me if I'm wrong)

5/25/09 update:
Don't know why I got that mixed up?  Yes, shallow grooves favor jacketed bullets.  I just had bad luck with jacketed bullets due to the loads I was working with at the time of the posting.  Sorry if I steered anyone wrong here.

I do admit however, I am still working on some loads for my 45-70 BC....haven't dialed it in completely yet AND the two powders I've chosen to work with thus far are IMR 4198 and IMR 3031.  Got decent results with both powders on the 410 grain and 500 grain cast bullets but pretty lousy results with 300 grain jacketed bullets. 
....still working on it yet...

There is a recent thread on 350 grain Hornaday bullets using 2400 that got what I thought to be pretty darn good results.  You might try looking for it....I can't seem to find it right off.

Thats odd, I wanted to shoot cast bullets but was afraid I would not be able to get an inch groups at 100 yards because of the shallow rifling, thats why I ordered jacketed bullets, I really wanted to try laser cast bullets.

Most CB shooters and the CBA believe just the opposite, that shallow grooves are best suited for jacketed bullets.  The hard jackets a gripped better by the shallow rifling and are less likely to slip and strip, particularly with hotter loads.

My .45-70 Trapper - the predecessor of the BC - shoots very well with 300-grain jacketed bullets and 40-45 grains of IMR4198.  It shoots almost as well with the 350 Hornadys and 5 grains less powder.  The only cast bullets it shoots well are the RCBS 405 with gaschecks and 26 grains of IMR4227.

I've used IMR4064 for 300JHP and Speer 400JSP with great results in my BC 45-70.

I've had good luck in my Buffalo Classic with Cast Performance 405 gr gas check bullets and Varget powder.
The powder charge put it in the Marlin load levels, so it's not exactly easy on recoil, but the accuracy is there. 
I haven't handloaded any jacketed bullets, but the gun seemed to like Remington 405 gr factory ammo.
I can't say anything on 300 gr ammo.  I don't think the gun has ever had that weight bullet through the barrel.

Don't over look IMR3031 for your .45-70 I have found it to be my best choice in the old round for both cast and jacket bullet use. It always gave me excellent accuracy and the velocity I wanted tho admittedly I never looked for maximum velocity as some do from it.

I like Varget.  The 405 grain Remington bullet shoots great in my Handis.

Like Swampy I have found Varget to be a good powder for the 405gr Rem bullet. I use 50gr of it in my Marlin and the accuracy and recoil are more than acceptable.

Here's the link for the load using 2400 that I had referred to:

MSP Ret's 45/70 load
http://www.gboreloaded.com/forums/index.php/topic,167006.0.html

The load seems to be a little on the lighter side but if you're not looking for max loads, it looks promising.  I still haven't had a chance to do any jacketed bullet loading for my BC yet but thus far I've had some pretty good luck with IMR 4198 and 2400 under 500 grain cast bullets.

Like a couple of others, I have settled on Varget.  I shoot two different bullet / load combos.  I have a 330 gr. hollow point mold, and I use a mid range load of Varget in that.  With my 405 gr. hollow base mold, I use 40 gr. Varget for a very light recoil, and very accurate load.  The 405 is my most accurate so far, and on a day when I can do my part, I can get < 1" groups.  I have not gotten as good accuracy with jacketed bullets at all, but it is still most acceptable for hunting.  With some 500 gr. semi jacket flat points, I can get 2" groups at 100.  If I worked with it, it might tighten up, and I may try it more later.

Looking at the MV's that atLaw got out of the 28 gr loads it appears they are almost 400 fps lower then Hornady recommends as a minimum V for the 350 gr RN's

I believe those Hornady 350's are made with the various .458 Mags in mind, not 45/70's.  If I can ever get to the range I'll shoot those loads we taked about before.

I'm not sure that the 350's were ever designed for the 458mags, but who knows. I can tell you that I shot the 350FP bullet @ 1,900 in my 45-70 and got good expansion on a Maine black bear. I would imagine that the RN version would expand about the same.

The 350 RN were designed for the458 Mag. The FN's came out much later and at 1900 fps they are above the minimum so they worked out OK for you as they should have.
