Ranch Rog TLC460-425-RF Powder H-322?

[JesterGrin_1]

Anyone know of a good load for this round in the Marlin 1895GS 45-70 with H-322 powder? Ranch Dog Michael gives a starting load of 44.0Gr to a max of 46.5Gr but has not had much time for testing of this round so I thought I would ask this question here of all of the Lead Heads. :)

Bump for HELP :)

H322 is a very good powder in the 45-70. While I'm not totally familiar with Ranchdog's 425 grain boolit, I have used H322 and a bunch of different 420 grain boolits. Beartooth also has a 425 gr, Pile Driver Jr. He has some data lited on his load swap site. Every different 420-425 gr boolit has it's own unique bearing length. Alloy hardness, PB or GC, and nose configuration all come into play when dealing with pressure. I am actually a bit surprised at the max powder charge you list. It is several grains shy of the max I have for my 450 Marlin. Most top end 45-70 loadins would be 2-3 grains above that. I guess it would all depend on the case brand used for testing.

In the 45-70, Remington has the least case volume, Starline is in the middle, and Winchester holds the most. Starline nickle plated cases should be avoided. Capacity is a touch less than the standard ones and the higher hardness raises pressure considerably. Lever gun cartridges that operate in the 40k psi range are extremely difficult to judge as far as pressure. Primer condition, extraction difficulties, and case head expansion are not good indicators. Any of the normal signs will tell you one thing. You've already well exceeded pressure.

The best bet is to work from book data and use a chronograph. I have found that H322, combined with the Federal 210M primer, is outstanding in the Guide Gun. Less than 1 inch groups are easily do-able. You should be able to get more information on Beartooth, MarlinOwners, and Levergunlovers forums as well. Alot of those folks shoot the 420 gr boolits from JB Young (Crater Lite), and Cast Performance.

Thank you for the info BABore. But I did search for awhile and did not find anything for the H-322 powder. Well I did find one but the load of which it gave seemed way out there lol. I think it mentioned 50.0Gr of H-322 with the 425Gr Pile Driver Jr.

And Yes I use the Fed 210 primer now but due to lack of getting primers I may go to the Wolf Large Rifle Primer. And I use Remington case.

The Ranch Dog shows that for the 425Gr there is .645 inside of the case. But I could not find this info for the Pile Driver Jr in 425Gr.? If they both reside inside of the case the same and take up the same space then we will have something. :)

If you find any info please let me know. :)

What level loads are you looking for? H-322 is great for full power heavy boolit loads, but might not be ideal for standard pressure stuff. The 50 gr. load may be a fine load. That is the charge my brother shoots with a 450 gr. in his Guide Gun. 1/2" 50 yd. groups, 1,800 fps.

Not very pleasant from the bench, but whacks stuff nicely. Just wondering how fast you were looking to drive a 425.

I use 50.0gr of H-322 with a 430gr paper patch in my 1895g when I feel the need for speed.

Currently I have been using 52.OGr of H-322 in my Marlin 1895GS with the Ranch Dog 350Gr which will shoot a good group of 1 inch or less at 100 yards if I do my part but I will have to say it thumps lol. The bottom two are sight in and the top three for group. It shoots a bit tighter than the Hornaday 350Gr RN with 53.OGr of H-322 but not by much.

I just purchased the RD 425Gr and did hope to find a good starting and stop point as far as how much powder will work with safety in a Remington 45-70 case? I am not a person that looks for speed as I like to start from the lowest powder setting and work up from there to find an accurate load. As what I think is that with a 425Gr BOOLIT hitting something alive that it would not notice a couple of hundred feet per second difference lol.

As measured by Brian Pierce!!!

1-.450 Marlin Brass/73.5 grains of water(2.7 grains less than Remington 45-70Brass!!!)
2-.45-70 Remington Brass/76.2 grains of water(1.3 grains less than Starline Brass)
3-.45-70 Starline Brass/77.5 grains of water(2.8 grains less than Winchester Brass)
4-.45-70 Winchester Brass/80.3 grains of water.(4.1 grains "More" than Remington Brass.)

Using Remington cases, I would not exceed 50 grains of H322. I would start out at 45 grains and work up. Your more than likely to find your accuracy at 48-49 grains.

Your RD 460-350 GC load peaked about the same level as in my 450 Marlin, correcting for case capacity differences. I was at 48.0 grains with the same accuracy level. The same weight jacketed bullet had a max charge that was 10 grains hotter.

I use 425grn bear tooth bollit with 53grn of h322 in my guide gun.

bwarren86 Welcome to the forum. You sure did bring up an old thread lol.

But I will update it. For my Ranch Dog 460-425Gr RNFP/GC the best load I found is 45.OGr of H-322 in Rem Brass with the Fed 210 Primer. I did not get as good of a group with the 425 as I do the 350Gr. And thus far I have chose not to use the 425 Gr due to the extra drop I would have to work around with the 425 Gr.

The Bear Tooth 425 and the Ranch Dog 425 is not the same. The Bear Tooth takes up less case space than the Ranch Dog. Thus you can use more powder for the Bear Tooth but it will thump on both ends lol.
