Varget is one of those powders I've never seen in my area. With the way things are at the moment I'm glad I at least saw it coming and got what I did. :D

Now Doc sent me this in regards to my question to him, listing the 3 powders I had. I guess he thought I was talking about a Marlin with the 40,000 CUP comment but was looking for a starting place really.
First off Joe, If you can shoot them at 40,000 CUP.... you are a better man then me!! OMG that would hurt!! I like IMR-3031 out of those since it is one of my favorite powders for these boolits. My starting load for the 430gr is 41gr (cant remember the fps on that one though) 42gr is around mid 1500fps
starting load for the 535gr would be around 38 or so (i shoot mine at 41) so start low and work your way up and look for the groups.

Doc
As with everything else Varget has gotten pretty rare around here too. It is top of my list if and when I find it.
Rio Grand .45-70
Many more guns, reloading equipment, etc etc.

I pretty much have the IMR 3031 nailed down but still looking for IMR 4198 and Reloader 7 loads behind the 430 gr and 535 gr bullets. I got them today as sized them for my RG and made up a dummy of each to test for cycling which it did fine. It seems everybody has the 3031 load down for the 430 gr but still little on the 535. I did get a few H4198 however it is a bit different than the IMR 4198 but if I use the lowest it might work up from there.

What are the bullet lengths and diameters plus the cartridge overall lengths and I will run them for you. I will also need to know what pressure you want to push them to.

Ok I hope I do this correct. The OAL for both are 2.50 which cycle fine in my Rossi. Both bullet diameters as sized at .458.

430 gr Gas Checked is total bullet length is 1.035 from to gas check. The 535 gr with gas check 1.285 also gas check to nose of bullet. Brass is length is standard sized with Lee sizing set up. All brass is Starline with CCI large rifle primers. As for pressure I'm looking for something safe as close to the top of a Rio Grande 45-70 and then will reduce that down 10% to start and work up to it for accuracy. At least that is what I'm figuring at this point as I figure these babies will kill almost anything in this hemisphere with any of those 3 powders.

Much appreciated Ranch Dog for the assistance.

Here you go Joe:

45-70 Govt for the RG4570 at an OAL of 2.500". I think the RG is fully capable of 35.0 KPSI so that is what these loads are generated to. I generate loads with a case capacity of 86% to 105%, that has worked best all around for me. From my work with the pressure trace equipment and at the reloading bench, loads exceeding 105% have issues. The only powder affected by this caveat is IMR 3031 but you will see that I've included a 35.0 KPSI load with it for comparison. Finally, with RLD 7 there is always the question of; "are you talking about the new or old formula". The answer is; "I don't know", so use all the information below at your own risk.

430-grain lead bullet that is 1.035" long and sized to .458":
IMR 3031, 47.6-grains, 1698 FPS, 105% Case Capacity, 29.1 KPSI
IMR 3031, 50.3-grains, 1805 FPS, 111% Case Capacity, 35.0 KPSI
IMR 4198, 41.2-grains, 1730 FPS, 95% Case Capacity, 35.0 KPSI
RLD 7, 42.6-grains, 1733 FPS, 91% Case Capacity, 35.0 KPSI

535-grain lead bullet that is 1.285" long and sized to .458":
IMR 3031, 38.2-grains, 1428 FPS, 105% Case Capacity, 28.3 KPSI
IMR 3031, 40.8-grains, 1533 FPS, 112% Case Capacity, 35.0 KPSI
IMR 4198, 33.4-grains, 1461 FPS, 96% Case Capacity, 35.0 KPSI
RLD 7, 34.5-grains, 1465 FPS, 92% Case Capacity, 35.0 KPSI

The information has been calculated at 70°. When shooting your loads, consider the grain or velocity max. Do not exceed either.

The Reloader 7 was produced on Dec 15, 2009 based on the date on the side of it. Thank you Ranch Dog this is great. So now I reduce by 10% and start development from there.

Yes I kind of figured it would kill a jack rabbit. :D

I kind of had doubts it would load but cycled fine and set it to the crimp ring on the bullet.

I may have to order some of those 535's. I'd love to do some tests comparing those with my 525 Beartooths into 20" of spruce tree! Would like to recover some of each and see what sort of shape they are in which could say a lot about if Tombstone has a good bullet thats hard but not too brittle. I've been ordering from Beartooth and am very satisfied with them except it takes a long time to get them whereas my Tombstone 350gr order was here pronto..
No such thing as bad weather in Alaska, just lousy clothing choices!
