starting down the 25-20 SS road

I am starting done the .25-20 SS road, new to me rifles and all.  One rifle is a not-traditional ruger #1 that just required a stock. I have one on hand that only requires minor fitting and some semi-finishing; the final finish can wait. And then there is a more tradtional #2 'roller project in the mills of Adrian.

I have one mold so far that I am awaiting, an old ideal 25720--88 gr if i remember the numbers right. I have been advised that I might do better with a longer heavier bullet.  I may create another thread discussing that topic.  I have cases tools etc etc either on hand or on order.

My current question is re powder. 
Some years ago when I was picking up bulk powder at that "pull-down" place in Owensboro KY for Jim Borton I picked up 2 8#jugs of a mil-surp 5.56 powder that was the "equivalent" of 335 for my own use in small case centerfire cartridges. 
Since I have plenty of it on hand  .  .  .  .  .   Wink
  Does anyone use 322 in the 25-20's?
  Any recommendations re: a starting charge?

No direct knowledge on the use of 335 in the 25-20. However, I've had good luck asking the powder mfgrs directly about the use of their powders in various cartridges. If 335 isn't in the loading manuals for the 25-20WCF (their loads are pretty much interchangeable) then write the powder mfgr and ask them to recommend a load with a particular weight bullet. They all have a contact e-mail or section on their websites. Don't give them anything exotic as a bullet as they will not have any info on same. You can do the same with Hornady and Sierra and ask for a recommended load of 335 with their heaviest 25cal bullet. Think they both make a jacketed bullet in the 120gr range. You will know that is the largest safe 'recommended' load in a modern rifle. Once they respond ask them about shooting a cast bullet at 1500fps. Their programs for loads are much more sophisticated then any of the Greenhill and other formulas we have access to. If you tell any of the folks you ask too much, like you are shooting an antique rifle, etc., they will tell you they have no info and get all lawyered up.

I also imagine that asking about the load in a 25-20 WR would make more sense that asking about it in the 25-20SS

Yes. The 25-20WCF is a standard cartridge even today. They will likely not know what you are talking about if you mention the 25-20SS.
