Before you give up on that 25-25, look in some of the older reloading manuals if you have them, I'm sure you can find some info on line concerning the caliber. The 25-25 was always a bit too long and a tad finicky with loading. as far as a cast action? So what. Its really not a hood ornament its a cast steel action plenty capable of the pressure of that round. The real weakness in Ballard rifles is not so much in the steel, but in the design. What everyone seems to be concerned with is the chamber pressure with these guns and having owned over 40 of them, I can tell you the real issue is going to be rearward thrust. Thats not to say I would load the behezues out of it or re barrel it into a 32 H&R magnum but use some common sense. If you found this forum you most likely possess some. It seems to me that I had some success with the round using duplex loads,( in a Stevens 44 action, which is fairly weak) I have used duplex in my Rigby before with mixed results so take that for what it is. You can get into trouble with duplex with the before mentioned rearward thrust so if you do not know how to make a duplex load, don't. Try some unique with it and see what type of accuracy you get,or trail boss, you never know. I don't think I need to say this but just in case, don't use jacketed bullets with any load in this gun. I, like Marlinman93, have never gotten the accuracy Ned Roberts did with the round but perhaps you can. If not then at least you can always go to a .32 ideal or .22 rim fire or have the barrel turned down and chambered into a 25-21. But I would try it out first. Use light bullets.
