Those 60's are meant for the 25-20. Yes they will work in any 25 rifle but you will not likely find them very accurate. If you woulf like to get rid of them, I would love to buy from you.. (PM Me if so)
I also agree with INRUT24/7 try some in the 75Gr size. these are meant for your purpose. 4831 is a good powder in the 25-06 too!!
BTW, congrats on the new "toy"!
