The 25 Souper . . Yea
Jackie, I see this link is a little old, but "The answer to your question is "Yes" it has been done to the 25-08, it is the 25 Souper" . . and a D@&M good shooter is it too . . I have one and Love it. . .
I first built a 25-06 AI, on a 98' Vz24, I could not get that caliber to shoot, no matter what I did, it would not hit the same place twice on a 8.5x11" piece of paper. After months of messing with it I took it over to my GS friend one night and pulled the barrel off . . I said to him "I'm Trashing this piece of C _ _ P . . - order me a new barrel . . He said to hold on to my skivies . . let's see what we can make with this left over piece of barrel . . with some modifying we got the 25 Souper Reamer to "Just" make it. I had tried all of the bullets and powders through the AI, so I had a good collection of powders and bullets to start the new one with. I ordered a set of dies from RCBS, and away we went.
It took about 3 bullets and 4 powders for it to settle in with, but it finally did, and when it did, it will put 5 - 89 gr. Sierra bullets into one hole for as long as you want to shoot it . . at 3350 fps.. I hasve killed several nice deer with it, with one shot kills. I even took a Turkeys head off with it one afternoon at 96 yards, what is not to like about a rifle that shoots that good. . .
I had a 25-06 that I built back in the early 70's and shot the barrel off it, always wanted a 25AI, but not any more, this 25 Souper does more than fill the bill. Light on recoil, fast, and accurate. I even shot a pig with it one weekend, dropped him in his tracks, "Bullet Placement" . . !!
So the answer is . . it is a "great caliber" - especially with all the .308 brass laying around . . it doesn't seem to be case sensitive either, it likes it all. I am remote right now and don't have the loading info with me. I do know that it was a Shaw Barrel, 1:10 I believe, could check if you need that info.
