I shoot a 44 1/2 in 38-55 with a 1-15 Badger Barrel. One of the bullets I use is the one you mentioned. I use this in silhouette and in NRA matches at 600 yds. I use blackpowder, compressed 46gr of FFF. No trouble it is stable at that distance, I have not gone further. On the paper at 600 yds it is more than capable of holding its' own, I do not have to take a back seat to anyone at this distance. My rifle does better than I am able to.
