Dumprat,
I built a 338-06 on a pre-64 Mod.70 action several years ago and killed two or three elk in timber with it. It performed perfectly. As I am sure you know it is not a long range round but for close quarters using a 250 grain Nosler Partition it was very good medicine. I built it using a feather weight Win. barrel so it was not pleasant to shoot at the range but in the brush who notices! I would worry a little on grizzlies though.------------Bill
