I have a Stephen Grant in .380 Center Fire Rook built on a miniature Martini Henry action. Really neat caliber because .380 CF is also 38 Long Colt. This little rifle puts round after round into an inch and a half cluster at 50 yards. My eyes open the groups up to about three inches at 100. It is a really neat, and with its 26 inch barrel, remarkably quiet crow wacker from the back deck.
