I am looking to buy a 460 Rowland carbine. I would like to shoot 45 A.C.P. for fun then change over to 460 Rowland when playing in the woods. Are there any problems doing that? How accurate is it with the 45 A.C.P.? How safe is it shooting the 45 A.C.P.? I just read about some one having a bang because bullets set back in the case under fire. According to him it broke his frame and hurt his hand. If the 45 A.C.P. is a problem can you just down load the 460 Rowland with no problems? Speaking of reloading, I can't find any loading data in any of my books on the 460 Rowland. I guess that the people that sell the carbine have that information? Thank you much for any information you can offer.
