I have a rifle in the same 38-55 caliber. Mine is the Browning copy of the Winchester High Wall. I bought a bunch of the cast silver bullets for it and it shoots them just great. I only wish I had more time to spend with it. Have to get the muzzleloaders shot first and am getting way behind. Forgot to add that it is the Browning copy of the Winchester Highwall that was a copy of the original Browning Highwall. Now that really goes around doesn't it?
