Check the cylinder throats first; I've had to have three cylinders reamed for my 2 BH's as they were random in size, but all smaller than .452. My 45acp cylinder was actually splitting the cases around the base of the bullet, solved when reamed to .452. Accuracy also dramatically improved. As stated Ruger customer service is great and they strive for satisfaction.
