|I bought 4 boxes of this stuff- the cases were nice nickle but the powder was smokey and dirty! After the first 6 from my GP-100 I began looking around at the other bays to make sure all that smoke was coming from me. It was. I blew through the rest and saved my cases for reloading. In general the accuracy was okay- I could maintain a good grouping with the occasional flier.
After a few reloads I really had to palm the ejector rod to pop these cases free- they didn't just expand, they were stuck! Later when I cleaned the pistol I found that some of the muck refused to lift from the metal. Hopp's no. 9 was like water- I really had to throw in an extra pound of elbow grease to clean up. I won't buy more of this- In a revolver it was tough to clean up- I'd hate to send this through my Kimber. Not happening.|
