Some might remember I have a Ruger super blackhawk 44 magnum and it was leading badly. Well long story short I sent it back to Ruger for the second time and it appears they have worked it over. New barrel per the paper included, which appears to have an 11 degree forcing cone cut. And a new cylinder though it's not mentioned.
Previously by slugging my cylinder throats and measuring with calipers, I had 4 at .433 and 2 at .434. Now by the same method all measure .432. Yes I know this is not the best method but it's all I have.
I slugged the bore and it measured .429. I feel a slight resistance at the threads, but so little that I can push the slug through with my thumb on the brass rod. All of my thumb force, but still that ain't much when you're talking compressing lead. So I'm thinking maybe it's not a thread restriction but a burr or irregularity in the rifling. Opinions?
It appears they tested it with lead bullets instead of copper bullets also.
So, after 4 years of frustration, minimal enjoyment and shooting, I have hope.
I'm going to shoot it before I do anything. If need be I'll fire lap it, we'll see bout that though.
I just wanted to share this little piece of happiness with y'all.
Thanks for listening.
