dp - that is the exact same load I shoot out of both of my 45 LRH barrels with similar results. Actually I was getting slightly better groups at 100 yds with 70 gr of Pyro P but because I wasshooting open sights, I couldn't get the rear sight down low enough with the 70 gr charge and I had to boost it up to 80 gr.
But I like these barrels. And that 200 gr XTP is a great bullet.
BTW Good shooting.
