I've actually had a little bit better with 40 grain at 3400fps, but we are nearly splitting hairs better. 4 out of 5 at 1/2" grouping at 200yds a few times. Those 50 grainers are a great bullet and so far and no flyer in testing of that load. I bought another 1000 yesterday. When I get to shoot a bit more I bet I'll be close to getting that 1/2" grouping with the 50's at 200yds.
