When I get the best load nailed down, I'll shoot a 3-shot group, shooting 2-shot groups during load work saves a lot of powder and wear & tear on the gun.....and me, even in the leadsled it really kicks with me behind it. One thing I noticed is the report, compared to the 376 Steyr, it's a very big bore boom instead of a bang, even my wife could tell the distinct difference when I shot it! This is something I never noticed when shooting it as a 500S&W.
Thanks,
Tim
