Subsonic shoots best at 50yds and can be the most expensive. It may die and hit the ground before 150.
I like my mod 37s for accuracy and my 40x as a tote around rifle.
Butch- I have had best luck at 150 with Eley Tenex and Eley Match. Next best is RWS R50. Lapua Midas and other $20 a box stuff stunk at 150 yards. I can't beat Wolf Match Extra at 50 yards even with the Eley stuff.
I don't even shoot high velocity stuff anymore except when hunting. Wish I could find a nice clean 37.
