Yep I do, tested a crap load of them including the SS models. That SPR250 will get you to 470 with a .32 bb. With a .28 it should get you right where you want. My test rifle was a fully hopped up VSR all PDI.

HA! That makes me laugh. Have you ever been to a field? You can't just throw in heavier bb's and you're set. You chrono with .20g's, always.

I must have misunderstood you... It seemed like you were saying to "throw in .20g's" and that will get you "right where you want". Meaning that, once you just used BB's lighter than .20g's, you would be set, which is not the case at all...
