+1 A 20BR will get the 55gr Bergers closer to 3700FPS and with a .381 BC. A .20 cal 40gr Vmax has a higher BC than the 55gr BT in .22 and you can send the .20 down range at over 4000FPS.
Once you try a High Power .20 for varmints you won't go back. I compete side by side with my buddy's shooting 22-250' and 22-250 AI's all day long with my 20 Practical and a 40gr Vmax @ 3900 FPS.
Heck it even hangs with my 6mm-06 shooting 70gr Nosler BT's @ 3700+ FPS (modest, have not run through the crono yet, my smith says it should be closer to 3800-3900)
.20 cals also have less recoil allowing you to see the hits, although I would put a mini break on a .20BR to make sure the RED MIST was in full effect through my glass, THAT is what makes PD shooting so much fun.
