Cayugad, All

What do you think the maximum effective range on a whitetail would be using the .50 Cal Encore Pro Hunter with 100 gr (2 pyro pellets) and 250 Shockwave?? Also, what about 130 pyro pellets (2 -50's and 1 30 gr). Havent heard how bad the recoil is with 150grof pyro. Would think the pro hunter design would help the recoil. I had a thumbhole .50 cal Omegaand it kicked like heck with 150 gr (3 pellets).
