I also have a CVA mag-bolt 150.I shoot the 225 powerbelt hollow points,pushed by 2 50 grain pyrodex pellets.they work great.I tried 3 of the 50 gr. pellets.they worked good , but the patterns were a little wider.with 2 the shots are tighter.
I have taken 6 deer with mine out to 145 yards,all were pass through with a blood trail that a blind man could follow.
never liked the areo tips,just me. the hollow points are great.

as for the instant knockdown, you only get that with the double shoulder hit or spine.lots of meat loss.
all the shots I have taken were rib shots (lung hits ).they only went 45 yards.

if you try the 225 hollow point , with lung shots , I think you will like them.

100 grains of pyrodex will push then out to 100 to 125 yards with no problem to take deer with.
