I have a bighorn, I shoot two 50 grain pellets (100 total). And a powerblet 348. At fifty off a rest I have hooked 2 together, but for some reason I pull the third about a inch.

I think that the max load for that gun was 120 grains. I am not sure but thats what I remember. I would like to try 150 grains but haven't done so yet.

Knight dosen't recommend powerbelts. I called and asked. But the gun shoots them so good I am not willing to switch.
