Hi,
Welcome to the forum. I too am not familiar with the Hunterbolt, but it should be up to the task of hunting out to at least 100 yards. Id stick to 2 pellets, as 3 wiill not be that much of an advantage.
How far will you be shooting at the max? If your really trying to reach out there, then 3 might be needed, but having just goten the rifle, Id stick to <100 yards, and 2 pellets.
Do you have all the accessories to go with the gun? Short starter, cleaning jag, speed loader, ect? What will you be shooting? Sabots or conical?
CVA's are a decent gun, so dont sell it short. I have yet to find a deer that cares what you shoot it with. Ive shot em with CVA sidelock, MDM's, T/C's, ect., and not a single one complained what type or brand of gun I used.
Good Luck, and practice practice practice before you hunt. The deer deserve that, at least.
