Royce,

Well, the Avenger is a lot easier to shoot well. When I need to kill a pest, I always grab the Avenger because I know it's going to be a good accurate hit, even from an improvised position.

The beauty of the Hatsan, or any break-barrel, is that all you need is some pellets, and the rifle. The PCP needs recharging. That said, this PCP I have the regulator at about 1900 psi. The reservoir can be filled up to 4500 psi. This gives about 70+ shots before the reservoir falls below regulator pressure. So unless you are shooting high volume, it's really not such a handicap. The recharge using the hand pump takes about 150 pumps, give or take.

I've found that the break-barrel can be picky about what pellets it likes. Where the PCP seems to shoot very good with anything I've put in it.

The 22 or 25 can actually both be fairly equal in the wind. The BC of the typical pellets is around .025, give or take...in other words it's really low, considering a 22LR 40gr is about .120 or so. So the difference in the windage between 22 and 25 cal pellets isn't really significant to a casual shooter like me.

Now, if you are going with a PCP, you will have enough power to utilize the airgun slugs that are out there. They tend to have BC around .09 or so. These projectiles will buck the wind and retain energy much better, and many target shooters use them out to 100 yards or further. I've never tried the slugs myself, but probably will get around to it eventually.

As far as pellet availability, 22 and 177 cal are the most popular, and mostly available, even at walmart most times. When you veer off into other calibers, supply can get a bit more difficult, and expensive. 25 cal isn't too bad though, but you won't find 25 cal at walmart. I order them online.

Pyramyd Air is a good online source for just about everything airgun related. Also, Airgun Depot. Both are actually the same company. Order from either and they ship from Pyramyd Air's warehouse.
