I've had my cva wolf for two seasons and have shot quite a few rounds through it. I'll tell ya what I can. My hunting load is 90 grains of American Pioneer with a 240 grain tc cheap shot. Worked it up with the help of some of the guys in here just before last season. Never seen deer drop so fast. I have tried a variety of magnum load through mine but found that because the gun is so light they often decrease your accuracy unless you have a really stable rest. Pyrodex RS loose or pellets also work really well and my stepbrother has always used powerbelts in his. He's had some luck. The best idea is to just experiment with different loads. As far as cleaning, Clean it after each time you shoot it and do a total cleaning after season when getting ready to store it. Ask the guys in the forum for help.
