Striperguy,
There are allot of people here with allot of experience. There are a few things that always tend to bring up lively discussions. Some of these include powerbelt performance, or lack thereof, 777 crud rings, Shockwave performance at close range, types of 209 primers, old style vs inline, iron sights vs scopes, pellets vs loose, on and on.
Most of the time it is lively, positive, polite and infomative like this thread has been. One kinda has to wade through all the great info and figure out what works for them. What works for me, even in the same gun, might not work for you.
Bottom line on the question you ask, if you think you are going to shoot within 100 yards,I would suggest perhaps the Hornady XTP or some other 250 to 300 grain hollow point style bullet and sabot. If you might need more than 100 yards, I would stick with the shockwaves. Maybe when using the shockwaves at close range move over to shoulder shots and move to double lung/heart shots at longer range.
Welcome to the forum, you'll learn allot, I know I have.
Good luck
Hank
