If you want to REALLY tune up your handloads, go to www.ballisticproducts.com and browse their site. Their info and recommendations are second to none. Using their components, you can customize your patterns and velocities, something that is not that easy using "generic" shotcups and hulls.
MEC is good equipment. You can turn out excellent loads with their most inexpensive unit.
A word of caution....a lot of people look at shotgun reloading as a casual activity that isn't very complicated and inherently easy. While it is very enjoyable, it can also be a very, very dangerous undertaking if you aren't careful. Use ONLY SPECIFIED components, and don't substitute shotcups, hulls, or other components. Different hulls and different shotcups rather than what the loading manual specifies can cause very dangerous chamber pressures.
It's easy, and it's FUN, but it requires attention to detail and caution if you want it to be safe. /ubbthreads/images/graemlins/wink.gif
