147gr Win white box is a great choice.
A friend and I put 400 147s through my Shadow at an IPSC match today. We (the friend, the Shadow, and I) had great fun and did well.
As of today, that's 1000 rounds through and not a hint of a problem. It was snowing and then raining all day, so I got to gaze into, dry and oil its oh-so-cleverly-designed innards again tonight. This thing cleans up real easy.
ResOps, get lotsa ammo or you'll be forever feeling like you've not got enough on hand.
Suggest, since you want to compete in IPSC, that you look at the CR Speed or Double Alpha line of double belts - both very stiff and made for competition. The Blade-Tech kydex holster molded for SP-01s is a very secure way to go, and the draw stroke is not impeded in any way.
Nice to get your reports. Oh, by the way, is your daughter's name Shadow, or am I confused.
