Your going to have to find a heavier or faster round than WIn white box. Look for something in 124gr.
I use a CZ75 ST IPSC to shoot pins. Its CZ's gun built for Limited IPSC, which is what I bought it for, pins is good pratice for shooting steel. My gun is a .40 and clears the table nicely but once in a while I get lay down and so do the guys shooting 1911's.
My best time is 2.85. I usually shoot in the mid 3's. Keeping shooting pins and dry fire at home and your time will come down.
