Eventually, as you move out further, you will want to switch to the more durable black sabots. Here is a website that sells the Harvester Crush Ribs. I have tried the sabots in the link belowwith your SSTs/Shockwaves. They load alot easier than with the sabots in that bullet package. The green sabots would give me an occasional flyer - right off the target paper. There are a couple of other posters here that have experienced the same thing.
Try the 50-pk plastic sabotsout! Then you can also start buying those XTPs and Gold Dots in 50 & 100-pk bulk. They are right down the reloading aisles in most hunting stores. Makes shooting alot cheaper.
