I've been to a 3-gun where they wanted slugs (easier to patch, perhaps), and were recommending "Reduced Recoil". an usually get a five-pack for about $4-6.00. I needed 30 for the match I attended, but you should always pack up to twice as much ammo as the Match requires, in case of reshoots (equipment failure, scoring problems, etc). I saw a guy get two reshoots (on different stages) on the same day. That same day, I was a bit generous with my shooting (putting extra shots in the movers), then got a reshoot on a stage and had to borrow ammo! Lesson learned...
