Exactly the point. Smaller kills test a different part of the skills base. You don't need a £1000 scope to rangefind a 30 yarder accurately but if it's an inch kill and the wind is up you need more nerve and more skill and less luck.
Course design is about balance. I could put out a league course of 40 targets with four long standers (and here in SWEFTA we are allowed all of them at 45 yards with full size kills) and the rest of the targets at 25 yards, on the level, full size kill, no inchers, no minis. Most competitors are going to get all the 25 yarders, and someone might (not me though
) get all the standers for a clearance. But is that an attractive and enjoyable course, even though the worst shot walks off with 36 ex 40?
