Some do, overall I guess they have not caught on for various reasons. Distribution intermittent, Weight perhaps, stocks may not fit the rules specs.
Basically you have Anschutz and CZ, and then a little bit of everything else.
I would not mind having one of the toggle bolt guns.
Reality of the time allotment:
More than enough time to make the shots.
Often, if you cant seem to aquire the target at first, lower the gun, remount, breathe again, re-aquire.
I have not personally witnessed any of the higher class shooters who shoot quickly, though they will have some 30 second to a minute or more, left when done with a relay.
I would say its both hard and easy.. the sport.
it is hard to shoot a great score unless you have a lot of practice or some natural talent. It is easy to shoot just well enough, to make you come back and shoot again. And of course buy more Shooting Irons.
Actually I shoot better scores with a peep sighted Lever gun at the larger targets, than I do with a scope on smaller targets.
Man, I am already thinking of the next one...and I have not even shot this thing yet!! ( its an OCD thing)
Just put on the recoil pad today.
