Evil Monkey said:Why would you practice with 22lr and carry something else?
Gun handling skills, efficient movement, practicing the execution of good fundamentals, seeing what you need to see when you need to see it, etc. There's a lot to shooting well besides recoil. A lot of top shooters still know the value of a .22.
It's true one has to have trigger time with their primary gun, but many of the necessary skills needed to run it efficiently and well don't have to be done with CF ammo. Heck, for that matter, many of these skills can be worked on with no ammo (i.e. dry fire).
IMO, one can theoretically learn to shoot well starting off with their CF gun, but their chances of attaining good proficiency and avoiding bad habits over the long run are a lot higher if they start off with a .22. Show me a shooter who categorically poo-poos the value of a .22, and I'll very likely be able to show you a mediocre-at-best shooter.
