Very tough to bounce around all the time. You can get pretty close to tour normal shooting ability with about 400 rounds on a single day, but it's tough to wake up the next day with the same tuning. It takes months of repeated practice on the same platform to be consistently good behind the gun. Otherwise you're still thinking about how you shoot the gun and not fully tuned. If you consistently train multiple guns and keep the skills with multiple guns at a decent tuned level it becomes easier, but not easy. Optics to optics is better, optics to irons is the hardest. There is value in learning different platforms and making each gun "work" - sights track up and down, and return. oh....and make the bullets go where you want. CS
