I switched to Limited last year after shooting Production for a long time. I did it in the middle of the season which was probably not the smartest way but I wanted to shoot both divisions at the last Nationals. It affected my performance in both. Stage planning, reloading, and movements are NOT the biggest challenges in my opinion. Yes, they are all important. The biggest challenge, however, is the different recoil impulse. For several months I just could not shoot major with the same speed and the same accuracy. I guess the major scoring has its reasons. I spent a lot of ammo (15K at least ) this winter shooting the dot drills, doubles, and bill drills. Mostly recoil management drills. Finally I feel like I am almost there now. Last weekend, I shot my production gun for a little bit and was happy to see how easy it has become after shooting major for a while. I believe I am a better shooter now because of the switch. One more thing: because switching could be detrimental to the performance at the beginning, it could also hurt your self image. You need to be aware of it and just keep on working.
