I'm 33, legged out at 30, my vision is excellent. Just wanted to go to a bolt gun. I have a Tubb 2000 that I got several years before which saw only LR use. As soon as I legged out, I switched over to the T2K for most competitions. I still use the AR for CMP events. I still shoot local EIC matches and will be going to my 2nd CMP nationals this year (actually doing both CMP and NRA with the schedule change this year).
OK, the T2K ain't an old school match rifle, but I'd still shoot one if a Tubb or a tubegun weren't available. I like the better sights and greater inherent accuracy with the bolt guns. I also find the rapid fires more challenging with the bolt gun. Deep down, I believe that a bolt gun makes one better at rapid fire stages with a semi-auto (you really have to learn cadence unlike with a semi-auto).
6XC for XTC, but I've thought about throwing my Palma barrel on the Tubb gun and just shooting it XTC for the heck of it.
