I am very proud of my son and his quest for his Ph.D in physics. Do you realize how few people obtain the Ph.D status in Physics in the USA? I also have a degree as a licensed physical therapist and am very science oriented.
I weigh 280 lbs and am an avid powerlifter. Still recoil sensitive, and believe recoil is a much bigger factor than inherent accuracy in determining ultimate accuracy.
Yes, i've noticed that my lightest weight rifle in 270 WSM recoils about the same as the highest weight rifle I've ever owned, the M1000 Browning in 270 WSM. With the right stock and recoil pad, the 270 WSM can have less perceived recoil than the 270 WIN. Believe it's all in the first few milliseconds of ignition.
Have a Savage in 22-250 and really like the accutrigger, but can duplicate with simple trigger adjustment for free in many rifles. Lately I've become a fan of the Winchester rifles due to good stock design, but this might change.
