Largest: 500 Jeffery

Most felt recoil: 500 Jeffery, 10 lbs 4 oz rifle shooting 535 grain Woodleigh over 116 grains of Rel 15. That's right around 100 ft-lbs of recoil and got my attention. The biggest before that was factory loaded 400 grain Fed Prem in 416 Rigby. The Jeffery load was a whole new experience.
