Interesting link, Sabotloader. My current load (240 grain xtp, 80gr triple 7), has 17lb of recoil. Compare that with the 150 gr triple 7 pellet load and a 250 grain shockwave: 41lbs of smack. You look at the the recoil table from
http://www.chuckhawks.com/recoil_table.htm and 17lbs is about what you get from a .270, and 41lbs is a tad MORE than a 9lb 375 H&H gun will kick.
