.375's may be heavier, generally, than .33 mags.
I think a lot of this is a function of higher velocity causing more abrupt recoil. The heavier, slower projectiles seem to push more and jolt less. For example, I don't find the .500 NE that objectionable. A Merkel double weighing 10#'s gives a big push, not that much "jolt". A .300 Wby with heavy bullets tends to jolt, the .340 Wby, even more so.
I guess it's what one likes and personal preference based on experience. As they say, one man's trash is another man's treasure...
