Published data, sure.
There was some USPSA Limited Major shooting done with heavy bullets and fast burning powder. Felt recoil and less muzzle rise were the justification. Pressures were no doubt high but the sturdy race guns held it.

If they were sturdy, the power factor for major wouldn't have been reduced from 175 to 165?
Though I doubt there was ever a public announcement to the effect, there was an "understanding" among the membership that major was reduced to 165 because 175 was too hard on .40 guns.
