I have yet to see anyone disprove the data published by Buffalo Bore. Underwoods provides no information regarding the barrel length or gun used so it is meaningless in relation to your argument. Buffalo Bore publishes specific data from specific guns. You cannot do any better than that.
Here from the beloved Double Tap - a favorite of 10mm lovers
Caliber : 10mm
Bullet : 180gr. Nosler JHP
Ballistics : 180gr. @ 1305fps/ 681 ft/lbs- Glock 20 (4.6" barrel)
1120fps / 501 ft lbs 100yds Glock 20
Glock 29 - 1240fps (3 7/8" barrel closest to the GP100)
Caliber: 357 Magnum
Bullet: 180gr. Wide Flat Nose Gas Check Hardcast
Velocity: 1300fps / 4" Ruger GP-100
1420fps / 6"bbl S&W 686
Facts are hard things if you want to pretend that the 10mm is more gun than a .357 - Sorry
