Don't discount those light bullets if they are good bullets. When I tested the Hornady .357 125 gr. XTP in the .358 SOCOM, using AR-COMP powder in my 24 inch barrel, I achieved 2850 fps easily without pushing things past 36,000 psi. Another powder likely would have given me higher velocities. I did the same for lightweight .40 caliber XTPs in the .400 SOCOM. In both calibers, I was honestly expecting the bullets to come apart in the air, and if not that, completely blow up if they hit anything substantial.
In drywall testing, two layers of drywall, 3.5 inches apart, and water jugs set up behind the drywall, not only did the XTPs make it through both layers of drywall, they completely disintegrated the first gallon jug of water and split the second jug of water. The bullets did shed some lead and weight, but they did not blow completely up. They did not group real well, but better than I expected, namely 3-4 inches for 5 shots at 100 yards. Recoil, what recoil? First time I shot them, if not for the water jug exploding I would have questioned if the bullet had left the barrel.
So while these small high speed bullets may seem silly, with the right bullets they do have a use. Now if Midway would just bring those Hornady Critical Defense bullets, 110 gr. .357 spitzers, back on sale, I would really like to try some of them and see if they can flatten out the trajectory some and retain some of that velocity. Those blunt low B.C. little lightweight XTPs shed velocity like a feather and do not shoot anywhere near as flat as one might suspect given their high muzzle velocity.
