I've never had a problem with 90 grain Hornady XTP feeding in my .380, a Grendel P12. I'm looking to get a P3AT soon and will play with ammo choices in it. I'm not sure whether a hollowpoint is all that good in the caliber considering marginal penetration, but I want a flat nose profile, not a FMJ ball. Those Winchester flat nose "green" loads don't feed well in my Grendel, but I might consider 'em in the P3AT if it feeds well with 'em. They hang on the feed ramp occasionally in the Grendel. I handload a SWC 105 grainer that feeds fine. That one is accurate, heavy, and I have a load that pushes 220 ft lbs with it that doesn't have excessive pressure. That's about all I can get out of a .380 and that might be the load I go with in the future.
As far as that Hawes site stating ANY .380 load can top a good .38 special, well, he's pretty full of it, me thinks. I'll trust a +P 158 grain hollow point out of my 2" at 290 ft lbs any day over any .380 load for both penetration and expansion. It will expand and still deliver the goods. I feel much better about totin' .38 than .380, but the allure of a tiny little pocket gun is strong, I'll admit, for deep concealment.
