I don't believe that Berry uses an ultra-fine molding setup. (But then for making plated bullets, why would you need one?) When they core a bullet to make a Hollow Base, they place a whopper of a core in the mold. And that's just fine for Hollow Base. But when you use the same diameter core to make a HP, the size is rather large. Because the core is large, then the meplat portion of the bullet gets ridiculously large. To me it's that large frontal area that upsets the feeding.
I've had the same results of poor feeding from FPRN, another bullet style with a large meplat. That's a very common bullet for 357Sig and 40S&W, but it's not common in 9mm. I once tried some very good looking jacketed 124gr FPRN from Zero. I had to get them down to 0.980" OAL to get them to feed well.
So my issues with the Berry Target HP are not specifically with Berry. My guns simply seem to have issues with any bullet with a large frontal area.
