The specs. for the current Gold Dot and HST are on the ATK website and the 147gr. Gold Dot has more penetration than the 147gr. HST in every test.
The FBI is Big on Penetration one would expect the new Gold Dot 147gr. G2 to perform better than the current 147gr. round.
Maybe the new G2 ammunition will penetrate like a Gold Dot and expand like a HST.
No one is talking about the the current Gold Dots. You claimed that the new Gold Dot G2 has "better penetration in Gel, Heavy Cloth, Steel, Wallboard, Plywood, Safety Glass" than the 147 grain HST. Those are pretty specific claims to be making if you don't have any actual data on the Gold Dot G2 to support those claims.
Much like the Hornady Critical Duty and Winchester Ranger Bonded, the Speer G2 is engineered to perform more consistently across the full spectrum of FBI barrier test protocols. Other loads offer better performance in specific test criteria, but don't do as well against other scenarios. Each end user must decide what performance parameters are most important to their possible engagement scenarios and what features are lawful in their jurisdictions.
Facts matter...Feelings Can Lie
That could be, but I wouldn't take my photos out of context. I only did one round. For all I know, that was the black sheep of the bunch or something. Agreed, it wasn't pretty, but it DID punch very deep and expand with near as I can tell 100% weight retention to over .68 when averaged and .73 when not. It's not necessarily better then the best HST's have done in tests, but it's right up there with most HST tests I've seen I have seen, AND it's a bonded bullet! Show me any other non boutique manufacturer 147gr bonded round that will expand like that. It wasn't gorgeous, and I wasn't as impressed as I had hoped to be, but I was still impressed enough to retire my HST's and that says quite a bit.
