Not really. 50 rounds of FTX for my 45 is the better part of $60ish. I've seen the 5.7 Gold Dot advertised, nobody actually has it for sale yet, for $35 for 50 rounds. That's also significantly less than some of the other high performance offerings from the various 5.7 ammo sources.VERY pricey.
It doesn't hurt to have AP ammo, but for typical self-defense I see little use in it unless you are in a war zone. Therefore I prefer ammo that penetrates soft tissue to 12-16 inches and expands instead of tumbling or fragmenting. YMMV
but also remember that about 2000 fps is where that temporary stretch cavity can become permanent. A 40gr bullet at 1790 fps may lack that ability, and may only cause damage by direct impact of it's path. We shall see. I'm all for the round as it will bring more attention to it, and hope that other places start loading for it too.It doesn't hurt to have AP ammo, but for typical self-defense I see little use in it unless you are in a war zone.

I've never been too interested in SS190. I'm satisfied with SB193 and SS198. I don't even care that SS198 hasn't penetrated too deeply in my ballistic gelatin. With 50 rounds, I should be able to dissuade most attacks.Just as an FYI...SS195/198 will slightly dent .125 6al4v titanium plate. SS 190 whistles right through.
The SS198LR really isn't the best option for armor penetration since it's basically the "leavings" of the original SS190 with the steel penetrator. Despite their impressive speed, the 27gr. bullets are limited by having an aluminum core with swaged on copper jacket left open front and back. In penetration tests you can see the core extruded out the back with the bullet embedded in the target material. This is a case where the core is lighter than the jacket and the base is wide open for the core to be pressed out the back. Sure if you get it going fast enough it's going to punch through Kevlar, but steel plate will be difficult. This is why you see the custom bullet loaders using solid copper slugs in the 32-34gr. weight - and they have certainly tried to go lighter but the bullets didn't perform as well. Also, even the all-copper bullets are still relatively "soft" when they hit steel, though the nose tends to collapse inward aiding penetration.Please save yourself some money and look at Midwest Gun Works.......SS198 is $28 or less per box. FYI
Penetrating Kevlar isn't all about having a pointy tip. A JHP with the right kind of jacket can also get through and even a JHP with plenty of exposed lead such as the Armscor 40gr. JHP can penetrate TL3A when fired at .22 TCM velocities of 2,050-2,100fps. I would expect Armscor's 39gr. stub-nose JHP to be very good at defeating kevlar because the jacket edges go all the way to the hollow nose, so when it hits - spinning like a tiny "hole saw" it tends to slice the fibers. With the newer polyethylene layered vests I think a "cutter nose" might work better than a point - unless of course that point is shaped like a 3 or 4 sided "bodkin" which will tend to cut rather than just push through.Given that the 5.7 28mm has the reputatiion as "Cop killer". I'll bet you're correct. I'd like to see what it'll do though.
