I have had great success ordering directly from X-treme. I have been very pleased with everything I've ordered:
200gn RNFP, 44 Spl; 200gn FP, 45 ACP; 230gn HP, 45 ACP; 180gn FP, 40 S&W (10mm); 158gn FP, 38/357; 125gn FP, 38/357; 158gn SWC, 38/357. 158gn RNFP, 38/357.
All of these work great for my applications. However, I built up most all my inventory a couple years ago; and maybe things have changed since then.
200 grain .40 caliber bullets and loaded them to about 1150 ftp for my Glock 20. They all tumbled and key-holed at that speed.
disseminator, Haven't tried that particular bullet. I do use their 180gn FP for my Glock 20 (and 29). I have stock and Lone Wolf barrels for both. Using 8.8gn of AA#5 (this is for 10mm folks,
not 40 S&W), they run 1063 f/s through the G20; and go nice n straight. I have since backed it down to 8.4 grains for my personal preference, but haven't chrono'd them at that charge weight. I've also ran them up to over 1100 f/s using HS-6, and still had good luck with them going straight.
Obviously, I'm not driving my 180's as hard as your are your 200's. But that's my experience.
I pay no attention to the "maximum velocity" recommendations often printed on the box (or website) of plated bullets. The concept is silly. Plating breakdown is about pressure, not velocity. Furthermore, the whole system is very dynamic (to say the least!) and can not be put into a specific velocity parameter. Knowing that 10mm is a very potent round, I make the choice to drive plated bullets only to range fodder applications. Anything stronger than that (high-recoil defense level practice), and I move to jacketed bullets.
