Hello 9.3,
I've fired only at inanimate targets with these 200g bullets, and not nearly as much as you have. However the Lyman 358430 and its clones have a very blunt nose that approaches the old Super Police and British Mk. 1/1Z 200g lead military loads. The 200g NEI 169A's extremely long, tapered ogive more nearly approximates the shape (and characteristics, I think) of the later 178g British Mk. 2/2Z FMJ bullet.
Shooting at water jugs, wool overcoats and the like, I definitely observed that the lower-velocity 590-610 fps bullets destabilized and tumbled more consistently and sooner after target penetration, than did hotter-loaded .38 S&W or .38 Special 200g @ 650-725 fps.
Your thoughts?
