Looks like the jacket is fully perforated to the core. Somebody PLEASE shoot some of these into some ordnance gelatin! I bet they deform irregularly and tumble or veer like heck!
Disclaimer: The following is just my opinion, and I don't hunt either, so add that to the mix,,,,
But, in the assumption that the nose was indeed perforated to the core,,, (I'm not 100% convinced that it is) does it really matter?
Besides SD (and perhaps hunting??), I'm not sure what other shooting activity benefits from projo's that,
after hitting the original target, do better by resisting deformation and / or tumble. Perhaps there are folks who use their 38/357 for SD (and/or hunting?) and prefer a flat-nose projo over all the other available options?
For my intended purposes, I place emphasis on consistent accuracy from the muzzle to the point of impact, and what happens to the projo after impact is irrelevant.
I've loaded several thousand of Jakes Match Winner's in 9mm, and I've been very impressed with the results. I fully anticipate that Jakes 38/357 offering would be just as impressive for my needs, smiley face or not.
As always, YMMV
