Here's something I'm curious about and I wonder about its practicality in the 5.7. It appears to be a conventional cup and core pistol bullet.
It seems most people are loading Hornet or similar varmint bullets in the 5.7 and I have not seen anyone commenting on how this Armscor bullet has worked in the FN. I'll have to buy 100 and see how they shoot at 1,700 fps. A gel test is probably also needed.
