Hey Warp, hope your day's going well.
I was responding to the OP, not to any of the subsequent posts about Speer Lawmen or any other brand, with the spirit of my post being to define what "premium FMJ" would be. For example, for training and practice I go with SG Ammo or Freedom munitions TMJ/FMJ for ~.20 per round. Premium isn't an adjective most would ascribe to this type of ammo. However, I load it in my gun. It goes bang. If I do my part, the bullet goes where I want it to go. Now, if someone secretly swapped in a magazine of Acme Premium FMJ rounds, I can't fathom an appreciable difference; so long as I apply the fundamentals and the round goes off when the trigger is pulled and strikes where intended, what have I gained from shooting Acme?
If Speer FMJ is premium ammunition, what makes it so? And indeed, .22 per is much better than my area Wal-marts, but I haven't paid those prices in years.
TL; DR: In lieu of an actual definition of "premium FMJ" with observable differences, the best I can guess is that anyone who says they have such a thing is probably trying to sell it to you, and probably at a higher price-after all, it's premium (whatever that means).
