Looks like bad quality control. Where did you buys these? I'd contact them to let them know about the poor consistency. Worse comes to worse, you may end up with a couple tins of free pellets.
My experience has been largely the same. pic 1 flairs have completely different shape 2 head not square with body 3 die not filled out.......insufficient tail punch force? 4 lack of symmetry on flair, different angle on each side At 50 yd, 3 or 4 shots out of ten will nearly touch each other while the rest are 1 - 2 inches outside. Disappointing. Incidentally, the Baracuda magnums are just as bad.
when did you guys pick up your pellets I got a tin of the Sniper mags .177 last year ......
I recently tuned my regulated .177 PCP to over 30fpe... I find that 16.2gr JSB Beasts shoot very consistently with this gun. Sub .75" groups almost every time at fifty yards, unsorted and straight from the tin. So I have a nice pairing and am happy with that. Great.
