I dont get the discrepancy in plated bullet use. Granted I havent used alot of them but I did buy 1000 158gr flatpoint bullets from Berrys, their thick plated ones, and was easily able to work up a few really nice loads with them. Ive also used some of their 9mm bullets and again, no issues. Now I did once buy some 240gr plated bullets from some company called PowerBond and those things were awful. They would tumble like tumbleweeds no matter. Terrible accuracy.
Plated bullets arent something I buy alot of but sometimes when I find a deal or just need something different for range ammo I will because so far Ive had ok luck with them.
OP, maybe try Berrys thick plate bullets and see how they work for you. The TP bullets are rated for a higher velocity than their regular line.
