I bought 250 rounds of berrys 155 gr 40s&w and 255 rounds in 180gr. I have loaded a few test loads with different powders and noticed two of the four loads were keyholed at 15 yds. I have not tried the 180's yet. For those of you that have tried these bullets, what velocity is do you recommend with these copper plated bullets. I believe their site say 1200 fps or under. I seem to remember reading somewhere to say at 1000 fps or under. Have I wasted my $$ or can these bullets be made to work.
