So I just noticed I bought 5 boxes of Barnes 200 grain .451 XPB Colt bullets. These bullets only have 1 groove, where the 460 SW XPB has 2 grooves. I thought I was buying the 460 SW XPB with the two grooves, which I have loaded before. Can these single groove Colt bullets be useful with the 450 (AR) or are the now paper weights? Thanks for any insight to this issue, Marc
