Tony Williams Wrote:If we were considering lead-cored bullets then I would definitely go for 6.5mm. With non-lead bullets it may be that a larger calibre is needed to get a reasonable weight. On the other hand, we don't want the weight to be too close to the 7.62mm or it won't be worth changing. So maybe 6.8mm would be the right compromise, but probably with a slightly bigger case and certainly with space for longer, more aerodynamic bullets than the 6.8 Rem.Concur with all above, except the 6.8 Rem -- free of the M16 mag length -- can be loaded with longer bullets.
