Quote:Yet, we see steel replacing lead in military ammo. That will cause the bullet to behave differently on impact. The 5.56 example suggests that a "green" 100 grain 6.5 projectile might do as well as the lead core 147gr FMJ.I agree. Question is, what velocity would be required of a 100gr steel-core bullet? Would it still be higher than feasible with 6.5 Grendel?
Quote:Fortunately, the Lehigh Defense 95 grain Controlled Chaos bullet is available and inexpensive enough to try on a variety of targets. The results could prove interesting.Perhaps, but I'm skeptical of the usefulness of data from brass bullet performance being applicable to steel-core projectiles.
Some time back, one of the guys on the MG&A forum shot CMUs with different calibers. In that test, a solid brass 6.5mm bullet outperformed lead-core 7.62 NATO. However, IIRC when Bill W shot a steel plate with the Barnes 110gr brass solid, it failed to punch through.
I'm especially leery of the Lehigh hollowpoint bullet in this regard, because the nose has got to be much more fragile and subject to deformation or break up than a hardened steel penetrator. I think that 7.62x39 steel-core bullets -- being in the 6.5 Grendel weight range -- would permit a better evaluation of CMU-busting ability, despite their larger diameter. Of course, the steel-core 6.5x55 112gr AP would be nearly ideal, but who knows where to get any.*
