John, I meant that a 6.5mm plastic-cased LSAT with the same performance as the Grendel could have ammo with weight reduced by up to 40%. This is the weight saving currently achieved by plastic-cased 5.56mm LSAT over the standard brass-cased 5.56mm.
Having said that, I suspect that the bullet will form a higher percentage of the weight of a long-range intermediate than it does of 5.56mm M855, so maybe the weight saving won't be as great, but it should still be at least 30%.
