Comparison Of Grendel 6.5mm.docVIP

Comparison of 5.56 and 55gr with 6.5 Grendel and 144 gr Lapua FMJ Alexander Arms currently produces four factory loads: (1) 123 Lapua Scenar, (2) 129 Hornady SST, (3) 120 Nosler Ballistic Tip, and (4) 90 Speer TNT. They are shown sectioned below, along with a 144 Lapua FMJBT. The “sweet spot” for bullet weight in the 6.5 Grendel case is around 120 grains, of which many, many 6.5mm bullets are available, but the cartridge exhibits its built-in flexibility by handling a wide range of common 6.5mm competition and hunting bullets from 85- to 144-grains.
