Too much pandering to the slow twist and the Grendel.
The issue is most definitely the issue, but not pandering to any specific twist. Being Solid copper, Barnes bullet lack the density to achieve the same weight to length ration that can be achieved with "conventional" boolets. The 130 TSX-FB & 127LRX-BT are most likely the longest Barnes can make a bullet & still maintain stability at sea level with ALL cartridges.
When comparing the Cutting Edge G05 130 Grain MTH to the 140 Grain Berger H-VLD, the G05 was just as long or slightly longer than the "conventional" design of the Berger. By stepping up to the CEB 140 Grainer (G10), the bullet was quite a bit longer than the 140 Berger of the same weight. The Berger will stabillize in my 8.4 twist Obermeyer while the G10 will not (much to my chagrin).
Without a dense core, Mono-metal bullets will always be longer than conventionals of the same weight, thus requiring a faster twist to stabilize OR by dropping the weight & the OAL of the bullet to ensure stabilization as Barnes is doing as of now; the problem being, BC suffers, badly.
