Exactly! Bryan Litz has also found that BC goes up when a bullet is highly stabilized, as does accuracy, and he shot and won a match with a .308 Win 9" twist barrel and 215 Hybrid bullets- a faster than common twist for that chambering, which illustrates the point.
Hornady recommends a minimum 8" twist for their 162gr A-Max Sierra recommends at least 8.5" twist for the 175gr MK and 8" for the 180gr MK Barnes recommends 9" OR FASTER for the 168gr LRX Berger's twist calculator shows a 9" twist as being marginal for the 180 VLD at sea level and 32 degF
The MRC mag allows long bullets seated out of the powder column, and if the barrel is throated and twisted accordingly, there's no bullet it won't shoot and nothing it won't do.
An 8" twist will stack the 110gr bullets as well as the 180 VLD. A 9" will stack the 110's, and will marginally stabilize the 180's. Where's the downside to the 8" twist?
We usually have to suffer twist concessions with production rifles. Why not choose correctly from the get-go if a manufacturer is giving us the opportunity to choose?
