I believe a Armalite AR- 10 can be had with a 9.25 twist. Mine's a 10. It does the 87 V-Max ok. The 95sst's look like someone threw a handfull of gravel at the target..maybe that was me.. The 95 and 105 VLD's also suck. The only reason I have those longer bullits is my 6br is a 8 twist. It(6br) also likes the 107 sierra's which can be hard to find at times. Just repeating...kinda what your saying D. BUT..There is a bit of black magic going on with some barrels.
