I just cannot understand why anyone these days would still do 10 twist 243's or 308s with an 11.25. Really how hard is it to just order faster twist barrels? Those who shoot a lot will be way more likely to buy an 8 twist 243 that a 10 twist. And those who think 10 is great probably won't even look what twist it is anyways because they are not into shooting enough to really care.
I think this is the long and the short of it.
