According to R&R Arms advertisements, the twist rate for the T/C Icon .243 Win is 1 in 12" for some strange reason (otherwise I've not been able to ascertain with any level of confidence a different alleged twist rate from a reliable or semi-reliable source).

I've read that the original twist rate for the 6mm Remington (then called the .244 Remington), which led to its losing the race to .243 Win, was 1 in 12", purportedly which was supposed to shoot the largest bullet of a 90 grain flat-based spitzer. (Before Remington later renamed the .244 to 6mm Rem and changed the twist to 1 in 9" to accomodate up to 105/107 gr bullets).

So, the question is, would I have any reason to suppose my T/C Icon might be able to shoot anything larger than that with accuracy, such as a 95 gr flat-based spitzer, or 85-90 gr boattail? I know - ya don't know til ya try, but should I even try or can I safely assume that a 90 flat-base is the longest lead/copper bullet which can stabilized? Thanks.
