M77 MKII RSI in 243 barrel twist rate ?

--------------------------------------------------------------------------------

Could someone tell me what the barrel twist rate is on a Ruger
M77 MKII RSI in 243 caliber ?

What is the best bullet weight or factory load to use
with the 18.5 inch barrel on the RSI ?

Not too difficult to determine for yourself. Here's how Larry Potterfield does it:

Thanks

Ruger website says it is a 1 in 9 twist

Thank you for asking and posting this. Hate to admit that each past time I found out, I'd forget. My two youngest kids share a RSI in .243
