Hello I have been looking for a savage large shank 300 ultra , I cannot find one anywhere. I might have the opportunity to buy a small shank 116 in 300 rum, or a rem 700 300 ultra. I have been reading about the small shanks not being big enough for them. Well I looked and the size of the barrels on criterions site ,a savage small shank 1 1/16 x 20 , and the size of the remington is 1 1/16 x 16. Is there something im missing as to why I should stay away from the small shank for a custom?? Or would it be wise to steer clear
