I'm shopping for a bolt action rifle for medium to medium heavy game. I was looking at the 243 but think I like the 308 better. 1 in 10 twist would handle the heavier bullets best and would allow me to load the cartridges to the rifling. But the rifle I'm considering is the Left Handed Tikka stainless lite, and it's only offered in a 1 in 11 twist. Significance?
