I'm planning a new toy, a new rifle for vermin. I think I have narrowed it down to either a .204 ruger or a .223 rem. I have a tikka t3 at present and can not fault it so was looking on there website and there is two twist rates for the .223, 1:8 and 1:12. My question being in the real world what effect would the different rate have on accuracy?? Also what would people recommend a .204 or .223 given that I am only going to be starting home loading this year?!
Cheers in advance guys
