Also in the f class word ie FT-O hardly anyone uses a 6mm. Vast majority use either the 284 or 7 prcw. 6mm are great for not so windy days. Also FT-R majority of shooters using 308’s are shooting bergers 200.20 others still use 185 juggernauts.
And hardly anybody uses a .308 Winchester in F-Open. What's your point?
Why do people shoot the 200.20X? The reason I shoot it is because it has the highest BC I can get and stay within the rules of the game. The BC gives it an advantage over the 155s, 168s, 175s, etc. That means less error with wind changes.
