I am wanting to get into F-class shooting, but having a hard time deciding on caliber. I have been a long time fan of 7mm and have been seriously considering the 7mm SAUM or WSM. However, If I can shoot a rifle with less recoil, I am a fan of that as well. I realy enjoyed George Gardners take on the .243 Winchester, which has sparked an interest. There are a lot of great 6 and 6.5 mm rounds out there. Can anyone offer any advice to what they think is best for F-class. Also, its a relatively new round, but does anybody have any experience with the 6.5 Creedmore?
