[QUOTE="del2les, post: 1733332, member: 9299"] For several of us, we do use a variety of 243, 243AI, 6mm and 6mmAI for LR on 600 and 1,000yd BR, deer, antelope and varmints. Proper twist is required for high BC bullets, but I have used 1/9's with good success up to the 105's. When I rebarrel either, I will go with a 1/8tw for the longer bullets and better LR stability. I have an older 6mm M700 Varmint in a 1/9 twist that still shoots the 105 AMAX into sub 1/2 MOA groups, but those are handloads and most factory stuff isn't up to snuff for LR shooting. My 243 and 6mmAI targets wear 26" tubes and 1/9 twists and they shoot very well with a variety of bullets. Historically, factory ammo for either was not up to snuff for LR shooting, barrel twists in 243 were 1/10 and too slow for high BC bullets, so custom barrels, faster twists and handloading were requirements for these 2. However, when done correctly, the varied 6mm calibers are good performers at extended ranges. [/QUOTE]
