I have seen a short 7mm carbon wrap barrel for sale at a very good price. So it's got me thinking about wether it's worth buying and holding on to for a future build... (like I really need another rifle ) The barrel will finish around 17 inches. It will be used for deer and varmints max 400m. 7-08 is an obvious choice but what else would work well in peoples experience? Also what bullet would you guys use for said caliber?
