First of all What is the twist? This round was (in the past ) sometimes twisted rather slow for a 6.5 mm. It may not stabilize the 140s???? One turn in 9 inches will work if it is a 10 inch or slower????????????
Many of the data sources will give only a few loads and then say that 264 win mag data can be used. There are some loads on Accurate reloading"s site
