just had a stiller predator action barrelled in 6.5x284.with 24 " kriegar barrel 1/8 twist.
have some bergar 140gr vld. but because of barrel life dont want to waste 100s of rounds looking for load..
most of the data you find is for 26-28"barrels .dont know what realistic velocitys wil be and what powder to start with.
greatful for any advice
