[QUOTE="VinceMule, post: 2446492, member: 122164"] 6.5x47 Lapua with 147g eldm (.697 BC) is tough to beat in accuracy and long barrel life. I am using AA4350 with Rem 7 1/2"s. If you are building a long range varmint rifle, you want long barrel life with some wind bucking ability. Barrel life on the combo above is around 2800 rounds perhaps more if you do not over heat the barrel. AA2700 will extend the barrel life even more, I am working on loads for this combo now. If you can stand the weight, a 30-31" finished barrel in a 5R configuration will get you 2800 fps with the 147's using only a smidgeon of powder. If you were to go 260 AI or 6.5/284, then the barrel life will be 1200 rounds or less, but you could push it further with some flyers from time to time. The 147's do not react well with a rough barrel. [/QUOTE]
