Looking at doing something in 6.5mm with a 6.5 BR. The first question is what bullet weight and companion twist rate are candidates for 100/200-yard bench rest shooting? Converting 6.5mm to inches we get 0.2556...
The other question is which mould? Saeco has a 140-grain mold. Accurate doesn't go that “small". However, NOE has quite a selection of diameters, 258-260", ranging between 80 and 120-grains. NEI has a few offerings but not many, (8) bullets in 0.257", 65-110-grains.
LBT has 0.257” dia. bullets ranging from 90-117-grains. But Veral made a .30-caliber mould for me that I've been using for over 10-years that shoots very well, so maybe a 6.5 version of that design?
Thanks for any feedback!
