For those that test tons of bullets - what’s the easiest 6.5 bullet to develop a load for?
I have to go with the 129 Interlock, also. My Criterion barrels shoot these well with any load, but I have yet to find
a rifle in ANY caliber that does not like Interlocks. I have shot around 200 deer with Interlocks in 6mm and 6.5mm, and a few with .308 and 30-06 and they are super accurate and kill deer just fine.
