I have a good 100m load for my 308 Sauer (Hornady 150grn I/L, 44.5grn N140, loaded to cannelure and finished in a Lee collect crimp die) which will clover leaf if I do my bit.
I have shot it out to 200m but not approached this scientifically - chrono, tweak the powder, change the OAL.
I plan to do this in the Spring and would like to understand are there any parameters that would help develop the consistency of the round beyond 100m.
I also have an excellent load with Nosler BTs which do allow me to play with OAL. I don't see changing OAL as a real option with cannelure heads.
Bound to be a trade off - just wandering what experience others have.
