I have a savage 11vt in 308 and sierra matchking 175gr bullets. I'm still trying to find powder but will hopefully get IMR 1460 or varget. I bought a modified casing to measure how far forward the bullet would be seated to be against the lands and grooves in my chamber/barrel. My question is: should I seat it to the Max length or slightly deeper? How much deeper?

Also, should I crimp at all?

Thanks!
