I just picked up a new 6.5 Grendel. A Howa Mini action bolt gun. I am begining to work up loads and have found that my new gun has a generous amount of headspace. I base this on the fact that the case grew .0055 using my Hornady headspace gauge. I only want to bump the shoulder back .001-.002. I like to work the brass as little as possible.
What do you guys do to limit bumping the shoulder all the way back? I know I should get a set of competition shell holders but thought I would ask in case i am overlooking something.
Thanks

Andy, another option is to take your headspace gauge, with calipers and zero it out on a fired piece of brass. Set your sizing for high and slowly crank it down. After each stroke recheck the headspace. Repeat until you reach the desired shoulder set back. I primarily neck size but there comes a point in time when the shoulder needs a bump and that’s my method.

Basically not letting the sizing die completely size the brass but rather just enough to get my shoulder set back to where I want?

Correct. It is possible to bump the shoulder and not work the entire case with a F/L die.

Your cases won’t be fully fire formed, (which is what you want) after one firing though. Can you close the bolt relatively easily on your fired cases now?

Back the sizing die out . When you get the die where you want it , set the lock rings . Might involve a little trial and error but nothing is complicated about this method .
