Seems its about 50/50 on doing development on virgin brass or not.
So for the guys that don't, WTF are you doing to get the brass once fired? I hate wasting rounds/componants on bullshit, but do you just sight the gun in and shoot all the brass once for the hell of it and then start the development?
Depends on how much brass you have, or how much you plan on shooting the gun I’d say.
On my 338L
I ran 100 cases thru the gun doing fire forming
First though,
All cases ran thru Sinclair carbide mandrel die
I Check with pin Hole gauges to inspect how tight the necks are and aim for (-.002 to caliber)
Chamfer inside primer pockets
Check brass length to reamer specs
Chamfer inside and outside of necks
Load up and go from here
My process is
All shots are done with a Lab/Radar and documented even with barrel break-in
Barrel break in 10-15 shots
Powder adjustments 25 shots
Bullet seating depth test 25 shots
300 yard powder adjustment 25 shots
(I’d of choose a longer range if I had a place to shoot out that far)
By doing this I was able to go thru what was the best and basically
Had all brass ready for fine tuning!
After all brass was now shot
Fine tune Powder, Primers, and bullet seating depth again now it’s done
Not saying it’s the right way! But it’s what works for me…
