I've won all my Service Rifle and Sniper rifle medals with the Hornady Custom grade dies. There... does that help? Then again, I 've had great sniper partners who really help me with the wind....
Seriously now... I love the Hornady dies. I had all RCBS dies about 20 years ago. Then I found that Hornady had a 'micro adjust' bullet seating device that allowed you to 'dial' in your different bullet lengths. Great for my needs of a .223 inventory of different bullets.
I shoot with a .223 for Service Rifle (68 gr. & 69 gr.), Tac Carbine (62 gr. & 55 gr. FMJ), Precision Rifle (75 gr. AMAX) ... Now you can see why I like being able to dial in my bullet lengths.
I also happen to be a cheap bastard (okay, I do know who my father is..) but I am cheap according to my sons. With that context, I like to keep my die sets the same, spare parts and all that jazz. I like the decapping rods in the Hornady. I have broken very few of the decapping pins, unlike with my previous RCBS inventory of dies, I was always bending or busting decapping pins.
Hope this helps,
Barney
