Re: Custom turrets?
I'm sure the OP is thinking of Kenton Industries. I have used their products in the past on other people's rifles and they work "okay" as long as you know the limitations.
If you give them specs on x-round, at y-velocity, with z-zero, and all the other "variables" that they require, that is exactly what you get...a turret build with EXACTLY those variables. The problem is that with any "variables"...THEY F-ING VARY!! What you give them today to build you a custom BDC turret WILL be different every time you are at the range or in the field and every slight change in those variables will alter the trajectory of your bullet and the dope needed to accurately put shots on target. Some variations may be slight and you may still be able to put rounds on target, while others may be off by a mile (might as well be a mile...a miss is a miss).
Take 427's advice...more ammo and more range time.
