I flat out need some advice from someone with experiance determining your optimum COAL.
I have measured the distance to the rifling in my Remington 700 VS-SF 223 at 2.244". (I cut a dummy cartridge from the mouth to the neck with a saw, deburred, started the bullet into the cartridge with finger pressure then chambered the cartridge. I took several readings and the 2.244" seems clear.
The factory ammo measures 2.20". Does this sound correct that the factory ammo could be less than 0.02" from the rifling? The reason I ask is that I bought used calipers, and now I'm wondering if they are accurate, or maybe I'm just confused.
When seating bullets for a particular rifle I have read that you should back off 0.02" in a few places and 0.002" elsewhere. If I backed off 0.02" it would put me shorter than a factory round. Or, is it in fact supposed to be only 0.002"?
As you might guess, I'm a reloading newbie
Here's what I am working with:
Remington 223 700 VS-SF
Lapua Brass
Sierra 52gr Matchking bullets
Thanks.
