Thread: Q1 COAL ...a novice reloader question.

Don't do it. COAL isn't what you're after. It's the ogive length as in some bullets you'll find variances in length going from tip to base. The ogive stays the same and it's that distance to the lands you want. You'll need something like the hornady comparator tool and a modified case etc to do it properly.(you can make your own) At the vary least pull a bullet just slightly neck size a fired case( with no powder, primer) so it only holds the bullet lightly and close the bolt on it a few times repeating the process. This should give you the just touch length then back off 10"min, but isn't as accurate and if the bullet sticks a fraction in the rifling will give you a false reading. It works but has it's prickles if not done properly. I almost got caught using the right gear yesterday. I couldn't get the right jump, head space either. I thought it was a die problem but then find I have a slightly over length chamber. Not a problem in its self but what I didn't notice was new brass and a different caliber that my primer tool was leaving the primers a couple of thou proud in the the cases. Doesn't do it with any other and now adjusted all is good. Luckily I noticed the vernier rocking when I was measuring. If you're going to do it get the right gear and do it properly or you could be heading for a nasty surprise. Not all factory ammo is loaded down and not all guns shoot the same. A bullet jammed into the lands won't be a fun experience with a hot load behind it. If you do decide to have a go then take your time and check then check and finally check again. As above I would't bother , I'd just reload to what I wanted. Good luck
