2 Newby questions on load development with a 6BR for F-Class competition

[foxx]

I am also just getting started with a 6BR. It's a fine cartridge ad a joy to shoot.
There's a lot of good info on 6BR here:http://www.accurateshooter.com/cartridge-guides/6mmbr/

To answer #2 Try jamming. Reports are that it helps. I don't really care why. :) Depending on your neck tension, the rifling might push the bullet into the case, but to test it, chamber a round, then remove it and measure from the ogive. Maybe it will, maybe it won't. If it does, it still might shoot well that way, you gotta test it and see. Only issue might be that the bullet might stick in the lands when trying to remove the round from the chamber, so have a cleaning rod and brush available to clean out spilled powder from the chamber. Also, you MIGHT be able to run a dowel down the barrel and compare it's length against the tip of a chambered bullet seated short of the lands with one you intended to seat deeper into the lands. (that way you don't have to remove the chambered rounds, risking separation and subsequent powder spill.) Might want to do this will a "dummy" round. :)

My guess is it will seat the bullet into the case more. If so, it may very well like it that way. Based on reports that jamming into the lands is better, you may want to add neck tension to some of them and see if it likes being jammed. Point being, it is not dangerous to do so and you'll never know till you try it.
