55 GR Nosler BT in the 6BR

[NCVarhtr]

I have a couple of thousand 55 Gr Nosler BT that I would like to shoot in one of my 6BR rifles with zero freebore. Probably use H-322...I'm wondering what your experience has been with seating depth? Even with zero freebore, there is very little bullet in the case neck when seated up close to the lands. I know every rifle is a little different, but I was hoping to get some ideas from some of you guys that have used that bullet and what kind of jump you have found that works well....Thanks for any thoughts, ideas or experience.....George

I think we are in the same boat.

I haven't had time to load them, have not measured my throat/distance to lands.

Mine has 0 freebore. A 55BT seats exactly halfway down the neck when touching the lands. Best powder I've used in that cartridge is AA2230. The accuracy window in a BR is very wide. My best 55/58gr loads - accuracy/velocity - are 3850 to 3900 with AA2230 powder and either 7-1/2 or BR4 primer.
