I've decided that life would be much more complete with a fast 7mm and have it down to 3 options after reading too many threads on here. Basically looking for a 160 at around 3100 but wouldn't be disappointed if velocity was slightly less. Input on which way you would go is greatly appreciated...

1)long throating a 7mm rem mag. Figure that if I keep over all length around 3.3 I should see some of the benefits of the weatherby with cheaper brass costs and be able to shoot factory ammo in a pinch.

2) 7mm weatherby, only down side is higher cost of brass and scarce factory ammo around here.

3) the mashburn. If i use a form/trim die is fire forming still necessary for full power loads? Also, I would like to have headstamped brass when possible if i travel to hunt. I've saw where quality cart. sells it but have heard differing things about the quality.
