[QUOTE="Mysticplayer, post: 3801, member: 8947"] Those are really big cases for that bullet weight. I guess you have a big need for speed. How far are you planning on hunting with this rig? If this is the only bullet weight you are going to use, 1 in 12 twist will be plenty. I would suggest you look up data on cases like the RUM/reg 300Wby and compare to the Lazz and Wby. Chances are they is not that much difference in vel. This is simply due to the overbore nature of these big cases. They are even less effective when launching "lighter" bullets. Balancing max. vel and accuracy may also be a little touchy with these cases. What powders are you planning on using? Keep an eye on the throating too. Try and keep the throat short enough so that the bullets can be on or just off the lands and feed from your mag. The WBY freebore can make it more difficult to get an accurate rifle. If nothing else, this rig should get some very high muzzle vel and shoot plenty flat. Sort of like 40gr Vmax in a 22/250. Enjoy... Jerry [/QUOTE]
