[QUOTE="Fiftydriver, post: 131463, member: 10"] JDJones, Thats not a very good attitude to take on a big 30 cal!!! [img]/ubbthreads/images/graemlins/grin.gif[/img] Overbore, come on now, I have been hearing this the entire time I have been playing with the Allen Magnums. The key to using these very large cases efficently is to use an extremely heavy bullet for caliber. Take my 257 Allen Mag for instance, many would correctly say that with conventional bullets, 95 to 100 gr capacities are just to much for this bore diameter. That is true when dealing with bullets in the 85 to 120 gr range. Drop in a 156 gr ULD RBBT and its a totally differnt story!! I have three designs for the 300 Allen Magnum. All are the same basic design, only difference is length of the body. There are three lengths, 2.700" case length, 2.850" and full length 3.050" case length. The shortest length would have a capacity about 15 grains more then a 30-378 Wby. I am going to start with the full length version first and see what happens. Please realize that I do not see the 300 Allen Magnum practical for any bullet under 250 gr in 30 cal. Just like my 338 AM and my opinion there is no reason to shoot anything under 300 gr in that chambering. Better yet in the 300 Allen Mag will be the new 265 gr ULD RBBT, 290 gr ULD RBBT and even the 300 gr ULD RBBT if Richard releases one. If someone wants to shoot a 180 to 200 gr bullet then they might as well just order the Xpress or a RUM or 30-378 because it will be a waste of time with the big Allen Mag. As far as the 180 and 200 gr pills go, they would perfectly at home in a 1-10 twist 300 Allen Xpress. TO that point, if you use a 180 gr or 200 gr Accubond, they will handle anything you can throw at them down to a 1-8 twist barrel. Come on, don;t we need a 145 gr powder capacity 30 cal magnum!!!
