[QUOTE="jmden, post: 156154, member: 1742"] [b]Re: Heavy hunting bullet for 10 twist, 26\", 300RUM?[/b] I just had a pleasant conversation with Richard Graves of Wildcat Bullets and got some answers to my questions. I was struck by his willingness to spend some of the little time he has on a complete stranger--very much appreciated. He doesn't have the 'old' (non-Al tipped) style .308 225g WC's 'in stock' at the moment and it sounds like he's putting most of his bullet making energy into the Al tipped bullets. He's apparently had some jacket issues and is working through that with available manufactureres--each manufacturer and jacket comes with it's own set of compromises. One manufacturer's jackets are heavier and might make a good hunting bullet (from close in to out quite a ways) in combo with the Al tip, but may not be quite as good a quality jacket--those kinds of issues. A couple of numbers: 1. old style 225WC-10 twist (300RUM velocities)--on edge of stabilizing 2. new Al 215g-9 twist most likely (1.830" bullet length) 3. new Al 225g-8 twist most likely (nearly 2" bullet length) 4. may have a new Al 210g in a month or so (said to call back then) that should stabilize in a 10 twist However, with the current construction of these bullets, they are not meant for the elk you see at 20 yds. That Al tip will expand 'em pretty fast at that range as we've been hearing. Solutions are to bond or go with heavier jackets as mentioned above. The bonding would make the bullets pretty spendy...but what a combination of BC and hard hitting, huh? Hope this helps somebody. If I screwed any of this up, please correct me Mr. Graves. Thanks all.
