[QUOTE="Darryl Cassel, post: 987, member: 34"] Boyd With long barrels (Saeed is testing NORMAL length barrels of 26") such as my 37" chambered in the 30/378 I have taken the 200 grain to 3550 FPS without ANY problem. The 220 I could push to 3350 and 3400 without problems. Now this was with a large Custom action and 115 to 117 Grs of powder. There are no 300 RUMs that will achieve this as to date. Mainly because the standard mag factory actions won't be safe under these pressures. I am testing the 300 Tomahawk to 100 grs of powder (so far) using 190, 200, 220 and 240 Gr bullets. I will let you know the outcome. I have been known to push the envelope when testing powder, case and bullets. I could get some unbelievable velocity in the case I designed many years ago. It was based on the 8MM mag and blown out to the minimum tapor and had a 40 degree Ackley shoulder. It was called the "308 DC Super IMP." It was about .002" larger at the shoulder diameter then the Baer case (Before I knew of the Bear case) and a bit longer because I used the 8MM mag case instead of the 300 Weatheby as my base design. I could shoot in excess of 100 grs of ball powder in it and with 190 and 200 gr Match Kings, I could almost duplicate the 30/378. Not quite, but within 150 FPS with the 200 gr bullet. My thoughts at the time were, why go to the BIG custom actions if I can get that close with a smaller 30Cal? My case had a water capacity of 106 Grs as compared to the 300 RUM of 112 grs. That rifle is owned by a good friend of mine in Midland, PA. I do have two more of them sitting here. Several shooter/hunters have chambered that cartridge for their hunting rifles. The reamer can be found at Clymer reamers where it is on file. Problem is, you have to fire form and fool around a bit with it but, it sure is an impressive case when all is said and done. It Can be shot on a Standard Mag factory action also. So far, from what I'm seeing, My case or the Baer case would be every bit as good as the 300 RUM if you had the barrel length to burn all the powder. I am going to compare them side by side and make my final decision as to my findings. I have never made statements pertaining to any caliber, chambering, bullets, actions, barrels, scopes, stocks, triggers, etc, until I tried it first. If someone said this caliber is the best thing since sliced bread, I would chamber it and just see how good it is. I have had most every longrange caliber and can give a good comparison to any.
