[QUOTE=".300 Dakota, post: 1904502, member: 106514"] And I have a load for a 284 Winchester that averages 2945 f/s with 180 grain Bergers, but no way I'm about to throw that out there to somebody who owns an old Browning in that chambering and suggest they try it (or not even suggest anything). My rifle is specially built to handle this with a very long throat, and it is still "hot" because primers begin to flatten and ejector marks start to appear. I got burned on this once myself. I took data from a site that let members post data on a 6.5x284 Norma. I thought the numbers seemed gaudy, so I was smart enough to back off 1 grain from what the member published. It blew the primer out of the case and locked the bolt up on my Savage LRH! I don't know that I'd be here if I had used the entire charge. My chronograph registered over 3300 f/s with a Nosler 120gr Ballistic Tip. I do my fair share of wildcatting and load wildcatting to use powders not listed with cartridges by the manufacturer to find novel uses for which their burn rates are ideal. LeverEvolution is an example. LeverEvolution can be especially dangerous if the user is not knowledgeable. Likewise, I learned not to monkey with excessively fast burning powders for the Creedmoor loadings. There is a very narrow range of safety, and I found out as many years as I have found useful uncharted loads, I was in territory that I wasn't capable of controlling. Remember, it takes less of a fast burning powder to kill you than a slow one, but either will do the job when you reach that charge of 1 kernel above oblivion.
