[QUOTE="LRHWAL, post: 161128, member: 5418"] I was provided with data by Walt Berger within a day or so of dropping Berger's helpline an e-mail on the website The data as developed on quick load and for a 26" barrel with H1000 was: 72.5 gr - 2689fps 76.2 - 2836 fps (maximum load). I suggest you get in touch with them directly, and certainly I don't accept responsibility for this data. In short - that says your load may be too high. Certainly your cases are telling you that. We often don't know "why". I'm sometimes surprised by the numbers some guys get and claim are not "over pressure" when we have no real way to measure. I use a chronograph and if I get more velocity than I figure I should I accept that it's probably over pressure. I don't question that you get "fast barrels" and diameter differences that can affect this, but that's how I would see it. With South African powders 210 Bergers at 2850 in my 300WM (26") are where I'm comfortable and 2900 was pushing it. I often wonder if the 50 or 100 fps really makes any appreciable difference and why we "chase it" (not saying you are, just commenting). I we really NEED more speed we should buy bigger guns. I fall into this from time to time - not saying I'm immune, but I'm having a lucid moment, so commenting on it. I hope that data helps some. I've got it for other US powders too if need be, but as Eric said - go to Berger's site directly and they'll hook you up with data. Wim (SA) [/QUOTE]
