If I wanted to download the 416 to 375 DG performance levels, anyone have any ideas as to what is a reasonable benchmark? So the idea isn't necessarily to match 375 recoil levels, and definitely not to match say flat shooting plains game performance. The idea is more that given that the 375 is gauged as the lower, but effective range of DG rifle performance, what would a similar load in a 416 look like. For bear performance it is normally accepted that the 375 is all you would ever need, but I would feel even better about a 416 sized hole, and the upside is lower recoil and blast, with the ability to "take it to 11" if you need to. I am thinking of the 400 grain bullet. So I grabbed some quick load data which may serve as a starting point. The data suggested that factory specs are: 375 Ruger 300 grain, 2550 fps; 416 Ruger 2400 fps. On that basis, right or wrong, the 416 would need to have velocity reduced to 1726 fps in order to match the level of the 375 under the Taylor KO formula. That formula uses bullet diameter and weight and velocity, but not energy level. On energy alone the comparison would require a reduction to 2096. The average of the two formulas would come to 1911 fps. It would seem when comparing DG performance that the Taylor formula would be a reasonable reference. It does seem like a big velocity drop. I have to say when thinking with my shoulder, energy seems a pretty reasonable starting point, as it correlates to recoil velocity pretty well. However with the rifle one is getting hit by a "bullet" of the same diameter (recoil pad) and weight. Not one weighing 33% more and having a massive increased frontal area. Another way of looking at it would be to optimize the 416 for penetration comparable to the 375, but that really isn't as relevant on a bear, and it would probably virtually require full power loads? Any ideas?
