Re: 338 Rum
Angus, What powder you shooting in your sporterweight? With the old H1000 I could hit near 2800 fps out of my 26" barrel with the 300 smk but the accuracy was at around 2735 fps with 91 grains. I get good brass life with the lighter load. I use it for backpack hunting and under 1000 yards. Last summer I tested the 225 grain D 62 CE bullet .64 bc and the accuracy was best in the 3150-3200 fps range with much less recoil. When I ran the numbers for the range I use this gun the 225 with 400 extra fps looked pretty good. With a 225 grain bullet there is energy to spare so that is not a concern.
Predictions are difficult, especially when they involve the future
