[QUOTE="jarnold37, post: 2125611, member: 29241"] I have been fortunate for the last 35 years to have had the opportunity to deer hunt on our farm. Hay fields with partially grown up pasture with shots maximum distance of 1000 yards with most shots 250-600 yards. Also I am fortunate to fit and chamber rifles myself, which allowed me to try different cartridges and different bullets. I have learned that sectional density may be more important than ballistic coefficient. That is not so much as how well the bullet cuts through the air, but the relationship of the length to the diameter. It basically applies to every caliber. Have used 30-378 with 180 grain and can achieve 3475 fps. Hunting also with 338 weatherby and 338 RUM propels the 180 grain 3725 fps, with much more "smackability" as even though bullet weight is the same the bigger neck opening allows for more velocity and also it sectional density is less which allows to expend its energy all at once as opposed to the 30 caliber 180 having a higher sectional density which has allowed pass throughs. Shot one deer at 190 yards and the 180 passed through and killed 2nd deer standing behind it dropping it but 1st deer ran 150 yards. The 338 180 grain is much more effective. To achieve similar results in the 30 caliber I went to 125 grain bullet at 4050 fps. I almost ordered a reamer for 378 weatherby (RUM provides same velocities) and have read it is a very good cartridge. May still try it. [/QUOTE]
