[QUOTE="J E Custom, post: 540551, member: 2736"] Very good comments ,and very true In my opinion. One of the first things I look at when trying to decide on a cartrige after deciding use and distance,is case density. I want the max velocity,(For energy and trajectory) with 100% case density using the optimum bullet weight for the cartrige selected. With the 338 RCM the 180 grain bullet produces=3647 ft/lbs of energy @ 2980 ft/sec velocity. The 200 grain bullet produces = 3864 ft/lbs of energy @2950 ft/sec velocity. And the 225 grain bullet produces=3778 ft/lbs of energy@2750 ft/sec vel. These are 100% powder density,Max loads for each bullet and in a compact rifle a bigger/heavy bullet would only increase BCs so the 200 grain was chosen for a max distance of 675 yards for 1500 ft/lbs of energy at the POI for ELK. If I were going bear Hunting I would probably choose the 225 grain bullet and limit distance to under 400 yards. There are so many great 338s that will shoot the 250 and 300 grain bullets for 1000+yards I felt there was no need to increase case capacity or improve the case based on its use and as is potential. It is a special purpose rifle, just like most of the long range rifles that are intended to shoot well beyond 1000 yards. As said earlier it is a compact cartrige that is equal to a 338 Win Mag, and we all know what it can do. I would not hesitate to carry it in Alaska or any other place knowing what its capabilities are. I appreciate all comments from all on this site and feel better about my choice after hearing them,And best of all Its Fun to shoot. J E CUSTOM [/QUOTE]
