[QUOTE="azsugarbear, post: 687661, member: 4809"] Not exactly sure what you found contradictory about the statement, but perhaps I should have gone further with the thought process. First of all, whether we are talking about the the 338 RUM, 338 Edge, or 338 Lapua - they all are ballistically pretty close to each other. So let's use the 338 Lapua to compare to the 300 RUM. Let's use the following as examples: 240 SMK @ 2,750 fps 230 OTM @ 2,800 fps 210 VLD @ 2,950 fps 200 AB @ 3,015 fps The end result at 1,000 yds for each of the loads is anywhere from 20.5 to 23.5 MOA dial up for elevation. The hold-off for a 10 mph crosswind is either 5.25 to 5.5 MOA depending on the example used. Foot pounds of energy delivered at 1,000 yds ranges from approx. 1,250 ft/lbs for the 200 gr AB on up to 1,500ft/lbs for the 240 SMK. The lapua loaded with a 300 gr OTM @2,750 fps requires 21.5 MOA dial up for elevation. With the same wind conditions, hold-off is about 4.5 MOA. These numbers are pretty much in line with the ballistics of the 300 RUM loads. No real advantage that I can see. Now when it comes to energy delivered, there is a real difference with the 338 Lapua delivering an est. 2,175 ft/lbs. There has been a long-standing consensus in hunting/shooting circles that a minimum of 1,000 ft/lbs is necessary to kill an elk cleanly. It can be done with less, but for the average shooter, 1,000 ft./lbs is a good rule of thumb. With that in mind, any of the 300 RUM loads along with the 338 Lapua load, deliver substantially more energy than what is required. That's why I noted the ft/lbs delivered by the 338 Lapua as an exception. So, from a ballistics point of view, the 300 RUM can pretty much do what the big 338's do. Additional energy is always nice - providing you can manage the recoil, but dead is still dead. [/QUOTE]
