[QUOTE="Long Time Long Ranger, post: 501164, member: 505"] My 338 Lapua that gets the most hunting is a lightweight carry rifle with a 26" barrel. It is excellent as a light carry rifle for any game. To reduce recoil in the light rifle and make it more pleasant for my wife to shoot I have loaded the 225 accubond in it for the past few years. It will easily take any game to 1000 yards. My wife took her monster muley with it this year at 516 yards and just destroyed it. My best accuracy load for it is 3320 fps and I can do that with three different powders. Best accuracy load with a 300 grain bullet is just over 2800 fps. Comparing the 225 at 3320 and the 300 at 2820 at 5000 feet elevation and a zero of 2.5" high at 100 yards the 225 shoots 43" flatter at 900 yards with 6" more wind drift. At 1000 yards the 225 shoots 53" flatter with 7" more wind drift. Not enough wind drift to make a difference but the flatter trajectory makes quite a difference shooting mil dots. If anyone plans on shooting beyond 1000 yards with the Lapua it is best to go with the highest BC's and not the 225 although the 225 will easily kill game at 1200 yards out of the Lapua. With this class of cartridge I am going to try the cutting edge 225 grain bc .640 and 250 grain bc .720 in the future. That 252 with a .720 bc will greatly extend the range of the lapua and RUM's. I can push the 250 SMK at 3140 fps out of my lapua. If the cutting edge bullets work out they could be special at the ranges most anyone could ever kill an animal. With heavy rifles that can tame the recoil of the 300 grainers they are fun to shoot. But the recoil difference in a light carry rifle is tremendous going to the 300 grainers from say a 225 grain. Recoil is accuracy for most people. As recoil goes up, accuracy goes down. That is fact. The 225 accubond has better on game performance than the 300 SMK. I forgot to put the other data in here. Again same 5000 feet elevation and 2.5" high zero at 100 yards. At 800 yards the 225 accubond is in the 15" elk kill zone for 47 yards vs 36 yards for the 300 SMK. The 300 SMK has 4" less wind drift. At 1000 yards the 225 accubond is in the 15" kill zone for 31 yards vs. the 300 SMK in the kill zone for 25 yards. The 300 SMK has 7" less wind drift. So I get 11 more yards in the kill zone with the 225 accubond and 4" more wind drift at 800 yards. Or nearly a 25% better chance in the kill zone with only 4" wind difference in a 10 mph wind. Less recoil and a premium hunting bullet. As I stated earlier if your shooting over 1000 yards the 300 grainers look better the further out you go. [/QUOTE]
