[QUOTE="trueblue, post: 424978, member: 10654"] There seams to be a trade off to be reached with these longrange carry rifles between weight, fps, downrange energy, ect. On one hand you need a big case like the 338 Cheytac to have 1500# of energy at a mile, but the weight of the rifle is to heavy to carry on your back all day long. The lighter builds like the 338 Norma/Lapua/EDGE can be done in 12 1/2# all up, but does not carry the payload of 1500# at a mile. Then you need to also think about the wind advantage of each cartridge. Between the 300gr SMK going 2750fps vs. 2950fps there is only 14" less wind @ 1500 yards from the faster case. That is only an improvement of 10%. So it seems you would need to jump up to the Cheytac case to get a real advantage in wind trajectory of say 20-25% with the 300gr SMK going 3200fps. The other issue is recoil. Shooting the 300gr SMK faster is going to generate more recoil and be felt more in a lighter rifle, and be harder to shoot accurately in a lighter rifle. So, where is a good balance of all this between energy, recoil, rifle weight, and wind trajectory? [/QUOTE]
