Any 1st hand experience (or 3rd party documented) comparing the .338 Lapua Mag 300gr Berger Hybrid and the 300gr SMK's? Am seeing some crazy long shots on Youtube with the Bergers that I thought were beyond the max supersonic range for 338LM. Not too interested in having a bullet that I could hunt with and use for target, but if the Berger extends the supersonic range of 338LM well beyond 1700 meters that I associate with the 300gr SMK's then they may be worth the extra $. Also, I don't mind having to single load if the COAL is greater than my box mag capacity. Thanks in advance!
