I have been shooting and longer ranges for a couple years now, and have started to consider using this skill to harvest game. While most of my hunts involve walking through thick western WA forest, there is great areas for longer shots. All that being said, my standard prone or rested distance, weather off a stump or pack is around 800 yards. I have the necessary data and tools to read wind and make adjustments using a ballistic calculator. But I wonder if I have the right caliber for the job, I have three options. A 7wsm a 7mag and a 300wsm, I also have a 6.5x47 lapua but I think it may be small for big game hunting at longer ranges. What do those of you with experience feel is the best option and what is a realistic range? I prefer to target vitals, high shoulder shots are not my style, bullets used are as follows- 300wsm 185or210vld hunting, 7wsm 139gr Sst, 7mag 168gr vld hunting, all rifles shoot sub moa with the 300 being the best. Thanks for any help, this site is an awesome resource for guys like me just starting out!
