Hey new to the board and trying to get an idea of the best way to go on a new long range rifle, for target, varmint and possible hunting. Currently looking at 7mm WSM, 7mm rem mag, or 300 wsm or 300 win mag. Looking at starting with a Lawton 7000 or 7500 action or Shilen custom action and sendero style barrell-26". Not sure if I will use my ginsmith or have lawton machine or Shilen build it. Any input I like the ballistics on the 7mm but not sure how they compare ballistically out past 500 yards. I think I prefer the WSM to the rem mag.
