I find myself highly concerned with optimal cartridges Feb-August. This is how I end up with a 280AI instead of a 280 or a 6.5x47 instead of a 7/08. Once hunting season comes around I could care less about 50 fps or .05 differences in BC. Off season boredom is also how I end up with 5000+ dollar scoped hunting rifles. My first deer rifle was an off the shelf 270 Win. My hunting successes or failures over the last 15 years would be no different if I had kept that rifle as my only rifle. This said, the 280 is way better than the 270 smile
