If this is the case, why not zero for 200? Shoot it for dope at 300 and be well inside a more ethical mpbr for the rifle.How true, though most of what you say applies to any hunting regardless of zero. I agree there are a lot of hunters that take shots they shouldn't or aren't capable of ensuring a clean kill.
In my case this particular rifle does shoot 3" groups at 300 yards with this load. I doubt I would take a 300 yard shot at a deer. Have only taken 1 at 200 yards. Otherwise 25-135.
Thanks for sharing your wisdom.
