RE: 243 or 223
I have a .243 Savage Model 10 - I love it for yotes. Never had too much problem with pelt damage - i found that if I used a heavier load the bullet holds together better and passes through the animal with minimal damage and with lighter loads the expanded quicker and created a larger exit hole than I was happy with.
I have used remington 100 Grain CoreLocks with great success.
