guys, what's the effective range of 3" magnum OO Buckshot 15 pellets? I shot a yote in my back yard last night @ about 50-60 yards, got another off at 70 and one @ 90. I found some hair at 50-60 yards. Just wondering if it had enough umfff to penetrate good.

what do you guys think the effective range is? it's a 12ga. 28" barrel w/ mod choke.

thanks,
Dave
