You're talking about my most favorable gun in my safe.

I have a 12 Gauge H&R Ultra Slug and have never missed with this gun to date. Knock on wood.

Here is what I have done to be successful hunting in an area that allows for long range shots.

Sighting In:
I sighted my H&R in with zero wind in a vice for 3 inches high at 100 yards

At 150 yards my gun is zero -I aim dead onand am very lethal at this range.

Ammo:
I use Hornady SST's going 2000 fps with 6.5 inch drop at 200 yards.

A must have for long range shots:
I use a Nikon Range Finder. I need the range finder for shots past 150 yards when my bullet is decending. It's like throwing a baseball. Understand this gun and how it acts and you will harvest ever animal that walks in your path. It's all about confidence.

DO NOT
Do not go cheap on a scope for this gun. The H&R Ultra Slug wants you to push it to the limit. I'm running a 2X7 Leopold on mine. I want a 3X9 for it but I'm afraid to move anything.

Here is a group at 100 yards with my H&R. I took a doe at 218 yards this year with mine. Nikon Range Finder and placed the cross hairs on the spine with low wind conditions. Good Luck!!
