I looked at Foxhunter's picture of his chuck and got to wondering. Was the color right. Went out to shop where I have Vermont Woodchuck and Montana Yellow bellied Rock chuck mounts.
My Vermont chuck has similar color hair but no tinges of red hair around the leg like Foxhunters.
On the other hand the the Montana rock chuck is reddish without a doubt. Nothing like Foxhunter's chuck at all.
So what was catching my eye? Then I realized, I have that same tailgate on my truck.
That's the difference the size. My chuck is only 15 slots wide, Foxhunter's chuck is 17 slots long, two slots longer than mine. CTC on one slot is 1-1/4". My chuck was huge for a Rock chuck and weighed 17 lbs on a spring scale.
This thing Foxhunter shoot is a monster! Wow!
