I don't know about High Walls as I have not owned or shot one. I have handled C Sharps rifles and they are a well made rifle. That said, I own 2 - Shilohs and have had numerous calls to the company handled professionally and to my satisfaction. Shiloh is, IMHO, a very top-rate company. Shiloh also offers rifles for immediate sale (as does, I'm sure, C Sharps) on their website - rifles, for whatever reason, that were never actually purchased or issued. If you are a bit flexible in what you want in a rifle, you can have one in hand in less than a week. Most of the ones Shiloh has "in stock" are not really "dolled up" or of unusual caliber, so you may just see something you "need".

You'd have fun and be pleased with any of the ones you mentioned as well as the Winchester mentioned.

Someday I hope to be the person my dogs think I am . . .
The only true cost of having a dog is its death.

Shiloh Sharps . . . there is no substitute.
