I used a Tasco PDP3 red dot on my 14" Contender .375 Winchester barrel for a couple of years, then switched to a bushnell scope...the red dot held up just fine on the several hundred shots I fired a year...never had problems with it hunting either, but wanted some magnification for longer shots, so I switched to the Bushnell scope. The Tasco now sits on a Ruger GP100 .357 Mag. and does a great job there as well. I was scared, from what I had heard, about the life of red dots and the big kickers, but like I said, no problems and that was hundreds of shots.
