I too use the Ultra-Dot ( lifetime warranty )and Burris Fastfires ( Burris is much smaller ), and 180 grain slugs. I use and have great luck with the Remington 180 jhp. Can buy them in bulk and they work great on deer sized game and smaller. I've used them in 357 Mag, 357 Max, and 357 Bain & Davis. Also good luck with cast 180 grain swc.
