As typical of me, spent this morning at range with 5 rifles. One was a Marlin XT22 with a Simmons Pro Hunter 6-18x40 side focus scope. Own at least 3 of the Pro-Hunter scopes with rest on mid recoiling centerfire rifles such as the 257Roberts I was also shooting today. Decent scopes for my paper shooting. Being a 40mm lens, the 6-18 power is not a bad fit on a 22 rifle. Crosshairs could be finer, but they're acceptable for my usual 50 yd 22 LR target shooting.
Mind you, most of the Simmons Pro Hunter models were discontinued when Bushnell acquired Simmons. All of mine are the Meade made Simmons Pro Hunters. At www.natchezss.com
you can find the discontined 6-18x40 SF for $70 plus shipping. Worth a look. By the way, gent on Rimfire Central posted about the scope a couple of months ago and how happy/impressed he was with it.
