When my oldest began hunting (he's 49 now), I started him off with a 308 wearing a 2.5X Tasco with a 32 mm objective. I don't know how long I'd had it but I it wasn't bought new, must have been on a rifle I bought/traded for. Anyway, I wanted a fixed power so he wouldn't be fiddling with it and I wanted enuf objective that it would gather light. That old Tasco worked well for him and for both of my other kids when their time came. About 5-6 years ago I had it on a rifle and it quit tracking. I gave it to a kid as a toy at a gun show. Over the years it must have gone on and off of close to 10 different rifles from 223 up to 45-70, and worked perfectly up til it died. I wish I had another one just like it to put on the Marlin 1895 I have now....
