2 questions if anyone has a minute to give me some first hand feedback... 1. I inherited an old Winchester 30-30 model 94 from my grandfather. Operates and fires perfectly. Hooded front site; patridge rear site. Sentimentally I hesitate to change anything about it but i have terrible eyesight as it is.What recommendations would you make for upgrading the rear site without dratically changing the look gun? 2. Just bought a savage 220. I have my own ideas for a scope but want to know what y'all out there are using and how you like it. Thank you much!
