For the past few years, I haven't shot my 45-70 Farmingdale Business Rifle much. It's got a heavy 28" round barrel and shoots like a dream. In order to adjust the vernier tang sight, I'd have to remove my muffs, take off my shooting glasses, put on my reading glasses, make the adjustment and reverse the process .... enough of a PITA to discourage me from shooting it.
Recently I had my eyes tested and was told that I now had a slight long range prescription. The solution was progressive lenses! Now I can read the 1/4 minute increments on the sight ladder, make the adjustments and carry on with shooting in seconds. Yee-haw!
At the range yesterday, I was happily moving from the rams to the turkeys, to the 200 yd gong back to the rams and then the 300 yd gong ..... all my old sight settings were still valid.
I was sharing the range with a young fellow who had a brace of high tech .308 'tacticool' rifles. We were spotting for each other and were surprised that the x-wind affected his 155 gr Berger bullets as much as my 500 gr Lyman 457125s. I was holding on the head of the rams to hit them in the butt and so was he.
He also had a stock GI Remington '17 in .30-'06 and it shot as well as the scoped .308s right out to the rams.
