I knew that I didn't see my sights real clear and my hands aren't as steady as they once where hell, I'll be 79 nest month. Today I put on my 1.5 reading glasses from Menards hardware and the sights cleared right up. I use a 6x6 swing plate at 25 yards, now I know some of you young bucks laugh at such a large target but it works for me. I loaded some of my favorite 150 grain 358477 bullets over 6 grains Unique in .38 Special cases in my 4" 686 Smith and when the plate swung 4 times out of 4 shots I grinned and came home. I know many wouldn't consider that much of a shot but for this old codger it sure looked good.
