Hello! been awhile since I posted any way, I'm 53 with early stage cataracs, diabetes, and progressing Glaucoma among many other medical conditions too many to list. most, of my shooting any more is at 50yds. and target only, due to lower back, both knees, and heart and lung conditions etc. so, hunting period is out of the question for me any more. but, I'm going to continue to shoot till the Glaucoma tells me it's totally useless or dangerous.
