As to recoil, I suffered a PVD(posterior vitreous detachment) about 7 months ago. That is were we get vision ," floaters" as we age. The fluid in our eyes develops a ,"skin" , on the interior surface of our eyes. A PVD is caused by the skin pulling away from the surface of the eye.

I was unlucky, mine stuck dead center of my retina. OK at bedtime, legally blind in my left eye when I woke up the next morning. After several months it finally pulled free, tearing my retina in several places.

After a few laser surgeries to seal the holes my doc said I could resume normal activities, ya right! it was my dominate eye.

He did tell me no more heavy recoil shooting. My doc also told me not to shoot any heavy recoiling hand guns either.

He said that the recoil can create an impact all the way up the arms, shoulders and neck causing shock to the retina.

When I asked how much he said lay off the .44mag and the 300gr. long Colts for at least a year.
