I have been loathe to post along these lines, but I hope to find better answers from the firearms community, and such is a necessity to receive a proper answer. I suffer from the long term effects of Retinopathy of Prematurity (google it), including poor sight at all ranges, gradual retinal degeneration of my peripheral vision, and the looming threat of an inevitable retinal detachment. I have heard tell of particularly vicious recoiling firearms leading to retinal detachment in individuals with issues similar to mine, and sought answers here. I've no desire for high recoiling long guns, but I do enjoy handguns. I've shot everything in a revolver up to full house .44 Magnum and snub .454 Casull; and every automatic service cartridge except .357 Sig and 10mm. I also run my 870 in 12ga readily with no noticeable issue except with repetitive rounds of buckshot (think, 50 run right after the other) inducing a headache, and I run my .243 Win. bolt gun readily with no discernable ill effects. Back to handguns, I have not found the recoil in any of these revolvers to be objectionable with a cylinder or two; but I have not had the chance to actually sit down and run 50/100/150 rounds through a given handgun (all my buddies), so I do not know how recoil will affect me in the "long run". Anyways, to make a long question short... how much recoil is too much recoil ? Would I be best advised to stick with something along the lines of a full sized .38 Spl and .22LR and a light recoiling rifle/shotgun ? Thank y'all in advance.
