Huntaria,
I agree if your having those kinds of eye problems then I would certainly go to a 9.3x74 or 62 for my big game hunting..Its just not worth it..

My .470 was regulated with 108 grs. of IMR-4831 and shot a 500 gr. Woodleigh soft of solid to POI at 2245 FPS (10 shot average with the high and low out) It bucked and twisted like and eel in your hand, was pretty horrendous to shoot..so I found that it also shot 85 grs. or RL-15 and a 5 gr. dose of Dacron for 2020 FPS to the same POI and at about an inch at 50 yards..It hammered buffalo as well as the 2245 FPS load as far as I could tell and I shot about a dozen buffalo with that load, so I never used another load in it..I notice this load shoots well in most 470s and to the same POI as well, and in all Searcys I have shot??????
