Shot a ram last year with my bow on a solo hunt. Took me about 3 days to get it done, can get really tricky in open terrain when sheep can see at basically 10x.
As much as I hear people say things about camo it can be very beneficial in these situations. I was literally arms reach from rams in the rocks as they passed by me and they had no idea. Good chance they would have had some idea I was there if I had solids on as they would have picked out the pattern of me.
