I'm sitting here waiting for my White Ultra Mag to come, maybe this weekend. I have to use either peep sights or iron sights in Oregon. I am leaning toward peep sights since I used them a lot in the Marine Corps(about 45 years ago). What do you guys think the best peep sight to use and will work on the Ultra Mag? Also one of you posted an answer to my question regarding loads and said they might consider going to a 200 grain conical in the Ultra Mag. Does anyone make a 200 grain in 504 caliber. I like that idea because I always favor a lighter bullet in my deer rifles. Any thoughts would be appreciated.
