Hi there, I'm loading up the 300gn Lyman 2640191 bullet with I4198 starting from 31 growns up to 34 grams of I4198, when I get to 1700+fps, I'll be happy with that as that will give me 1924ft/Ids, I'll then tweak it for accuracy etc, just loaded 3 each of 31, 32, 33, 34gns of I4198, with Puff-Lon, slightly compressed. I'm looking at some rear sights now, really don't know what to go with, Lyman or Marbles, 1873 or the 76 model, or a ladder sight. Of all my rifles, this one has real class and a look of authority about it, a true classic in my opinion, and I'm looking forward to hunting with it as your forefathers did. Our fallow deer here are available to hunt all year round, around the size of your whitetail deer, we also have Red, Sika, Roe, Muntjac, and Chinese water deer as well to hunt, Muntjac are very challenging as they seldom stop walking while feeding, this will be something I've longed to do, to hunt with a lever action rifle, a challenge that I will enjoy immensely.
