Dusted off the Extra Heavy Barrel 1876 45-75 wcf today . Tried an open post , or the one with the hole on top of the post . Did not do so well with it , or was just not the right one . A friend gave me a small tin with a few inserts in it that fits the Winchester Globe sight . After a group was shot with that open post I decided to put the thin post with bead back on , gave the barrel a cleaning and went back at it . Target was a bit over 100 yds . and Yep back to the small groups this EHB is capable of . At 12.5 LB . that rifle is a treat to shoot . Not much but Its all I got ,,,,,,DT
