I just got back from the rifle range with my Cimarron 1876 50-95 loaded up with 35.8g of IMR 4198 and Barnes 450g original fp bullets ( as I seen in the guns and ammo magazine article buy Ken Kempa) the load performed very well. I only used it out to 50 yards but I have a couple 5 shot groups that measure just over 1”. My eyes ain’t what they used to be but I’m not complaining about the groups. I took the rifle apart and see no issues with the rifle using this load as everything internally was still extremely tight. I’ll be loading up more of these very soon and I’ll give the 300g Barnes a try also and see what they do.
