NorgeX thanks for the information. Very good information. I have a Cimarron 1876 centennial in 50-95 Winchester and was looking to use Barnes 450g (I have 2 boxes) with IMR 4198. Do you use a filler with the 31g load ? And I found some load data that shows a starting charge of 35.8g of IMR 4198 in a Uberti 1876 50-95 and a max charge of 40.2g of IMR 4198 and was wondering if you or anybody used those loads in their 1876 rifles. They seem hot to me but they say they are safe in the rifles.
