About 15 years ago, I owned an Enfield No.4 Mk1* that was sporterized by Century Arms. The barrel was shortened about 4 inches, recrowned, and had a nice front sight on it. It had beautiful wood for a $150 rifle. Unfortunately I can’t remember exactly what I reloaded for it, other then 120 grain soft point bullets and BLC-2 powder. As mentioned earlier, it’s highly recommended to neck size only the brass. Otherwise a light yellow ring forms about a half inch above the rim. It’s from thinning of the case wall. Shortly after that ring forms, the case will separate. I only reloaded 4 maybe 5 times then scrapped the brass. With a scope, I could easily get 2 inch groups at 100 yards. Plenty good for hunting deer sized game, and it did a very good job of knocking down a deer.
