I changed my mine, due to the cost of brass, to go with the 50 Alaskan over the 50-140 and now I need some loads. form wild to mild!!!

when i get home i will post you the info i have on this. i use a cast bullet from an rcbs mould. it is the only bullet i cast. a friend who moved out of the area set me up for casting. it comes out around 535 grains, depending on alloy. my gun is a rem rolling block that i got as an action so my barrel is longer than yours. if you plan on hunting with this you will find that the deer do not like it very much but you can eat up to the hole. doesn't destroy much meat.

yes plese do I need all the help I can get
