I have a small ring Mauser that was chambered in 7x57. It shot fine but after taking to be re- blued I could never get it to shot straight again. Tried a couple different scopes which I tried on other rifles with no problems. My question is can I change the barrel myself?
I was given 2 boxes of round nose bullets. 180gr and 160gr.
Now I reloaded the 180rn into my 300wsm for black bear. They shot extremely well 1.75 inch groups at 50yards. For bear it was fine with me and I did take a bear that never took another step. My question is I can't find reloading data...
