I have a Green Mountain Stainless 1-30 twist 45 on my Hawken.
I have had this rifle for years. I am using a paper patched RCBS 11mm rifle bullet.
Like I said I have used this rifle and load for years. I have taken Deer and antelope with it many times. I have the lead hardened to about 9 BHN. Here are a few pictures I have taken over the years.
While I would never take a first shot at an animal past 150 yards this load and gun with peep sights are accurate out to 300 yards.
