I used a rifle for my private land only cow tag this year, it has been a long time. Usually I use my bow, but this year I wanted to use a lever gun.
I have an 1895 in 405, but not an original. I have some casting equipment and have shot some of my own bullets, but I have too many hobbies to get very deep into casting. But, my 405 shoots ok with as cast tumble lubed 300gr round nose bullets. I had 15 primed brass ready to go and a handful of bullets sitting there. So, I loaded 3 and check the zero and accuracy. They worked well enough so I loaded 12 more and headed out into the woods, within a half hour I had a cow standing broadside at 50 yards. One shot and she was done. The 300gr bullet had destroyed the onside shoulder and punched a gaping hole through the heart, stopping just under the hide on the far side.
It was the first kill for that rifle, and the first bullet I cast used to kill something.
Too bad the hunt was over so quick!
