I am amazed that so many of us have 45-70 rifles.
Count me in also....Marlin 1895GS 45-70 loaded w/ 300gr Hornady HPs over IMR4198 and topped w/ a red dot. Dad has used it to drop about half a dozen or so deer.
Also have a H&R 500 S&W rifle. Never fired it...I have the dies and brass, just never bought any bullets. My Midway Blem bullet order does have some coming though...only 50...should have gotten more I guess.
Those are the only big BORE guns I have...but have many more that are big POWDER HOGS, just not a big bore.
