I shoot my marlin guide gun 45-70 with a factory 300 grain Winchester bullet, I use it for a brush gun. On the bench at 50 to 75 yards I get good bullet groups and that's good for factory loads with open sights. I started reloading when the price of ammo jumped up, but for now I'm just reloading for my Ruger No 1. I was lucky to find a guide gun ported so when I do start reloading a hotter shell for that rifle it shouldn't be too bad. I haven't got a deer with it yet, but I'm sure a factory 300 grain bullet from the guide gun will bring a whitetail with no problems.
