I find that if your loads are Black Powder or Smokeless at BP velocities, the recoil is very reasonable in all the "standard" weight or round barrel rifles. It is when you go for "Marlin Only" loads with 400+ grain bullets that things start to get uncomfortable!
I forget how many grains of IMR 3031 my heavy duty loads is (maybe 30 to 35), but it is extremely accurate! I got the load from Lyman #45, it is an "accuracy" load. The bullets are .458 quenched wheel weights with gas check, they are round as opposed to flat nosed. As a test for a back rifle, I used a 6" bullseye pistol target at 50 yards. With the Guide Gun loaded 4 + 1. Fire aimed shots as fast as you can at the target. My group was 1.34 inches in about 2.3 seconds. I have a Scout type base with a 42mm, no magnifying red dot. I never got around to replacing the iron sights. (Thought a Lyman 17 medium height with a Williams receiver mount peep, but I'm not impressed with the funky red ramp/fiber optic front sight!)
I was at dad's farm trying my speed drill. it was August and I was in a T-shirt. I fired the 5 shots and liked what I saw. Then dad says Lets see that again. So I did. When I was done the tears were flowing down my cheeks, The bruises surfaced 3 days latter!
