I have no idea what a Marlin Cadet rifle may be (lever maybe?), and I have never loaded the 32/40; but years ago I took a perfectly fine Marlin 336A and replaced the barrel with an original NOS 24" Marlin Model 93 (?) barrel chambered for 32/40. Afterwards, the gun sat un-fired in my safe for nearly 20 years until I dragged her out about 2 months ago and completed my "renovations". I shot the gun at the "range" last week and was amazed at how well this little gun performed with a stiff factory trigger and cheap Bushnell scope. My improvised range was an abandonded rock quarry, my improvised shooting bench was leaning across a large chunk of granite; and the range finder said 137 yards across the pit to my 9" paper plate target with orange target dot. I didn't expect to shoot 1/2" groups, and didn't (don't think I'm capable); but the little gun grouped under 2" at that range, more than adequate for a proper kill shot on Whitetail deer. The loads used were factory new John Wayne commeratives with their snazzy nickel plated cases topped off with 165 grain flat nose copper jacketed bullets. This gun, recoil wise, was not the least bit uncomfortable to shoot. I was so impressed my "findings" that I intend to see what this little Marlin will do on Whitetail this season; good luck with your project and have fun.
