Perhaps you need the chamber cut for the LOTT,lol. You could load it down closer to 45/70 loads, but it will still kick. Compared to the model 70 safaris, these barrels are light. Being a smaller bore, mine has more metal on it then yours though. Havent had, wait, havent shot mine with a sling on it yet, guess I better soon, and see if it tries to bite me. Notice the rough machine marks inside your action? Lil JB bore compound, and some boredom fixed that. Not real thrilled with the sights, thinking of a lower powered scope to put on top of it for this fall. Have an itch to take it elk hunting.
