Quilly, I owned a 45-70 for several years to hunt hogs. I weigh about 155 lbs. and had to sell the gun because of recoil. I cut my eye two times at the shooting range and flinched every time I shot more than three shots. I am use to the recoil of guns and have owned many makes and sizes. The 450 has more kick than the 45-70. I believe with a muzzle break and good recoil pad the gun should be manageable for a person 180 - 200 lbs.
