Yes, I was seated at the bench...butt on a rear wedge but I don’t think it hit my bicep...as I have reiterated, I know how to shoulder a rifle and the butt was square and sure into the hollow of my shoulder...as someone else pointed out, bruising can occur some distance from the trauma...and, as I have noted, my shoulder did not have a mark...
You should see what 525grainers do you you in a 45-70 loaded to Lev 3.


Think that is bad. Try a Winchester 1895 in 405 caliber from the bench.
I shoot a 4570 double rifle thats based on a shotgun frame of which i also own so its the closest comparison of 4570 vs 12ga. I load 405gr bullets to 1600fps which is the upper end loading for low pressure guns. A 1 1/8oz factory slug has more recoil than my loads. Stepoing up to factory levereverultion hornady 4570 loads recoil feels about the same as a hot loaded slug from a 12ga.
As you load higher pressures in the 4570 it will definitely feel sharper and harder recoil.
I have yet to shoot a 4570 load that woukd compare to a 2oz 12ga turkey load though. Those to me feel like my 458wm territory of recoil
Bicep brusing is from not holding the rifle correctly. You dont bruise where you dont get hit. The 4570 is an easy rifle to master even though at ruger #1 loads it does generate alot of recoil
Factory Remington 45-70 405 grain bullet at 1400 fps generates ~1800 foot pounds of recoil energy.
Factory 180 grain 308 Winchester bullet at 2600 fps generates ~2700 foot pounds of recoil energy.
When I use an online calculator I come up with a different answer.
308/180/2600 = 19.04 ft lbs
45-70/405/1600 = 28.44 ft lbs
There's a difference between muzzle energy and recoil energy...
any 45-70 boolit with 15gr of Trailboss is a pleasure to shoot all day long
You disagree with Newton? You just received a D- in 9th grade science class.
Newtons Third Law of Motion states that for every action, there is an equal and opposite reaction.
The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
