I will play with these parameters and see how they work, as long as they don't mess up my big bore Africa shooting techniques!!!
I dont think it will. If you shoulder and shoot iron sighted rifles properly, they all pretty much shoulder the same way. Head down and forward, rifle pulled snugly into the shoulder pocket, and if you are shooting a traditional stock, your thumb is along the side of the stock, and isnt wrapped around the grip.
If youre not sure about that last part, you'll soon figure it out, especially with the larger calibers.
