The reason i asked is I have a mauser that i had a member here "Jkob" install a swing safety on, I really the gun but honestly when you push it forward to cock it , its a flat out B-TCH to close.
Where COC often catches people out is when they are at the range, taking their time, babying the rifle. When you run it like there are a platoon of enemy closing on your position, or when you have a chance at a quick follow up on a mob of pigs, you'll soon forget that it is COC. Doing a bit of dry practice, slamming that bolt back and forth like you want to wrench the bolt knob off, may also help here.
One other thought too: there seems a common practice in the US of "palming" the bolt. Here and in Europe people grasp the bolt knob between a curled forefinger and the thumb, which IMHO gives you rather more control.
Of course, another possibility is that someone installed a stiffer mainspring...
