Did she have a little bite to her Silvertip? Not bad shooting for the first time out. Your gun has a heavy barrel doesn't it? With the factory stock my Savage 110FLP would put the whoopin on ya,but after I put it in the Choate and filled it full of shot,I can shoot a couple hundred rounds out of it in a day. My Ruger #1 with the brake on it,still kicks like a 30/06,but it sure shoots good.
If you get a brake installed,make sure to get the gunsmith to make you a thread protector so you can hunt with or without the brake. Your point of impact might change a little so you might want to practice shooting with it both ways so you will know how much it actually changes POI.
