I am buying a new Remington 700 old style trigger for a stiller tac30 and i am wanting to know what kind of pull weight i can expect "realistically/safely" i can set this trigger to? I am hoping for 2lb. This will be a tactical type rifle and i think 2lb is plenty light. Will there be any springs in this trigger that i can replace to help me get a 2lb crisp trigger pull? thanks Lee
