I believe you are Spectre's buddy and he just has the same .300 Win Mag awaiting those darn high dollar optic's you both like, Ouch!!!
Being as the rifle is new and is probably not broken in don't be so humble just yet. Clean it and have another go, warm barrel, cold barrel, hot barrel...who knows when the 4 errant shots were fired. Slowly lighten the trigger until you are comfy and then about tighten it about 1/4 turn. Get a good bipod if you don't have one and go back to the range. Take Spectre and have him spot your every shot so you know which was which and you can think about what you did differnet or the same for each shot. Keep basic notes about the day, weather, shots, groups and compare them. Sort of like photography, you keep track of great pic's and what and how you took them so you could do it over and over. One day it will just all fall in place and be instinct. Trust me I am going to be working at it a while yet.
