Re: Crazy grouping
Start over man, go threw the rifle/optic torque settings etc. Then, remember that VLD bullets are tuned with seating depths NOT charge weights.
Now that you have that info, find your rifles pressure limit. You will accomplish this by picking a seating depth and (mag length works) shooting a ladder test from min to max charge weight, until you see pressure signs. Its important to note that the deeper a bullet is seated the lower the pressure will be, that said, the longer a bullet is seated the higher the pressure. Once maximum safe pressure is established back the charge weight off 1 to 1 and 1/2 grains and shoot a 24 round seating depth test, the details of which can be found in the article I have linked in my signature line.
As always be safe and try your best to tune your load at a distance greater than 200m and of the utmost importance is to remember it is a hunting rifle, so don't go bang, bang, bang, bang, bang and wonder why its not shooting good groups, as you smoke your barrels throat. Do you shoot that fast at game? One shot every 10 minutes practice and plan for the cold bore engagement.
