Looking for your help on my Savage Model 111, 7mm Rem. Mag. I limit this rifle to 3 shot groups with long cooling times between volleys. Doesn&#39;t matter which reload recipe I use, one of the three shots is at least an inch or more from the other two (which are always < one half inch). Could be the first, second or third shot, doesn&#39;t matter, one of them will "walk". I called Hornady, they said adjust the recipes then the bullet seating depth. Did that, no help. I called Savage, they couldn&#39;t explain it but this model/caliber with the sporter barrel is only expected/guaranteed an inch and a half moa. What do you think, any insight?
