not likely . @ 300 yards 2 shots would have to be touching and the rest would have to be inside the first 2 holes . 3 or 4 inch group at 500yds is great shooting .
Have you ever shot 300+ yards ? It's hard to keep your rifle still because of your heart beat .Your heart beat will make your reticle move 1/2 MOA or more every time it beats . ( ok now fill your puls thats how much your crosshairs are moving )Thats part of the reason you need to control your breathing . You need your heart beat nice and slow . Where you place the rifle on your shoulder can make your heart beat more noticeable .
If you have a problem with everybody .
It's not everybody that has the problem
