Surprisingly, nearly all of my rifles behave this way when I get it right at the reloading bench. A TTSX and a good LR bullet (usually an AM) hitting either the exact same POI, or the TTSX hitting just a tiny bit higher.
For conversation- The low shot was the fouler following a tube full of WO being swabbed from the bore. The next 2 TTSX bullets went into the same hole 1.5" above the fouler. 7WSM Montana and 140gr TTSX. 100 yards.
That group was immediately followed up with three 162gr AM fired at the next target over. Note POI compared to the 140TTSX.
When I work it just right, I can swap ammo completely interchangeably. Which one I grab simply depends on the application.
