223 bullet grouping tests

Admittedly home loads but that’s a Sako 75 in 223 which uses the same barrels.

Only if there’s no wind, or the wind is completely constant, which it seldom is. The variation introduced by wind may not show up at 100, but could easily cause substantially more than 1moa worth of variation at 200.

Agreed, as distance increases so do variables and subsequently you will get greater dispersion. MOA is still an angular measurement and is irrespective of distance.

1-8” twist I presume. What bullet weight?

yes 1-8" twist and 55 grn bullets,

 

[long_range_rob]

yes 1-8" twist and 55 grn bullets,

There’s the issue. Go heavier. 60gn or more will pull those groups right in.
