That is an unanswerable question for what you are really after...
I have an XL7 in 25-06 that with certain handloads is sub-MOA. The bit of factory I've tried, and some handloads, No.
Brother in-law has the same rifle. His struggles with most handloads, but LOVES Remington Cor-Lokt ammo.
Does that make ALL X7's Sub-MOA guns?
If you want a garantee, several makers offer that; but you will have to spend more than $275.
