XS-7 in 243: Pretty good for 300 yds?

What's the accuracy of this weapon?
Would 22-250 be better as a popper?

Looking for actual experience with the weapon and the caliber.

Thanks.

Not familiar with the weapon, but 22-250 would be a better choice at 300 yds. I have both calibers in different guns, both are great rifles, but I would take the 22-250 over the 243 for long range any day of the week.
