That's well under 1%. Actually, inside 200 yards, I doubt that small weight difference has a large impact on group size. Certainly not enough to account for groups that large! It's much more likely that your barrel simply doesn't like those bullets. That's common enough with any bullet.

Yup, agreed. Sometimes you also get a bullet that your seating die just doesn't like and won't seat to a consistent depth, or with good concentricty. Have you checked that the bullets are seated to a consistent depth off of the lands, and the loaded rounds are coming out with the bullet concentric with the case?
If so - you could try different seating depths, or maybe a different powder charge. But unless you really badly need to use that bullet, it may not be worth the effort.
I've tried identical handloads in two separate guns with the same chambering. One loved the load, the other sprayed bullets all over the target....
