That small, maybe 0.1gn either side of listed weight?
If these were 300gn .338s I'd allow a full 1% of up to 0.3gn, but the .224s are so tiny 1% would be less than 0.1gn and beyond the capability of most scales to resolve.
Type also matters. The BC of a Partition is somewhere between "brick" and "brick wall", so I wouldn't sweat a variance there. If this was a Berger Match Hybrid it had better be less than 0.1gn because that's what I'm paying for with the premium for the fancy yellow box.
