Slugging a barrel - 222 barrel and 223bullets- resizing?

[bandit86]

I just checked three 22lr rifles, all three came in at .222 and all the bullets we use came in at .223, one at .224. Is that normal? Would the bullet be better if it was matching the barrel?

I saw some 9mm HP that had the copper plating on the tip cut into a flower pattern to expand is flower pattern to do more damage, anybody saw that done on a 22lr?

How could you match a bullet to your barrel? All 22lr bullets are typically .223 with some maybe pushing .224 and nominal bore diameter is .222, I believe.

Neil waltz die can expand a bullet to 224 if need be, I think the paco tool goes from .221 to .225
