What good are polymer coated 220 grain bullets?

Tested some of these in handloads in .30-06. Completely missed the target and cardboard backing at 50 yards after shooting 2 bullseyes with 110 grain loads. The accuracy is so bad they're not even good for practice. Why do they sell these things? Boxes of 250 available at Sportsman's Warehouse.
 
Going from 110 grain to 220 grain will change POI. They could be more accurate just not hitting the same spot as the lighter bullet.

A 220 grain bullet should work OK in a .30-06 but it is kind of heavy. 200 to 220 is pretty standard in 300 blackout and should get decent groups at 100 yards without issue.
 
That might be too fast for a polymer coated bullet, I think I read where 2200fps was max, maybe the poly was starting to melt or bullet was shooting erratically because of the coating.
 
Yes, you cannot normally use full-power jacketed bullet loads with most commercial cast bullets. Linotype or electrotype alloy with a copper gas check at a minimum, plus special lubes are frequently needed. Something designed for the Blackout won't normally be hard enough to hold up to full load pressure without special effort by both the caster and the handloader.
