Your experience may vary . . .
I am more in agreement with Diomedes than Jonny about Freak boring and my Phantom, I think the big mistake a lot of users make when first using an insert system is trying to underbore.
Underboring is a finicky thing, and generally with the Phantom and Freak-boring your not looking to underbore, just bore-match. If you stick a round into an insert and it's not easily blown out, it's too tight, if it rolls out it's too loose - inserts just need to "hug" the round and give you a nice "pop" when you blow through.
