Hi DECKAPE:
If I were you, I wouldn't be changing anything either! Sounds like you're having great success both at the range and in the field.
I personally decided to not use PB.s after hearing some of the reports that you mentioned. Now that I bought a White UltraMag, I can't use 'em anyway, 'cause they slide right in and back out of the barrel.
I can't help but wonder if some problems are the result of guys driving them too hard. You're load of 90 gr Goex FFg is a nice load, and obviously has excellent penetration and expansion on deer.
... and that's my $.02
