I just picked up some 270 140's from Trop Gun Shop in Elizabethtown, PA. Sorry, no number handy. They are on the dealer list though. I'm fairly sure there were some 150's sitting there but I was scared they would not fly well in my factory twist tubes.
The old 270 works well on our PA deer! At increasing distances as my knowledge and skill increase, I hope.
Good luck!
