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.
How many are you looking for? I should be able to stop after work on my way home tommorow. Wow, a GOOD excuse to go! I think they had two boxes of just about everything on the shelf. We can work out shipping if they have them.
