Hello I love the OLD Buffalo bore stuff with the speer gold dots. The new stuff they use whatever bullets they deem necessary and they were deceptive in advertising and the owner became mad about it when called out so I stopped using them. I did buy about 20 boxes though and have a lot of it left and it is my carry ammo.
However the advertised speeds are spot on.
Remember heat and altitude make a difference.
Here is what I actually chronoed out of my 1st gen p3at that I have had for 10 years now.
