These are the old bt's, they came in a red box that says Solid base ballistic tip, they come in 100 to a box. I have about ten left, when I get a chance I will run them through the chrony. I bought them to use in my 6.5 Jap, this is the first time I shot them in my 264, I just tried them see how my new scope works, did not want to use my supply of Partitions and ttsx, I hope they are as accurate as the Noslers.
