Thanks Calhoun for your reply.
I had a feeling what you said was true, just looking for real world experience. I have developed successful loads using 165 gr. bullets and like these.
The reason I'm looking at these 2 bullets is because they are .100"+ shorter than the standard 165 spire pt version. I'm thinking I may be able to get a little more velocity using the shorter versions. I enjoy experimenting.
