Mr. Montana Marine et al:
Read the original post, a 130 grain bullet in 25 caliber; I will now qualify it as a 130 grain "hunting" bullet and not a VLD.
Not trying to be a smart guy, just trying to gain an answer with my preferred level of credibility.... looks like you guys don't 'really" know.
Despite your illustrious artillery experience, I see no formula, nor a reference to a ballistics engineering degree (perhaps you have one) So, I guess I will call Sierra someday....
Unfortunately I don't share Shane's coolness, so you can shove a 130 bullet right up your ass [bleep].
