So are you saying if it's printed somewhere it must be true?
I just grabbed the 49th edition of the Lyman reloading handbook, it's what was handiest. Page 172, 257 Weatherby
87g Jacketed SP H-4831 max 73.0g 3731 fps
8g more of the same powder, pushing the same bullet and your getting 189fps more out of the same length tube? Lots of variables and you read about zero free-bore and such, but again it must be true because everything wrote down has to be true.
I'll be the first to admit I'm far from an expert on anything when it comes to guns or reloading, but sarcastic posts are getting to be an all to frequent thing around here. And I didn't think Marks response was bad at all, the follow up to it sounds like it should go into the Gun Shop BS thread located somewhere else.
Guess what I will be the first to tell you that you do not know what you are talking about either the book you are looking at is one that has all the loads in it reduced because all the lawyers have caused the powder compinies to do so for liabilities. all the older books had much hotter loads. so you just gave a good clue you are not experinced with guns for very long. Now for your information I have been a gunsmith and a very experirenced machinist for more years the you have been around anywhere. One last thing I did not have one flatened primer and all were chronagraphed by me. with my 3920 fps 87 grain bullets.
