littlebit. I should have bought the magazine, and saved the article. I didn't.
<br> Sierra found that with some bullets, the BC's change quite a bit with velocity. Their famous 168 gr. .308 MatchKing is a case in point. It has 4 BC's. And shape is a funny thing too. Their 175 gr. MatchKing is a short nosed, uninspiring bullet. Yet, it flies beautifully, and out performs all their others in the .308, especially past 600 yds.
<br> BTW, Jamison found that the Swift Scirocco 150 gr. 7 mm bullet really did have a BC of .500 or so. E

E,
<br>
<br>I have the articl;e and of course had read it.
<br>
<br>Computer generated numbers are just a starting point,but I've found them EXTREMELY accurate. Without doubt,you calculate your rifle's trajectory,determine a 100yd zero and be on a piece of notebook paper at 500yds,with the predicted MOA elevation adjustment(assuming a sound rifle and scope).
<br>
<br>You are 100% on the money,one simply must confirm EVERY piece of ballistics/trajectory data,through each specific rifle at each specific range.
<br>
<br>That's part of the fun.................

Littlebit,
<br>
<br>Actually I think it is the lack of balistic therapy. The range was closed the month of Dec, and while it has been open as of last Wed, I have yet to put in a shooting session. I really should go tomorrow, will feel much better wink

Lott,
<br>
<br>I have some old manuals from when I started reloading, and there is definitely a difference between loads from the early manuals and loads from later manuals. In reverse of normal trends, the later manuals show heavier charges.
<br>
<br>In light of my experiences with my barrel, I speculate that early chambers were cut tight, with normal throats. People got in trouble trying to overdo the cartridge and or didn't watch wall thicknesses, and TC decided to go for looser chambers with gobs of freebore.
<br>
<br>It's based on my having such a generous chamber, plus the additional 2 5/8" of barrel that I feel that I can get over 2500 fps without any issues. Only time will tell of course, but (damn that!!) Big Stick and his Ecks bullets may have me re-visiting the Herret.

I like 7 mags too, I have 5 of them. I like 140’s, but have wondered about loading the 120 Barnes.
