......................... yeah you're right.
I am glad you finally realized that.
Your precious Hornady HE load for your .308
WILL NOT shoot good in every gun you attempt to fire it from. Just becasue Hornady shoots good in your one and onlyrifle does not, by any means, mean that my gun, or anyone elses gun, will shoot it beter than the hundreds of other loads available for a particular chambering. Actually the odds are highly stacked against it shooting the best.
The "best load possible" is the load that shoots the best out of a particular firearm with a bullet of proper construction for the animal being targeted. Regardless of who's name is stamped on the box.
Some advie for you..........It is far better to keep your mouth shut and let every one think you are a fool than to speak and remove all doubt.
