MOST ACCURATE LOAD
Some reloading manuals provide information as to what the researchers who assembled the data found to be the most accurate load for a specific bullet or bullet weight for that cartridge in the rifle they tested. Gets kind of specific, doesn't it? Think about it... It was the most accurate load in their rifle, with that bullet (or bullet weight, if several types of bullets are available in that weight). The number of times this has worked for me is exactly zero. The published "most accurate load" has always fallen short, sometimes way short, of what turned out to be highly accurate loads in my rifles. Further, the published most accurate load may deliver velocity performance significantly below what you bought the rifle for in the first place. For example, I know a shooter who followed published recommendations for an accurate load, and was disappointed that his 300 magnum was only making 30-06 velocity with the bullet he wanted to use. When he explained this to me, I quickly scrapped his load in favor of one that was shooting tighter groups at an additional 240 fps. That's more like it.
Don't get hung up on somebody else's recommendation for a load in your rifle. Read several manuals; spend a hundred bucks or so and carefully study what they have to say. Then, with some confidence, develop your own safe and accurate load.
Another thing to avoid... Don't get so hung up on accuracy that it becomes an obsession. Not with a big game hunting rifle. There are those who finally get their hunting rifle to shoot quarter-sized groups, and then think they must get them down to a nickel; or maybe a penny. They won't be able to duplicate that performance in the field; not even with shooting sticks or a bipod. Good enough is good enough. Only specialized situations require sub-moa accuracy, which usually call for a specialized rifle; not a typical hunting rifle. Be practical. Don't wear out the barrel and spend your hard-earned money trying to make your 7mm Remington Magnum shoot a nickel group because you saw one in a magazine. Besides, the gun writer who shot the group was probably flabbergasted when he pulled it off. What did the group before and after it look like? We'll never know.
