Sometimes I just get the urge to post the obvious for various personal reasons.

Trying to figure out what load is accurate in your rifle is something you just have to find out for yourself. A rifle is a tuning fork, and each rifle sings a different tune. In order to match a round to your unique tuning fork, you must try loads on a trial and error basis.

In general, burn rates of powders can be generally matched to cartridges. Look through a few loading manuals and find a powder or powders that have universal acceptance between the manuals for a particular cartridge. After that, it is all up to tweaking, and trial & error to get that fork tuned. It might mean the difference of a grain of powder, or bullet design or weight, or primer type or brand, or even brass brand.

"What is an accurate load for a __________?" Only you will be able to determine that recipe. I've got loads that shoot 1/8" groups at the 100 yd mark, but that won't do you a bit of good when your rifle exhibits a different harmonic frequency due to rifle type, weight, barrel metallurgy, bedding style, trigger, etc.

Using forums and load manuals are excellent references to gather credible general information to aid in load development. In fact, I know of no better means. In suggesting forums, I mean to use them to verify the use of recommended data from manufacturer's manuals in practical application. (Sometimes there can be great difficulty using the terms "credibility" and "internet forums" in the same sentence) Credible specific information can only be generated at the range. Again, I know of no better means.

Though I make a living with a gun, its not for shootig 1/8" groups.

The OCW method is the accurate load for ________rifle! It is fast, and when shot "round robin" style can yield the load on the first day with a given powder and bullet. Some chamberings like the 308 will quite often shoot VERY similar loads and even seating depths, but most others are a bit more particular. I always answer with "my rifle likes__________.

But hey, a load range with a certain pill and twist can save someone a bunch of time by simply loading a bit under to a bit over the suggested loads, and that rifle should fall in there somewhere, unless it has serious flaws.

Time seems to be at a premium the older we get.
