Help me under stand burn rate.....

[tacks]

In Reloading manuals you’ll see “% case fill”, that is what is being referenced.

Thanks, Makes sense.

What do most consider a min percent of case load?

Looking at Gordons comparing to the Barnes book, GRT is listing most a 100 fps less. GRT also warns of the max listed in the book as to hot.

You want to be in the 90’s.

Use the loading manuals for data. That’s what they are for.

This is also why I like Nosler's online load data. They show case fill density relative to FPS.

I do a lot of loading for 308 in a 16.5 barrel, tho I’m loading much heavier bullets. Hard to beat varget. I don’t know what the burn rate is. But clover leafs are hard to shy away from. I’ve tried pistol loads but quickly went back to rifle loads. Varget, imr4064, aa2250 has been the most accurate for me by far. I’ve found sub half moa with all three powders mentioned.

Why do you say that?

Why do you say that?

Because the OP really just needs to use a reloading manual….

I know that compressed loads can be fine (‘can’ is the key word), but obviously the poster is new at reloading so I answered the question with a generality instead of simply repeating the suggestion to use a reloading manual again… which is the best answer for his questions.

I was going to say that from the beginning. Varget and 308 are best friends.
