Finding the BEST load.......
When you are trying to work up the best load for a particular gun, how many rounds of a certain powder weight do you make?
Example: I found that 5.3g of W231 under a 230g FMJ works great and is very accurate in my Ruger P97. I want to see if maybe 5.2g is better....or 5.4g How many rounds should I make of each of those to check for accuracy? 20? 50?
