You need to start at the minimum charge listed in the manual,and then work yourself up,not at 90% of the powder charge!
Almost any minimum load will cycle your AR just fine,but you want to find the load that will shoot the most accurate in your particular weapon.
Start at the bottom,and work yourself up at either 1/2 a grain or 1 grain increments.
When you find a charge that shoots best,then I will start at the previous load charge and work loads up at 1/10 grain increments until I find the very best load for that weapon.
Changing the bullet or powder,the process starts all over.
