Thread: How do I Reduce Extreme spread in my .30-06

Hi guys

I am getting an extreme spread of 83fps in my .30-06 husqvarna 1640 measured with a Garmin. just looking for some tips and suggestions on how I may be able to get this lower.
I am currently using once fired Hornady brass that I brought on trademe. I full length sized it before using.
Ginex primers, 2209 weighed out with balance beam, 150gr sst set to 3.210 as per Hornady book- big jump to the lands but accuracy is acceptable. But often get a flyer, which I assume may be because of the ES?

Thanks in advance
