6.5 creedmoor ar10 with 26 inch proof cam gas barrel,130grain berger vld loaded with 42.5 grains of h4350 Using hornady brass and ginex large rifle primers As title says I'm not sure what to do with this info as I have just recently got a chronograph and tested my loads that I have been religiously using. After shooting and recording my fps I got a sd of 21 with the average coming in around 2820. Is this good enough for a reliable deer and elk load? Is there something I can tweak to get my numbers more consistent with a smaller sd?will my cheap primers make a difference to tighten that up? What would you experienced rabbit hole chasers do with this load?
