I got a Prochrono chronograph for Christmas and didn't know what I was missing. During load development the more data you have the better.
Using Remington brass, WSR Primers, 22.2 grains of H-322 powder, and Speer 52 gr BTHP Match bullets I achieved a recipe that hits consistant 1" groups with my Savage 840, which I feel is great for this rifle.
After initial testing of 5 shot groups using different charges, I loaded 10 more with this combination and achieved the same results. Average velocity from this is 3070 (on par with reload manual) and knowing this I can calculate the PBR easily using Point Blank.
I found it interesting how increasing charge increments slowly (in this case .4) showed a quick velocity climb to near 3000 then slower climbs in velocity .3 and .7 away from max, then a larger spike at book max. No visible signs to case or primer that I was near max, but the chrono showed the largest extreme spread with book max charge leading me to believe pressure is doing wierd things and to stay lower.
DO NOT USE ANY OF THE CHARGES I HAVE LISTED. ALWAYS FOLLOW DATA FROM TRUSTED RELOADING MANUALS. THIS IS FOR MY RIFLE ONLY AND WILL NOT BE THE SAME IN YOURS.
