Thread: Testing a conventional approach to load development

Had a crack at a 20 round group to get a better idea of my true zero and accuracy.
Blued Howa 1500, 308win, 20" sporter barrel, hs precision stock, Element Optics 2-16×50HDLR, Nikko Stirling zero-lok rings.
Shooting 165gn speer btsp's over ADI2208 in Sako brass.

5 shots then 5 minute break to let things cool down



Second lot of 5 shots (10 in total) then 10 minutes cool down.



Third lot of 5 shots (15 in total) then 10 minutes cool down.



Forth lot of 5 (20 in total)




I had one flier out to the right on it's own in the 3rd lot of 5 shots, I 100% know I pulled it I was getting uncomfortable and my back was spasming. It doesn't really matter but just worth mentioning. It was the first round of my 3rd 5 shot string, I got up and stretched after that and drilled the next 4 rounds back into the main grouping. I'm not trying to kid anyone or myself one outlier doesn't ruin that group.
20 rounds shot prone off my bipod 1.6" inside edge to inside edge is still plenty good and gives me a very good indication of my true zero.
Just want to say thanks @gimp your journey has been very compelling for me as a reloader.
Not bad for a $500 Howa in a flashy stock
