So, what did you group measure that you got at 300 yds.?So I watched the podcast by Hornady titled your groups are to small today. So I had about 80 rounds of new Gun Werks brass loaded that needed shooting so I shot a 80 shot string at 300 yards . My ES was 137.9 fps. and my SD was 36.7 average feet per second was 3309.7 .
With my Horizon 22creedmoor my question is what should I expect them to be and does it really matter as long as my group was good ? Which is another question what is considered a good group at 300 yards for a old one eyed man?
At 300 yds. I'd consider a "good group" to be ~1.5" or less.
An ES of 138 and an SD of 36.7 is pretty bad, in my book. I once had an 50 shot ES of 97 with an SD of 33 when testing a new primer. That was the worst I've ever gotten. When fire forming some new Alpha brass, 80 shots gave me an ES of 29 with an SD of 6.2 that produced .418 MOA group ( this being out of a .308 Ruger Precision Rifle, but with a Krieger barrel). Typically my high round counts yield SD's in the single digits. The factory ammo (mostly match grade) I've fired has yielded SD in the mid teens and ES's no worse than 50.
Hope this gives you some perspective. . .???
