So I had my Bushy Varminter (24 inch heavy fluted barrel) out to the range for the first time today. I had put together some ammo with 25 grains of Varget under 69 grain Nosler Competition BTHPs lit by Remington 7 1/2 primers in Remington cases. The brass was well prepped; trimmed to length, mouth inside and outside chamfered, pockets uniformed, and flash holes deburred. The charges were weighed, not just thrown. Bullets were seated with an RCBS Competition Seating Die. For now, I have a Burris Fullfield II 3-9 X 40 Ballistic Plex mounted.
My groups were only so-so at 100 yards, averaging around an inch. When I moved out to 200 yards, however, my groups were dramatically <span style="font-style: italic">smaller</span>. I mean like the bullets were falling pretty much on top of one another (I was shooting steel, so I couldn't get an actual group measurement).
WTF?
My ig'nint question is this: What could cause this? I didn't detect any major parallax in the scope. I shot under identical conditions at both distances...same bench, rest, ammo, conditions, etc.
I've shot guns that grouped the same at 200 as at 100. I attributed that to delayed bullet stability, but it doesn't seem like that could result in <span style="font-style: italic">smaller</span> groups at longer distances.
