I've been chasing long range airgun accuracy for 4 or 5 years now. And mostly trying to do it with relatively low power setups. The combined variables of "long range" and "low power" make it quite the challenge. While I do stretch out the distance shooting pests to much further, the metric for the long range/sub moa airgun has been simple, paper at 100 yards. Sometimes EBR targets, and sometimes just shooting at printed circles. About three years ago I moved into a house with 135 yards off the back porch. That easy access has been a blessing and a curse. I find myself out there at least 3 or 4 times every week, usually shooting to 100 yards. Sometimes it's even at night, after work and the kids are in bed. Lots of comparing and assessing whether or not a changed variable in the recipe (gun/projectile/speed/barrel/twist rate/choke/sizing/etc etc etc) makes much of a difference.
I finally stumbled upon one, the elusive airgun that AVERAGES sub moa, 100 yard groups. Now, many guys will share an exceptional cherrypicked 100 yard group that is MOA or better, but it's pretty rare to see somebody sharing results of a gun AVERAGING moa or better at 100 yards, at ANY power level. I've been shooting this gun/barrel/projectile combo for a couple months and can definitively say that it AVERAGES sub moa 100 yard groups. This is not the occasional cherry-picked moa group, but day in and day out, I can shoot 5, or 10, or 15 groups, measure them and average out the CTC and it'll be less than 1 inch.
Here is the most recent example. This was shot just a few evenings ago after I'd gotten home from a field target match. Hadn't scrubbed the barrel in a while so pulled the barrel and the shroud and gave the bore a thorough clean. Put it back together, walked some paper down to 100 yards, and shot this. The bottom right bull were my sighters, after that I moved up to the upper left and took 5 shots, then upper right, etc. That first group of shots that "counted" is stretched a bit right to left, telling me I should have taken a few more sighters to figure out the wind. The upper right had one shot drop low, about as bad of a flyer as this combo produces. The final 3x5 shot groups were pretty dang good though. So, the best and worst work out to 0.6moa and 1.4 moa. Average of the 5 shot groups is 0.95" or 0.9072moa. This is the first 29 consecutive shots after the barrel was cleaned (4 sighters and 25 counted shots). For those familiar with the EBR target format, out of 25 shots, 10 are 10s, 14 are 9s and the "flyer" is a 7. The EBR score would be a 233.
This is the second more recent example, shot maybe two weeks ago. I didn't use the EBR target, but just a 8 bull target. The larger circles on this printed target are 1 and 3/8" so it makes the groups look worse than the larger bull EBR targets above. There are 8x5 shot groups here, sighters were in the upper left, and "count" towards my average. This is also all consecutive shots, just like the target above. So this is 40 back to back shots. Again 100 yards. Best group was 7/8" worse was 1.25." The average of these 8x5 shot groups is 0.98" or 0.9358MOA.
These are not the only examples of the AVERAGE 100 yard sub moa results, just the most recent.
The primary parts of the recipe are: a BRK Ghost with a 12 land and groove, choked .20 Lothar Walther barrel shooting the NSA .20/18.9grain @ only 875-880, for about 32fpe.
