Recently I posted a 183 yard minute of angle 1.45 inch 5 shot group and promised some 200 yard groups.
Having had the BSA shoot MOA at 50, 100, 125, 150 and 183 yards I am now chasing the 200 yard MOA standard of 2.094 inches ( 2 x 1.047" ). Didn't achieve it but did go close in the few groups shot.
Conditions were as good as it gets I guess. The five groups averaged 3.83 inches: 3.15; 3.43; 3.95; 4.00; 4.60 inches. One group ( 3.43" ) had 4 of the 5 shots in a tiny 1.25" or 31.75 mm.
Here are a couple of the five groups shot in very good conditions.
Here is another that had one shot ( # 4 )caught by a slight air change so I shot a sixth pellet to see what would happen. Five of the six measure 2.00 inches which is less than MOA ( 2.094" ); # 4 was off the target an inch or so.
BSA Hornet shooting average 904 fps with .22 JSB Exact 15.9 gr pellets. Fill pressure was 250 bar which this rifle accepts with the John Bowkett regulator. Leupold 4-12x 40mm AO Vari 11 scope set at 12x and zeroed at 155 yards. The previously described "air stripper" was installed. Bench rested on two sand bags. ME 28.8 fpe POI Energy 7.3 fpe according to chairgun.
Pellet drop from the 155 yard zero was 43 inches at 200 yards as per Chairgun.
POA was a paint spot on a curtain rod which was jammed against the back of the target stand to locate the POA 43 inches above the target sticker. There was the faintest of right to left air drift on the 125 yard flag for two of the above targets which then switched to a left to right drift for the other targets as the sun dropped below the horizon. Flags were placed at 25, 50, approx 80, then 125, and 200 yards.
This session was shot on a later day on the last farm trip after the 1.45" 183 yard target.
Judging by the limited number of groups shot so far at 200 yards it would seem to me that this rifle and pellets are capable of doing the trick in the best of conditions at that range; it is just a matter of time.
Kind regards, Harry.
