Harry Fuller testing .25 calibre EXACT KING
29.10.2009The good news is that your .25 calibre Exact Kings have produced the first ctc sub minute of arc 5 shot 100 yard ( 91.44 m ) groups that I am aware of being shot with this calibre air rifle.
These were shot at "Moffitt Range" in The Snowy Mountains in southern NSW Australia over this weekend. Even though it is now spring time the mountain peaks are still covered in snow.
The rifle is John Bowkett tuned BSA .22 Hornet but with a special BSA 58.5 cm .25 cal 6.35 mm barrel sent by John Bowkett for testing these pellets. These Exact Kings groups were shot at an average 271 mps / 890 fps ( 44.7 fpe ). The pellets were sized down to skirt size 6.35 mm for these tests. The rifle was shot over two sand bags as seen in the picture of the range further down.
As can be seen, this 5 shot group measures just 15.24 mm centre-to-centre ctc or 0.60 inches or 0.573 MOA. The first four shots went into ctc just 7.62 mm or 0.30 inches.
A picture of the range showing the rifle and the 100 yard target. Safe shooting is enabled to 500 metres into the distant hill.
One sequence of five of 5 shot groups at 50 yards averaged 11.81 mm or 0.465 inches The smallest 8.89 mm and largest 13.3 mm.
I measured ballistic coefficient from this rifle between 2 yards and 50 yards as being 0.039 at an altitude of 1234 metres which corrects to 0.034 at sea level. This I consider to be excellent for such a stubby pellet of this calibre.
This 25 shots string was chronographed at 6 feet from the muzzle when shooting the 5 of fifty yard groups. It showed an extreme velocity spread of just 6.2 fps or 1.89 mps. This is an amazing consistency.
This is a tribute to the amazing John Bowkett regulator installed in the rifle ( his own special, not the factory standard ) and to the minimal weight variance of the Exact Kings.
I have weighed 119 pellets from the remainder in one tin ( Ohaus balance scale ) and found the following:
25.5 gr ... four ... 0.03 %
25.4 gr ... 78 ... 65.6 %
25.3 gr ... 35 ... 29.4 %
25.2 gr ... one .. 0.008 %
24.3 gr ... one .. 0.008 %
That is excellent consistency.
