100 meter airgunning in the Netherlands

100 meter airgunning in the Netherlands

18.5.2010

A few years ago some airgunshooters in the Netherlands started matches with airguns at 100 meters. The reason for that was the increasing quality of airguns, pellets and airgunners. Of course, some airgunners were shooting at 100 meter earlier but there weren’t 100m-airgun matches. To start a try-out match was organized. Meanwhile many 100m matches have been organized and they are still becoming more popular.
The rules of our 100 meter matches are that contenders shoot in a lying or benchrested position. There are no limits in energy or calibre. The front of the gun is supported by a bipod, a beanbag or frontrest. The backside of the stock cannot be supported so there lies the technique of the gunner. Because the matches are almost always in a indoor situation a front and rear supported gun will make winning almost only result of the quality of the material.
Popular guns are Air Arms S400/ S410, Weihrauch HW100, Theoben Rapid, Daystate Airwolf, BSA Sportsman.
The smallest 5 shot 100m group that was produced during a match was 21,7mm. The pellet used was JSB Exact Jumbo in 5,52 mm. This is the most successful pellet that is used during our matches. Although there are no limitations in energy or calibre most gunners use energylevels between 30 and 50J in caliber .22. Some shooters that use Air Arms S400’s and Air Arms S410’s prefer the JSB Heavy in 5,52mm. Besides the accuracy of JSB pellets they are also preferred because of their consistency in weight. Although fanatic 100mairgunners weigh and select their pellets before every match.
In the years that followed 100mairgunners increased their technique and found out which guns, scopes and pellets were most suitable for 100m airgunmatches. We are very delighted that JSB made it possible to bring 100m-airgunning to a next level!

Harry Fuller testing .25 calibre EXACT KING

Harry Fuller testing .25 calibre EXACT KING

29.10.2009

The 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.
