100m match March 13 in The Netherlands

[100m airgun]

Hi shooters,

On march 13 there'll be another 100m match in the Netherlands. Participants are doing the last preparations on themselves and their material. We are expecting a very exiting match since experienced 100m targetshooters with AA S4/5 series, modified HW100's (polygonic barrels etc.), BSA R10s, Daystate Airwolfs, Theobens and other rifles will compete.

Here you can see results of matches that we organised before.

Here you can see a movie of our 100m match of august 29, 2010.

In the evening (CET) of march 13 the winners of the match and their material will be announced .

Hi all,

These are the specs of the Lightstream HW100

1. the barrel
this is replaced for a Lothar Walter polygon barrel in .22 600 mm long
just make a copy of the HW barrel bud make the edge on the back where the pellet enters the barrel 0.5 mm larger so the pellet can enter the barrel easier

2. Fixing the barrel in the breech block
For this there are 2 extra grubscrew’s m4 drilled in to the breech , the location of these screw’s is on top trough the dove tale 10 and 20 mm in front of the center of the transfer port hole to clamp extra on the barrel

3. Loading probe
This is made 2,4 mm longer by drilling a 2 mm hole in front of the tip and soldering a brass extension tip on it what fits in the hole and is as thick as the loadingprobe it self
And has a 2mm side that centers it in the probe

4. The barrelband
In the barrelband there are 4 grub screw’s these clamp the barrelband on to the cylinder
Fixing the barrelband to the cylinder this is done because the stock of the HW100 has the intension to flex and by doing that the barrelband moves the barrel of its center
all so remove the o-ring that is in top of the barrelband so that the barrel becomes
free floating

5 The regulator
The regulator is turnt in to increase the pressure set it 0,25 mm deeper

6 The restrictor
on the valve stem there is a small bras restrictor this is replaced by a one that is tapered
on one side so the air can flow easier trough the valve

After these modifications set the power of the HW100 to 965 fps (jsb exact 15.9 grn) this will give 20 shot by a 200 bar filling 965 fps is what works best for a polygon barrel in .22
