300 Bar Charging - Weihrauch HW100

[Stan]

I got a new adaptor for my HW100 through my local gunshop who in turn got it direct from Hull Cartridge, cost around £14.00. Also I have found that it is better to have the gun charged to around 190 bar rather than the 200 bar max recomended by HW. If you charge to the max the first few shots are underpowered.

Probably get flamed for this but I put a couple of 8mm bright steel washers in front of the adapter and then fill to 200bar. Some people use a single bonded (dowty washer) but not sure of the size, probably a 1/4" BSP.
