Hw 100 Low On Power

[paulk73 151]

my .177 100kt is running slightly low on power. 10.3 to be exact with baracuda match pellets. i want to up it to around 11.5. is this easy to do with the you tube vid or is this a job for the pros? ?

Is it a new gun? Send it back under warranty. Mine was over at 12.5 but it came back at 11.4 perfect

Easy to do but like skot said if its new take it back ,try JSB heavies 10.3gr ,these pellets give more ft/lb than any other pellet in most guns

[paulk73 151]

no its not new. im currently using baracuda match pellets. they are quite heavy. it doesn't like the jsbs

[villaman 9,983]

If I was you I would try them ,mine is not that keen on jsb but the heavies are a different shape and gives me a lot more FT /LB than bis mags and any other pellet, if no good take the panel of the back , undo the grub screw ,cut a slot in the hammer screw or make a tool to fit in ,heat up hammer ,un do

had a look tonight. taken the back plate off, removed the grub screw but i need a grinder or something similar to cut the slot. will i be ok heating the tube up while its still attached or am i better removing the hammer from the rifle completely first??

I do them in place if you can get hold of a Dremel if not grind down a bolt to fit inside you know what bit

villaman. i tried the bolt trick it was solid. tgen i ueed the dremel to cut a slot for the screw driver. same mate. it would not budge an inch. think im gonna have to get hold of a new hammer assembly and change the complete part and adjust it til its right in the new one. ive looked on chambers spares and knibbs spares and both are out of stock. any ideas where else i coukd get 1 please??
