Old HW35 need to chrono it - then Upgrade

[Big Stu 12]

Hi, I am now quite close to securing a permission, as it happens with shooting rights.....

I have an old HW35 - .177 that I brought about 30 years ago, it has sat in the cupboard for about 20 of those years, now the question is what is the muzzle volocity.. so need to get it crono'd be for I take it out and do any work that needs doing to it.

Has anyone near Ipswich got a chrono that I can use?

and any suggestions on which spring ect to use... been a while since i ve done any Air gun work.

Should be able to chrono it at a gun shop. I traded in a theoben sirocco for an Air Arms S410 .177 when they chronoed the Theoben it was only pushing 4lbs! Wandered why the pellets were almost just falling out the barrel
Really pleased with these PCP air rifles would never go back to a springer or gas piston.
