Potential HW97K damage?

[mikemorton]

It doesn't damage the spring permanently.

A spring kept under tension will lose power over time.

Three days IIRC, according to a recent article in Airgun World.

But as soon as it's re-cocked it's business as usual.

It wouldn't be a problem to leave it cocked for a long period of time,i've heard that it can actually do the spring some good to have a little bit of compression on it sometimes,any decent modern spring gun wouldn't find this a problem.

here comes another another one:

what fps should i expect with jsb exacts??

[Tenuc]

You should get high 700's. Impossible to say exactly as depends on the FPE of the gun. Most springers improve after the first couple of tin have been shot and the internals bed in.

[subfire91]

that gun advertises 951 fps but with lighweight pellets as weihrauch told me via email. Many reviewers say that after 1000 shots you should expect high 800's and very low 900's if you are lucky

[Flannelmeister]

My 77K which is the same gun inside is doing 780 - 785 with JSB exact 4.51s.

Going to cut a coil (maybe need 2) off the spring though to try to get it down to about 760fps. I want to get a lesser and smoother recoil and the difference in trajectory is negligible, about 1/8 inch difference at 45 yards.

[subfire91]

recoil is not a problem on that gun. It is minimal. i want to get the most i can from power though

In America maybe, over here, with normal pellets,that's FAC.
