.177 HW30S and HW99S for MPL shooting.

Yes the reach on the 99 is stupidly long.

Bob, I cut a coil off the spring, then compressed & re finished both ends to get it level, but it was still doing 11. So shot it for a while, then took another half a coil off, then another half, bringing it down to 9.
I then shot it for a few weeks, & found it had crept back up to 10, so another half a coil got it down to just under 9, with r10 pellets, & 7.8 with hobby. So another half a coil got it down to 7.6 with hobby's & thats enough.
Both ends are compressed & the spring ground flat to make it level, which accounts for the small drop in power. The shot cycle though now feels faster, just need a bit of shooting in to see how it goes now.

Interestingly, i have since also purchased a 22 version, which was low on power to start, & when i took out the spring, the 177 spring with 2 coils removed was the same length as the standard spring out of the 22 version.

As these are supplied in 6ftlb on the continent you could buy a domestic spec spring from Germany to save chopping your existing spring.

Hi Rich,

Now that may not be a bad idea as it would save a lot of time and work and the original spring could also be kept - or used to experiment with!

Do you happen to know a good supplier in Germany that has these 6 ft/lb springs and can supply them at a reasonable price?

I will probably chop my spring in any case as I like 'fiddling" about, but being able to buy a new 6 ft/lb spring would be very interesting to try and see how it worked straight "out of the box".

Bob.
