Opening up HW95k transfer port

[TORNADOS7]

Have a heavyish steel silencer on there atm, may try knocking up a weight for it but I do want to give this a go.
I've bought the reamers now, I have to

Fair enough buddy, out of interest what silencer are you running on yours , I'm also looking for a heavier silencer for my current .22/95k...

Ps, I'd thought about reaming the transfer port on my Xocet but decided against it in the end, the biggest difference was a reduction in piston weight, standard was 273grms and a proper tooth rattler, currently it's @ 255 and the difference in shot cycle is massive, so much softer/less aggressive than before, this gun has smashed just about every scope I've very put on it over the years, looking to reduce further still if I can, 240 would be nice...
