Just got done with the .30 FX Boss update. My buddy Nick @socaloldman refinished the walnut stock for me and did an awesome job. I tuned the Boss just like my .30 FX Bobcat Mk2 (Reaper) so it shoots about the same, but more of a bench gun. Typical upgrades, Huma reg. set to 150b., larger Titanium valve seat, polished barrel, trigger adjust, set for about 870 FPS with .30 JSB 44.75 pellets, Huggett integrated moderator (whisper quiet), and as all Boss/Bobcat, very accurate.
So now though, I'm considering converting this to a .25 caliber gun to shoot Mk2 Heavy, since I already have one gun that shoots .30 pellets lights out. I "think" the STX 600mm barrel will fit with only minor reduction in the barrel diameter (outer barrel, not steel coupler or brass transfer port, since they already fit). Seems like the first 1/2 inch or so of the outer barrel need to be slightly less diameter, a few thousandth. Put in a Superior Heavy liner, tune for 930 FPS, change out the probe for a .25 Royale pellet probe, and I should have a very accurate .25 caliber 100Y bench pellet gun. Anyone done this to their Boss?
PS., thanks again to Nick for the impressive job he did on this gorgeous stock!!!
