Was rocking a 14g hammer but trying the 13g now. 160/125 50 shots. 62-67fpe NSA 33.2gr are 65fpe 938fps HN 30gr pellets avg 979fps JSB 25 Kings 1025 on PW7 Standard Dev of 1. On 175/145 got 2 magazines at 72fpe Didn't need that power when 65 will do for small critters. Transfer port set to...

Got it April 2023. I contacted the dealer, SPAW.

Was about to shoot my Maverick over the chrony, having just topped it to 250 bar, the Omega bottle max. When I picked up the rifle I saw the pressure needle at 265... then 275, then 300, then ... Removed bottle, degassed plenum and held the rifle at different angles. The dial face just spins...

Magnet in the lever bar housing...

Finished with the rail getting that 4th screw in. First removed all the bits down to the action block itself to fit in my drill press vise. Then depth marked the bit so not to go too deep risking damage. It is off-center due to the magazine lock. I made the hole the size I needed for the...

Roger, I'll look at that for sure. Thanks. Put the Mav on the sidelines tonight and made a custom rail for another rifle from a bar blank.

Sharing the custom rail I made for my Bullboss from a blank. 2nd one I did, first was too low. Will tap in another screw later so the rail has two points of contact to the action block. A step-bit was used for the counter-sinks. M4 screws, 20mm long. Normally I use black but all I had was...

I havent touched the fine adjustment screw yet. Standard Deviation of 1 is pretty good. :) Will see what shot count and speeds I get swapping hammer weights out.

Still 14g hammer but lowered final reg to 120, first still 160. 5 power level is best, SD of 1. Didnt do a full shot count. Tomorrow will change hammer to 13 and 11g to see.

This listing has been renewed

252bar fill, first 5 shots power 3 then switched to 4. 30gr H&N's : 992 avg over 45 shots (52 total) 68 ft•lbs. 600mm barrel, Huma power spring and 14g weight. Will keep regs at 160/130 and try power at 5 then see how lighter weights do, but wasn't impressive first go at factory settings...

Anyone have the annoying issue where the bottle intake housing rotates since it isnt under pressure and cants the bottle to the side since it is off-set in which the rails then shave it like a razor??? There needs to be a bottom flat spacer to keep that from happening. Boo-Hiss FX.

Swapped the horrific FX factory gauge for a HumaAir and love it. The results tonight: first set regs at 150/120 and velocities all over the place. I changed it to 160/130 and seems to be on the money. Haven't tried a full shot count but very tight spread for 68 ft•lbs avg 999fps. A few hit...

We don't have the same setup. Mine is currently a heavier hammer at 14g and a much higher bar pressure. If it is needed, remains to be determined. I am leaning more to power than shot count, but I'll try my regs at 150/120 next. Thanks.

So when I set up for today's session I noticed the power wheel was on 6. Duhhhhh. So shot one round off at max 7 and it was 1020fps, 30.86gr H&N [what I'm using for all these tests]. Then I decided to just dial it down and see what each level yields. Level 6 is similar to 5 just the higher...
