Interesting. Thank you! Did you realize an improvement in accuracy (precision)?….worth the spend?

Ah ok, not listed on web site, will call. Thanks tc

Hola Solo1, from where did you get the 28" barrel? tc

Hello Lee, not fully understanding what I just watched. It appears to me that when you put the new barrel end piece on and twist it to apply tension, it is basically trying to remove-pull the barrel and thus the breech end grub screw is what is trying to prevent that? Do we really want to put...

I use the magazine (Revere .22, Ghost, .177, .22) when tuning. I use the CARM single shot loader when using weight and head size sorted pellets in a vain attempt to hit exactly where I am aiming....

Sorry to hear that. I put one on my ghost’s regulator and find it to be excellent. Battery lasts a long time, allowed me to much more accurately dial in tune pressures, but more importantly it allowed me to see the dynamics of the shot cycle and further my understanding of the rifle. Logging...

Yes, they are supposed to be “dampeners” along with color coding so you know which spring is which

Read up on how to adjust the regulator, you can increase it under pressure, but if you want to decrease the regulator pressure you need to disconnect the bottle and dry fire until the plenum is basically empty...several posts on how to do that to prevent getting the cocking mechanism "stuck".

True...but I have a Sehkmet gauge reading PSI on my regulator/plenum...vs the dial gauge reading out in Bar...so when I was seeing the plenum "instantly" drop 50-60 psi ->4 bar, then take several seconds to get back to the starting pressure...I am not sure that would even "register" on the...

Ok, that confuses me....in that if the barrel-shroud is the same from shot to shot...how does it being too tight cause some fliers....as they were shot under the same conditions as the non-fliers, no? I thought fliers had 4 potential components not counting me shooting them.... 1. diff weight...

There isn’t one….

So...still thinking...while the spring will deliver the same energy, the heavier hammer will have less velocity, but higher momentum when it hits the valve...and will require more force to de-accelerate/stop it...so at this point I am thinking the heavier hammer interacts (requires more time)...

My 177 HP is very quiet, I hear two things when I pull the trigger, the snap of the hammer on the valve and the thwack of the pellet hitting the target a split second later. The DonnyFL Koi moderator makes report barely noticeable. .22 def louder, but 1/4 as loud as my .22 Revere tc

ignoring the weighted shim adding extra compression...a spring compressed "X" amount delivers "E(x)" amount of energy...so changing the weight of the hammer......unless it allows for more efficient transfer of energy from the expanding spring to the heavier hammer...should deliver the same...

yep, got it. Thinking about the physics of it...

so a weighted shim...that has a "shaft" that protrudes-fits into the inside coils of the spring?

I think the very slight differences in lengths (for my springs) is just BRK tolerances for cutting and grinding flat the end of the spring(s). But definitely different gauge wire...I haven't counted coils or micrometered all of the them... tc

My 177HP came with what was then the HP2 spring...way "over powered"...PW settings had minimal velocity changes, wasting air. I then acquired the LP, MP, HP, & HP1 springs...to shoot JSB Exact and Heavies, and the H&N BM I use the LP spring, to shoot the MRD and Beast is MP spring....to shoot...

Label on the bottom of the tin states... "4.52mm" ; right now its trending 60% 4.52 and 40% 4.51 ...probably why AoA doesn't attempt/want to inventory head size sorted pellets ...

13.54-58 gr, 15 pellets, (1) 4.49mm, (1) 4.50, (5) 4.51, (8) 4.52mm Going to keep sorting for a while yet but I have at least (8) to see how “tight” they will group tomorrow
