I did…but I didnt know exactly what that meant. How do you account for the POI shift on the bottom row?

Did you adj aim point or scope for bottom row?

I see the allure....I still like to pick up my 1979 ish 22 cal Crosman Model 1, 5 pumps, ~30 yards open sights, can hit the Twinning Tea tin 5 out of 5 times with the open "iron" sights...and its brass lined barrel......last time I was at the eye doctor, I got "shooting glasses" so that I can...

Putting some simplified math/numbers to what Cole is saying: +/- 10 ft/s velocity spread...at 50 yards the difference between a 870 ft/s pellet and a 850 ft/s pellet all else being equal is the 850 ft/s pellet got there 0.004 s slower...and dropped 0.00318" due to the slower speed....

I have watched Gert's videos too, but missed that comment or video...will run some patches and ck. Thanks! 190 bar reg-plenum pressure (that is how my Revere came from AoA) uses less air/shot, should also give a "faster" shot cycle-from the time the hammer spring hits the valve till the pellet...

So....was I shooting the 177 Beasts too slow too?....190 reg, MP HS, PW Max, ~970 ft/s, other than a POI change, 5 shots, one ragged hole at 35 yards....I guess I was...as that is way better than what I was getting at ~860 ft/s I am going to shoot the Exact Heavy at >870 ft/s and see if they...

50 yrds, 190 reg, MP HS, PW12: 1st 6 shots and I am thinking ok, these are tight…the next 4 …fliers?, wind?, fliers plus wind? My wind flag indicated no wind when I started, after the 8th shot i looked at it again and now maybe a very light intermittent wind. I stopped at 10 because it would...

Based on the previous discussion...I grabbed a few minutes between meetings this morning and replaced the LP HS with the MP HS, Reg ~190 bar, Started at Max PW to get the valve-velocity to stabilize quicker (still took 6 shots, 1st 6 were all 1004 to 993 ft/s even as I backed down the PW), ended...

When you say 4 ft/s spread..over how many shots? Does your velocity increase slowly as your bottle pressure drops and your regulator pressure drops?

I still have my Model 1, that I purchased in ~1979....replaced the pump seals several times, for a brass lined barrel pumper its open sights hit a soda can at 30 yards accurate

Next time I switch out to the .22 barrel in my Ghost, I made a note to test at those velocities...I know I def didnt' go that fast last time I was cking for optimal velocity...and will try the 177 at those higher velocities too ...

I cleaned both my 177 & 22 barrels and they both took some effort till the patches came out clean. And i started with a brass brush and Hoppes, then on to cotton mops with JB cleaner then Flitz polish before patches

lead pellets oxidize slowly …u can find references on how to sort of rehabilitate them…but they wont be like new, so i don’t bother nor will i put the through my rifles

I have emailed Huma, Daystate and BRK regarding optimal regulator set pressure range and have not heard back from any of them....My Reg .22 Revere arrived from AoA at 190 bar, and put JSB Exact Jumbos on top of each other at 40 yards "out of the box". My BRK 177 HP arrived with (what I was to...

Did the "same" thing. Tried a very heavy Neilson 177 slug, and FX V2 chrono didn't register..which it does occasionally ..so figured it came out too slow to be picked up or it just didn't register. Turned the Ghost's PW up to MAX...and loaded another...and same thing...and yes I did, I went...

The "tin" post got me thinking...went down into the basement and found my box of "stuff" for the 177 R9... Anybody remember FSI? That is where I got my R9 30 years ago...and their maintenance kit...also in the box, Beeman pellets (totally forgot about those...the Match Wadcutters is still...

Based on latest Bro performance update (barrel tensioner) those color inserts aren't just to identify spring tension but also act as a dampener.

Good info Cole. My 177 R9 liked the H&N Baracuda Match the best...and so I have a bunch of those empty tins that I use for my different pellets. I find the JSB tin's lids to be too easy to remove or too hard, where the H&Ns lids are secure and screw on/off easily. I had some self adhesive...

I switch between 177 and 22 HP on my Ghost…requires slight scope adj …I find .177 H&N Barracuda Match to be good to 50 yrd (when the wind is minimal) to take out the euro sparrows harassing the bluebirds. If i take the time to size and weight sort…those groups are on average tighter. I find the...

PCP definitely way more expensive that shooting my ~30 yr old tuned Beeman R9...but the number of "fliers" unexplained missed shots is practically zero with my Revere or Ghost...The hold sensitivity of the R9 drove me to layout the money for the Revere...The Ghost has me considering selling my...
