I have my .25 Marauder set up with an ES of 20fps. Seems solid out to 75-85 yds. What do you hundred yard shooters look for in your velocity spreads?
Thanks,

What's an acceptable ES for long range shooting?
- Thread starter JohnL57
- Start date
20fps or less is ideal. If you've got your gun tuned properly (meaning: in balance, harmonious, not wasting air, shooting mostly with the reg pressure opposed to the force of the hammer)... then typically the best way to reduce ES is by weighing your pellets.
If you wanna squeeze every bit of accuracy out of your gun then your looking at: washing, sizing, weighing, and inspecting/sorting your pellets. A tedious, boring, and anything but fun task. While weight generally affects your vertical POI the most. Sizing & sorting will also help tighten up your horizontal POI (and fliers).
FWIW - my Redwolf HP shoots +/- 20 fps ES with straight from the tin pellets. After washing, weighing, sorting (sizing isn't necessary with the .22 Redesigns) I can get my ES down to single digits.

No expert here but I think less than 25 is what I've heard is desirable between the videos I've watched and content read on here.
I'm considering buying the components necessary to convert my .22 gen 2. What kind of accuracy are you experiencing at 75 with your .25?
Thanks,
Karlo

Hi, Karlo,
I just added a Hill spring and lightweight hammer and haven't taken it out to 75 yet with the mods. I've been getting around 1" at 60 yards in the wind, have to mow my range again before I can reach out to 75.

1" at 60 outdoors is great! I too am considering the light hammer and spring but trying to be careful not to spend to much on this rifle. I've really been having fun experimenting with different things and so far one of the most interesting mod for me has been graphite powder spray. We use it on aircraft brakes and its basically graphite powder that is floated in a solvent.
It goes on like spray paint then dries rapidly.
I sprayed it on the hammer and it dropped my ES to about 8! Then I decided to enlarge TP and now it's back up to 20 or so

Interesting.. so what effect is the spray having in the hammer exactly?

As a competitive Field Target shooter ... at State and Gran Prix events use sorted pellets and my rifle will stay inside an ES of 10
That comes in really handy at the further ranges, because even 1/8" can be the difference between an X and a 0

so its really just a way of generously and evenly coating the hammer in graphite as compared to applying dry graphite powder say with a brush. I would have to guess that the graphite powder (whether applied dry or wet) prevents the hammer from getting side loaded in the tube allowing for more consistent hits on the valve stem when firing.

Here is a real-life, detailed example that 25-30 FPS extreme spreads are plenty good enough for 100 yard airgunning; as recorded tonight.

Ah! I misread your post, for some reason I read it as just putting it on the hammer "spring". Makes perfect sense now
My vote is also an ES of 10 or better. My goal is always zero, but I start seeing grouping problems when a shot deviates 4-5fps (not talking SD avg).
