tuning on the run ?

[Firewalker]

IS it conveniently possible to tune on a hunt for different animals ? Say you are shooting .22 cal for Squirrel ,along comes the opportunity to shoot that chicken stealing fox .
Can this "on the run" tune be done and a change in pellet for new target larger animal ?

Yes, like others have said, you need to do 2 tunes. I would recommend favoring your heavy pellet/slug with a high reg setting and settle for a "good enough" tune then crank the dial down to 1 or 2 and try a 14gr pellet and see if it stabilizes on your lowest wheel setting?

How about just adjusting your aim point to the brain?

Thankyou , I do not really do this , just wondered if it was something one could do in a hunting environment .

to clarify , your shooting squirrels with a light pellet and tune , you see the fox , now you want the heavy pellet for the kill at a bit more range . hence the retune . this was just explained as memorizing two tunes you have perfected at home then use in the field .

With a Daystate Redwolf - YES!

The three Korean rifle brands I've had... Shin Sung, Sam Yang, and Eun Jin, all had power wheels that had a huge range and no major poi change from switching ammo and power. Only the Eun Jin Sumatra had a magazine that would cycle pellets or slugs of different sizes without readjustment, though. The Career 707 and Saver 7000 had inline mags that had to have the feed adjusted. In it's current setup, my C707 has 12 click points can run 22 Premiers from barely coming out of the barrel to over 1100 fps but is quite accurate at any reasonable settings. The S7000 is similar. VERY accurate rifles. My Sumatra is a little less accurate but has more versatility because of the mag and also has a huge power range.

My Delta Wolf has an enormous range available but it's a few more seconds to change power than these click wheels. Same for the Red Wolf. The Ghost can change power in a couple of seconds but you have to set up the reg in a way to accommodate the powers you intend.

I have my Redwolf tuned in low power for 10.3’s in medium power for 13.4’s and high power for 16.1’s

To add a different element to the idea of multi tunes, I really like pumpers and at one time, set my Sharp up to go from about 10 yds on 3 pumps to 50 yds on 9 pumps... all holding at my zero. I carried this idea over to my Career 707 and could click up in power for longer ranges or when the air started getting low to maintain a zero hold. It takes some time to figure it out but it works pretty well if you stay within it's capabilities.

The thing about the C707 that's cool is the poi stayed pretty true at different powers. Some rifles I've had would change harmonics to the point of moving the poi all over.

Definitely doable with a gun with repeatable hammer spring setting. My low power example is my dreamtac compact in 177.
HS 1: crosman 690fps for cheap target works
HS 7: Hades 690fps for squirrels
HS 13: 13g monster 690fps for skunks, coon headshots
Because all settings/tunes are within 20fps of 690 fps my zero doesn't change or don't need to change a thing beside remember with mag/ammo goes with HS settings.

This is my low power multi tunes but as long as you tune the ammo in the speed range then you can do the same.

I do this for my .22 barrel. 160/130, PW 7 with NSA 27.5gr and PW 1 for CPHP's. Both shoot about 900fps.

Sure depending on your rifle... I have my dreamline set up as a pellet pusher.. twist of a knob and it's rocking slugs. But to be honest when I'm hunting I use slugs.. Im not carrying two different ammo afeild.. when the adrenaline kicks in with the excitement of the hunt... Heart racing... Watching your target closely...are ya really gonna take your eyes off the target to set your rifle to more power and slap in the heavy ammo mag... Probably not.

Yep.

With the Ghost, and for about a month, I've been running the .20/13.73 @ 810fps (20fpe) for field target and low power pesting, while spinning the power wheel to 11 for the .20 Heavies (makes em go 910fps for just shy of 30fpe) when I want to reach further out. "Zero" is good on the windage but of course a bit further out for the higher fpe "tune."

And yes, the reg pressure is a bit of a compromise on the low power tune, to be able to also get the heavier pellets moving fast enough to take advantage of their surprisingly high BC of 0.048.

Every time I have the gun out I've got tins of both open and go back and forth, simply spinning the dial.

It has been working great for my uses.

This example of "tuning on the run" is best coupled with trajectory data for both readily available. I taped this dope chart to the bottle and should give an idea of how it works. (Left column is distance, middle is clicks/holdover for 20fpe, and right column is clicks/holdover for 30fpe).

.20? Do tell

.20? Do tell

The fly shooting in post #387 was the first post with the .20 barrel in the Ghost, but post #390 is the explanation of how it came to be. All the posts after #390 have been about and with the Ghost as a .20 caliber gun.

(Seems when we share a link like this it includes text from the first post on that page, this one happens to be about grips, but the link should take you to post #390).

Just to add to the wealth of info here is another grip option which is a bit more verticle https://fab-defenseus.com/gradus-rubberized-ergonomic-ak-pistol-grip/
