Modified Gunpower Stealth 100 Yard Shooting UPDATED!!!
Hi guys, I managad to get out today and do some shooting out to longer ranges. Using 16 grain logun penetrators going about 850 fps.
I first zeroed the scope on at 50 yards producing 1/2″ groups with a slight breeze.
Then moved the target out to 100 yards to see what she could do.
This was my target. A roses chocolate tin lid taped to a large piece of sheet metal.
This is the target 100 Yards away. (The small square on the horizon of the field)
This was the view through the 3-9×40 scope I have at the moment. (I had to aim the start of the thicker crosshairs at the top of the sheet)
This was my first 3 shot group (One of them hitting just outside the target.) The second shot is just behiend the tape)
I then dialed in my windage and fired multiple shots, This was what the target ended up looking like, I noticed some grouped really well (3 touching holes near the centre, Some touching and close double holes.)
And where I was shooting from
I think when I get a 24″ barrel I will have more speed and the shots will be more consistant so groupings should improve

The group size was about 10″
That was shooting logun penetrators which have a lower BC and are lighter than the kodiaks.
Power was averaging at 800fps with kodiaks and about 850-860 with penetrators over a 20 shot string.
Took the barrel out today after failing at zeroing in the gun and realised that my rear bushing wasnt even tight, It was increadibly loose. This means that my barrel could move and the hammer strikes wouldnt be inconsistant.
Im desperatley trying to source a 24″ barrel on a budget but cant find what I want.
I think Im going to get a 22.5″ parker hale barrel and machine it myself or an 18″ barrel that is already cut.
I only have a small chinese mini lathe that is broken at the moment (Fried the motor) so I am tempted to get the ready cut 18″ barrel. But it doesnt come with bushings and the barrel is 12mm so bushings will have to be made.
Desicions…..desicions
I will try and do another 100 yard session with actually functional barrel bushings and kodiaks this weekend

Im using a gunpower stealth which is essentially a talon frame but a 12″ barrel.
Cant wait to get a 24″ barrel but the gunpower factory is shut until the 3rd of feb
Dave
what was the group size? I didn’t know a 12″ barrel could even reach out that far with any kind of accuracy…but what do I know 😯
Thread subscribed to. I can’t wait to see what your numbers are.
Hmm…
Removed flow restrictor in the valve
fully polished and ported the valve
extensive testing and chronying using more pellets than I can afford
and a lot of pump strokes 😀
Dave
Haha yeah i suppose you could look at it like that 😀

Got a list of the mods done to the gun?
nice post you did say those pictures were taken with our phone wow!! phone cost more than the Gun 😆 So what do you have Talon with 18 inch barrel?
Thanks, All pictures were taken with a 3G iphone camera.
I might be able to do some more shots with the bisley magnums (Kodiaks) to see how they group
Dave
Nice one, good pictures. 😀

Right guys, managed to go out again to do some long range shooting that was pleased with my results.
The gun:
Gunpower stealth modified
Ported and polished
Shooting kodiaks at an average of 800 fps with a high of 830 and a low of 785 over 20 shots.
Still using my 12″ barrel but this time the bushing grub screws were tight 😛
These are some 55 yard groups with a .223 cartridge for scale.
This group was 1.67″ c-t-c
This group was 2.825″ c-t-c
This group was 2.5″ c-t-c
And the last and best group was 1.25″ c-t-c
Then I stretched it out to 100 yards and got this group at 4.5″ The far bottom hole wasnt part of the group, that was from my brothers .223
Cant wait till I get this 18″ barrel
Oh and I now have found that I need a bigger scope. I have a 3-9×40 at the moment and even at 55 yards, the crosshairs cover the dot so I think I could shrink those 55 yard groups to atleast under an inch.
Might look at something like 6-24×44
