A new rifle is coming to the Netherlands, and Spain off corse.
The Toro from Lobo airguns
What do we have to do with it? Simple they want to shoot solids with it and they are missing some horse.
To be short, we have to find them.
The toro is a .30 kal pellet class rifle. The drill is common, messure to see what we have to work with, gutt it, and make chanches where we need to..
The goal? getting a V0 275m/s with 128 grain
We believe with this specifications you could get a nice shooting rifle witch will produce sub MOA groups @ 100m
Nice rifle. Nicely build and finish.
We have a nice stock with adjustable cheek piece and bedded with 2 bolts.
Everything is nice detailed, and the fill probe has a Foster design fitting. In few words a nice rifle.
Something to complain? Sure I an Dutch. We miss a picatinnyrail, and instead of a gauge I would prefer a fixed foster. And last but not least max 250 bar, 300 is better.
First we will slug the barrel with a pellet. We check for a choke and will measure the pellet to confirm the sizing.
A short chrony test to confirm the rifle will work as it should be, and check the energy.
Remove regulator so we can see what the rifle will do on familiar pressure off hour Beaumont's, 210-240 Bar. Think the main spring will fail so we will replace that first.
Gut the whole rifle and look what parts we can improve. When the rifle is on spec. we will diside we will keep the regulator (on higher pressure off course).
Life suck's .301 a dedicated pellet barrel, seems we have to get a LW .308 barrel.
Yesterday we got a .308 slug barrel from Kurvers Schietsport. It is not a LW barrel as we requaered first but it will do.
We did slug the barrel with .309 and we got some grooves and did not feel any nasty area in the rifling we will test .307 and .308 later on.
Enlarging the pass way to the chamber.
Barrel is machined almost to perfection, so lets move on to the next bottle neck.
To get maximum efficiency we need to smooth the internals.
And as we men know size matters so we did enlarge the valve housing.
And with bigger housing comes a bigger transfer port.
Because we want a bigger BOOM we did replace the some bolts by M5 steel bolts, and we did add a extra bolt to keep the upper to the lower.
OMG now thats a spring to close a valve,think they got it from a breakebarrel.
Infact we don't want a spring to close the valve, we want effincency and a max opening with as less impact from the hammer as possible and we want the air in the tube to close the valve.
No we dont, because some idiot witch name not to mention forgot a o ring at the TP area, and we needed to rebuild the receiver. However, we did a test shot barley 100 bar in the tube, original valve and a missing O ring. We had a 112 Joule with this setting, so we got same energy with a leaking rifle. i call it a positive test.
With a perfect valve hammer and spring we will get some real results. we also need another barrelband.
.
The new barrel wont fit the original barrel band so we need a new one.
As we speak we have 282 Joule 261 m/s. We will go to 275 m/s.
So we have another hammer, end cap, main spring and spring sleeve.
The end cap is sticking out i know we just dont want to cut the spring we have only 1. Second We like a long spring instead off a shorter one.
A long spring works smoother and gives more kenetic energy.
