Three rifles were on my short list:-

FWB
Steyr
Anschutz.

Having shot Tench's, my mind was made up.

Love mine to pieces.
Trigger - Superb
Lock time - Superb
Balance - Superb
Deader than King Tut.

Couldn't get the original barrel to work for me (suitable for 10m - definitely..... 12ftlb work ????)
got a BSA Barrel on it now and its totally predictable for wind now with superb groupings at 40 yards (i'm talking pellet on pellet near as damn).
Jens Lothar Walther barrel seems equally at home in her Annie and the way she's knocking down the tin chickens, another superb modification.

Tench does a great job at converting them, which is quite involved, and like any good well built rifle, only needs minimal maintenance (if it ant broke-don't fix it).

Its a keeper as far as i'm concerned.

I'd put mine up against any rifle out there for the same money. Its just me that lets it down, but the more i use it, the better were getting to know each other.

So are these available in 12flb or do you have to have them converted. And do you need to put a different barrel as they are meant to be 10m gun.

No, they are not available 12ft lbs, you have to get them converted, and usually they do not need a barrel change.

I measured the twist rate of the 8002 S2 barrel at 18" so faster than a BSA but slower than a Lothar so no need to change it "because it is a 10m gun" or based on the twist rate. Several of the ones being used on the HFT circuit are winning stuff with the original barrel still in them.

Hi Tench.

How do you work out the twist rate? I've heard this couple of times but no sure on what it is... I'm guessing it's how the pellet rotates.

Best way is to get a cleaning rod, stick a patch on the end as if to clean the barrel and carefully push into the bore keeping it straight with no sideways pressure on the crown.

Work it up and down to get it nice and smooth, then push until almost fully into the barrel. Take some black insulation tape and wrap around the cleaning rod and make into a 'flag' that sticks out the side, this will show the rotation rate.

Make a note of where the 'flag' position starts then slowly & smoothly pull the cleaning rod out stopping when it makes ONE complete rotation. Obviously you must allow the rod to rotate, so hold in such a way that it can freely move.
Now carefully measure from the muzzle end to the bottom of the tape in inches, whatever this reads is your twist rate and is written as 1:16, 1:17 etc meaning 1 twist of the rifling in X inches.

Repeat this a couple of times just to make sure you have a correct value.

only in some cases you might not get a full rotation if the barrel is not long enough so measure the distance with .5 of a rotation ie 180 degrees then double the measurement to give you the correct figure. eh Tench

As Tugg points out, often the barrel is shorter than the distance a full turn would take so for example a 14" long barrel with a 16" twist would have to be measured over half a rotation and doubled.
