    I'm sure Conor (him of the lists :D ) will be along shortly as he is using a BSA barrel on his Steyr.

    I've had one on my Steyr since end of 2007. It was the first one Leupy did for a Steyr! It's stood me well

    I would be very weiry of current BSA barrels as of last year, done three tried 4 in all and none seem to be any good.
    Know Con has both but uses his old one.

    Current BSA are a rifled liner pushed in to a tube and swaged giving a mild LG100 pattern in blank state.
    Certain fitments the outer sleeve will drop off at approx. 8mm diameter.

    Never known a bad CZ barrel.

    Jon has already suggested a CZ. I never hear anyone complaining about them. I would give one a try.

    Cheers.

    You don't want to know the price as of 2008 Fen wanted in excess of £400 each.
    Same barrels from a German dealer just over £215 each delivered.

    Not sure how much the P800 barrel was but came with the sleeve.

    Never known a mediocre CZ barrel, all good efficient and widely available.

    Came across a 1994 receipt from BSA the other day two barrel blanks £23. They were garbage gave em away some years back, double choked/swaged like most are.

    Could anyone steer me in the direction of a supplier of CZ barrel blanks?

    Where did you get that story from?

    I have a bit to do with BSA and as far as I know they are making their barrels in the same way on the same hammer forging machines they have always used on their own premises in Brum.

    Laity put his new BSA into the trophies at kelmarsh with a std production barrel, his gun was 1 week old showing they are as good as ever.

    BSA always produce in same old method on same olde machine. Heres some for gun tech's taken from BSA. CZ barrel is world class and not at all pellet fussy. Weihrauch barrels are also one of the best barrels hence accuracy of its spring guns and its HW100 series.

    BSA Barrel

    For many years BSA has been making gun barrels of the highest quality. Indeed, BSA is the only volume manufacturer of Air Rifles which uses Cold Hammer Forged barrels. These are usually reserved for use in high grade and military Fire Arms.

    Special steel is used for BSA barrels which work hardens when it is cold swaged to enhance the wearing qualities of the rifling. The barrels are produced from solid bar, this is deep hole drilled on specialist deep hole drilling machines, a method of manufacture that ensures that the bore is straight and has a superior surface finish ready for swaging. Many other air rifle manufacturers use tube to produce their barrels, however the process of "drawing" the tube can result in a "skin" forming on the surface of the bore which can result in a "flaking" condition during later machining operations.

    After deep hole drilling the barrels are rifled on a cold swaging machine where the barrel blank is passed between 6 rotating hammers, each weighing approximately 20lbs, over a specially machined tapered mandrel. To swage a single blank takes over 35,000 hammer blows. The action of this cold swaging increases the length of the barrel by 15%; work hardens the surface of the rifling, refines the grain structure of the steel, and produces a mirror like finish.

    The tapered mandrels are made from specially formulated tool steel, which is manufactured in small batches under laboratory-controlled conditions. It is then CNC machined to the most exacting tolerances to produce the finished mandrels, each of which costs well over £1,000 but is capable of producing several thousand barrels.

    The form of the rifling is reproduced as a mirror image on the mandrel. The swaging machine is able to accurately position the mandrel between the centre line of the hammers, and by setting its position up or down its tapered length, the size of the hammered bore of the rifling can be adjusted to very fine limits.

    A further big advantage of the cold swaging process is that it can be used to produce a "natural" choke at one end of the barrel. The normal method of choking is to finish the barrel and then squeeze the outside diameter to reduce the bore size, but in some circumstances this can distort the pattern of the rifling. However with the BSA method the rifling form is reproduced perfectly from the impression on the mandrel, with the bore gradually decreasing very slightly in diameter to give a perfect choke with considerable benefits in accuracy.

    Hw barrel .177 495mm long choked.

    Not hw specific so is 495mm long and it is 16mm so no sleeving for steyr chassis.

    Uk Neil is sending one back to me in the post tomorrow, it's been machined at the breech end to fit my steyr. Converted to 1/2 unf and a silencer coming also. I have measured one with vernier's and it was 15.98mm my steyr was 16.02.

    Hi Simon.

    You did say to me that they had been a bit hit and miss last year. You did advise me to stick with the barrel that is on my old 110 as opposed to trying a BSA. As for the production of the BSA barrel I would take Si!one word for it. Has anyone got a spare barley lying around???

    Cheers.
