Tejano, ye... new haven is on the barrel but its a darn small stamping ... its not that large noticeable stamping it uase to be ... I havnt spoken to winchester yet, but even a RH barrel would be acceptable ... the printing will be on the RH side however .... never thought about the extractor cut? Just got 4 boxes 130g Winchester deer ammo, around 3200fps.... was going cheap here in Adelaide.... will use it to get a feel for trhe recoil and blast and the brass obviously to reload the 160g...
