Bjorn Tore Posted March 23, 2011 Share Posted March 23, 2011 Hva skjer om en åpner trangboringa på et krommet hagleløp? Kommer krommen til å løsne fra løpet lengre inn enn trangboringen, eller er dette uproblematisk? Jeg har en star? IHZ-54 fra rundt 1966-68 med veldig trang boring, når jeg måler med skyvelær så er det ene løpet 17.3mm og det andre 17.7mm... Da skulle det største løpet bli "improved modified" og det andre er faktisk trangere enn "extra full" etter denne tabellen: http://www.colonialarms.com/pdf-files/page7.pdf Jeg vet det er mange som sier at gamle star hagler svelger "alt", men det er vel udiskutabelt at den er for trang å skyte stålhagl med.. Noen som er intressert i den forresten? Bjørn Tore Quote Link to comment Share on other sites More sharing options...
robert Posted March 23, 2011 Share Posted March 23, 2011 Måten å åpne trangboringa i Starhagler er vel å sage av et par cm av munningen. Vil tro kromen tåler det. Quote Link to comment Share on other sites More sharing options...
Sportskytter Posted March 23, 2011 Share Posted March 23, 2011 Gresvig åpner alle sine Star hagler som de inn porterer, jeg tror ikke de kapper dem. Du kan jo høre med børsemaker verkstedet demmes. Quote Link to comment Share on other sites More sharing options...

Bjorn Tore Posted March 23, 2011 Author Share Posted March 23, 2011 En Star fra 60tal....krommet løp Sikker på dette? Bare nesten.. Det er en her som mener de begynte å kromme løpene på den nest siste versjonen av 54'n :http://www.shotgunworld.com/bbs/viewtopic.php?f=83&t=36969&start=0 Om man kopierer det intressante (for meg i alle fall) så er det dette som gjelder: There were three variations of the model. The first one was produced around 1954 – 1958. It had locks with non-rebounding hammers, and the firing pins were accessible only from the inside of the gun. With the hammers uncocked, you can see the firing pins protruding from the breech face. The barrels were 750 mm long, the chamber is 20.6 mm and the bores 18.5 mm. The second version, made between 1958 and 1962, differs from the first in three respects. First, the barrels are chromed on the inside. Second, the firing pin housings are made of stainless steel and are screwed in from the breech face – so that one can remove or replace them without taking the whole action apart. Third, the hammers are rebounding. The third version (from 1962 to about 1968) has the same action and locks characteristics, but the barrels are drastically different. They are shorter (725 – 730 mm), tighter (18.2 mm nominal bore diameter), and the way they are joined together is drastically different; the previous versions’ barrels are simply soldered together, but on the third version they are joined by a sleeve at the breech (just like on all modern Izh doubles). The place where the breech meets the barrel tubes is marked by some engraving. These barrels were lighter and much improved the balance of the gun, but they didn’t shoot as well with big loads of big shot. Hunters were disappointed.

bobby Posted March 23, 2011 Share Posted March 23, 2011 Blev vel ikke så mye klokere her jeg heller, men jeg tror ikke ev kromm vil løsne eller blir noe problem for en kompetent bøssemaker. Quote Link to comment Share on other sites More sharing options...
