I have owned my 91/28 TS carbine for over 40 years. They are a very good shooting carbine once you figure them out. First the lands in the barrel measure out to .268 instead of the normal .264. Some of the imported rifles were shortened by the importer cutting off the last part of the gain twist. and the Italianicon sight picture was really way off. They sighted the top of the front sight with the bottom of the V-notch. And the battle sight was set at 300 yds for the early models, later changed to 200. If you use the Horneday ammo or their .268 round nose bullet and have carbine or long rifle without the cut barrel and build up the front sight , 2 inch groups are no problem.
