.270 WIN
Background- dusted off the 590a1 today and shot about 60 shells of centurion .650inch single ball ammo rated at 1400 fps. Surprisingly accurate ammo capable of pulverizing clay pigeons at 35 yards. Wish I bought more than one 250 round case of it last year.
Issue- the rear sight does not stay centered on the elevation drum and will walk to a side after approx 10 shells. The rear LPA sight on my SPX does not have this issue but the A1 sight is definitely of a lower quality and completely different design. I understand shooting heavy thumper ammo will shake things up but either I need to add some type of material like grip tape to the drum surface to provide grip for the sight or Look at an alternative rear sight. Does everyone else with a A1 have this issue with their rear sight ghost ring not staying put when shooting many slugs? I totally get that a shotgun is not a rifle but the A1 and slugs or big ball ammo is actually accurate for being a smooth bore barrel, might as well have sights that keep a setting.
Thanks in advance for any replies.
