Hi, I want to load the longest OAL cartridge length I can for maximum accuracy in my Blaser R8 in 308 Win. However when I do this it will not feed from the magazine as the nose of the round catches the underside of the barrel by 4-5mm. I wondered if I changed the magazine insert from .308 to 30-06 this would solve the problem as it should set the round back further in the magazine. I don’t want to buy a new insert to find it doesn’t work. Has anyone got a solution to this?
Yes you can change the magazine insert to a longer version. Blaser chambers it’s rifles right at SAMMI minimums, so unless you are using really long high VLD bullets for a given weight, I’m not sure the extra OAL will make that big of a difference. Any Blaser barrel with good ammo that does not shoot near or at .5 moa is a surprise to many of us.
