I have some old Hornady 300 grain flat nose handloads that hang up about every 3rd round. Since I intend to use it to hunt things that are entirely capable of killing me I need to be able to depend on it. It appears that the angle of the bullet coming out of the magazine is too steep.If it won’t feed 450-500 grain bullets, what will it feed? Is it the flat nose bullets that won’t feed? Or will it also not feed round nose?
