You have a bad case of "bullet setback" which can spike ignition pressures very dangerously (though .45 acp is a fairly low pressure round to begin with).
Golden Saber bullets do have a slightly larger diameter at the base than at the body of the bullet, but I don't think that would necessarily cause an increased incidence of bullet setback. I shoot a LOT of Golden Saber in .45 acp (mostly my reloads) and haven't had such a problem. To be really safe, don't fire those rounds. With a high pressure cartridge such as .40 cal., even a 1/16" setback can potentially cause pressure to double - a common cause of gun kBOOMs in poorly reloaded forties - especially when fired in guns with reduced case head support!
With properly crimped bullets, you should not be experiencing that degree of setback unless, perhaps, the rounds have been chambered many times without firing... but even then, I haven't seen such a case with well made ammo.
Call Remington and ask them to replace the ammo.
