I realize this may be a subjective question, but when is a primer pocket too loose such that it constitutes a hazard? I use a hand priming tool, so I can feel the resistance to each primer inserted. Some have more resistance than others. Does anyone have a guideline or rule of thumb they use to determine if a primer pocket is too loose to safely use the case?
 
If it surprises you how easily a primer seats, it's too loose. If it is a low pressure target load in .38 or .45 it will be much less critical than a high pressure round like .40 or .44 Mag etc.. If, after firing, you see signs of gas leakage around the primer, they are definitely too loose.
 
If it surprises you how easily a primer seats, it's too loose. I Agree.


What I do with those cases, since I was born to be frugal, is carefully push the primer back out (using a Wilson punch and safety shield) and trash the case and reuse the primer.
 
Actually the ease is relative.
For example I find it considerably more difficult to seat primers in Privi or Lapua Brass than say Remington or FC.
 
I have also learned that if you feel that the primer pocket is too loose you can apply a bit more pressure on the primer to cause it to spread a little in the primer pocket. Mark that case and relegate it to range only and discard it after firing it.

Or as Walkalong and Dave P have stated. Only you can be the judge of that...
