Hope some one can help me with this one. Have a BLR '81 that fires factory loads just fine, but won't fire handloads. Am using small base dies, micing each case, setting lengths to factory. The lever is hard to close, rifling marks show on the bullet, but the primer is barely dented after pulling the trigger, won't fire. I've been told it is a headspace problem, but am unsure how to proceed. I have tried re-adjusting the dies several times. Any suggestions appreciated--would it help to go to regular dies? Thanks-Karl
