1) I purchased some 30-06 M25 tracers made in St. Louis during the 60s-70s and described as " boxer primed and non-corrosive". To me, it describes the primer, not the tracer compound.
Can the tracer compound be corrosive or harmful in any way even if they ALWAYS ignite at some point beyond the muzzle? At what distance from the muzzle does this "model" tracer ignite?
2) The APs are black tipped and described as being made in St. Louis i.e. SL/53 or SL/54.
I have read that AP's are harden steel or tungsten cored, then covered with a) steel and copper or b) lead and copper. Since lead would appear to be a military no-no, it would seem that the steel core is clad in copper. That would seem to be OK if the copper jacket was thicker than the depth of the rifling, so no rifling could contact the steel core. Can shooting this specific ammo in military or sporter arms damage the rifling or other parts of the guns in any way? Thanks.
