I shoot a .50 Lyman Great Plains Rifle, flintlock. From what I've been told by the experienced flintlock shooters is that firing the ramrod downrange is not a matter of "if" but a matter of "when" and that the real question is "will you ever do it again?" Many men do, indeed, do it again.
Another good reason to use a range ramrod instead of a field ramrod to load your rifle at the range. A stainless steel ramrod with a bore guide and a billiard ball size knob on the end is going to be obvious if you don't remove it. Indeed, the knob on the end will block your sight so you can't aim.
Also, you barrel's muzzle will wear less without a wood ramrod wiping against it with who knows what abrasive stuff imbedded in it.
