Start sending them a penny taped to the begging letter. Include a love note to Wayne. The calls and letters will stop. I guarantee it.
I second this.. seriously worked for both my wife and I. Life member here, American Rifle use to be a decent gun mag, though all the gun write ups were clearly paid advertising, but now the magazine is mostly political or begging for money.
NRA has good base line firearm and firearm safety classes/courses, good competitions too but I wouldn't join again.
