A sad tale but the OP knows what he is! I shoot clays every week and actually enjoy cleaning my guns. Very satisfactory to clean off ever bit of grease and re lube every outing. I have been a sucker for specialist oils and greases all my shooting life, and whilst I realise that a thin coat of good old3 in 1 is probably all you need I am still drawn to the expensive. Current favourite is SCHMEIRFIX grease. Super sticky and stays where it's put. You need such a small amount. Chokes are removed every two weeks and even then there seems no need!
