This isn't a clone, but it's an irish red ale (Killians is a lager IIRC), that I really like. It's the best beer I've made to date (I'm on something like my 6th or 7th brew now). Might want to give it a try. I just found it somewhere out there on the web.
Ingredients
7.5 lbs. Extra Light Malt Extract
1/8 oz. Roasted Barley
1.5 lbs 120 L Crystal Malt
1 oz. Northern Brewer Hops (30 Minutes)
1 oz. Tettnang Tettnanger Hops (5 Minutes)
1 oz. Cascade Hops (1 Minute and Steep)
1 tsp. Irish Moss
1 pkg. Irish Ale Yeast
Place 2 gallons cold H2O into a kettle and add grains. Bring to 150 degrees and hold for 30 minutes. Heat to 170 degrees and then turn off heat and let set for 30 min. Remove grains and bring to boil. Add extract, and 1st hops and boil for 60 minutes. Add remaining hops per the schedule. With 15 minutes left in the boil add 1 tsp. Irish Moss.
