I've used .5lb, .75lb, and a full 1.0lb in 5 gallons. 1/2 lb was not enough for me, but was noticeable. .75 was better. glad I upped the hops a bit (extra .5oz of fuggles at 60 min) with 1lb in a 5gallon batch. I wouldn't go over 1lb per 5 gallons... and I love milk stouts! 1/2 to 3/4lb is the best range.
