My co-worker got into cowboy shoots and is trying to reduce his loads for low recoil. He's shooting 45 colt with 180 grain bullets with 4.7 grains of unique and it's pushing the primer back out of the primer pocket. Why would the primer be pushed out??

That would be an extremely low pressure load. I would be concerned about a squib. Could lead to a very dangerous situation. The pressure is so low that the case is not being pushed back against the frame of revolver after ignition. That is why the primers are protruding out of the case. I would try a different powder or at least more unique. Get some manuals and for tier 1 cowboy loads. Unique is a very popular powder for .45 Colt. Trailboss is the safest powder to load cowboy loads, but not the cheapest.
Unique is one of the best and useful powders for .45 colt loads up to tier 2 loads. But if he wants that light of a plinking load he may want to try something else. If I may what handgun is he shooting the loads from?
