trappin em. how goods a hogs nose?

just wonderin how good you's think a hogs nose is. do you think they could wind about three kilograms of sorghum grain from around 400 metres given the wind was right? kuz our dam was the only water around and it would have easy to catch em but now its rained theres water closer to thick cover so their not comin into ours. but i know their pretty thick around 400 metres away. just have no reason to wonder that way anymore. i was thinkin start feedin em where they are then every day put the feed closer and closer so they eventually find the trap. i could move the trap to a good place but its a big job.
