What part of se Vic Mickey? River trout tend to be small unless its that time of the year when they come out of the lakes to spawn..the gunpowder option sounds best.......makes me wonder if you are sambar hunting how you could give any of that time up for a fish,the deer reign supreme and the fish come a distant second on the list.
Though if you do fish a quiet river have a rifle handy as quite a few fishermen see deer crossing the rivers,but that is more so in summer when they are not hunted(as much)you never know
