Don't set your heart on a 60" kudu bull, you may be disappointed.
Depending on if you have hunted a Kudu before or not and which area you are hunting in you should not pass up on a good shaped old kudu bull as you may not get another. If you have hunted a kudu before and are looking to improve on it, then you could hold out. Many old bulls of 47-50" with the right shape are taken as trophies each year. 50-53" with the right shape are beautiful trophies, 54-56" are RW record class bulls and are unmistakably big. 56-59" are remarkable specimens which would be very hard to pass up as you may never see one again. 60" plus well this is the holy grail of kudu and truly a once in a lifetime trophy.
I would not set my heart on a 60" bull and hold out for one unless you can live with not shooting a kudu on your trip.
Irrespective of the horn size, young bulls should not be hunted.
Kudu are difficult to judge to the exact inch and no experienced PH will put his c@&k on a block and guarantee, that is a 56" or a 58" or a 60", he will most certainly make you understand that it is a big kudu.
The most important is to enjoy your hunt, work hard and if hunting the right areas you will be rewarded with a great trophy kudu bull irrespective of what the tape measure reads in the skinning shed.
