No doubt. I used to live in Wilmore just south of Lexington and I will vouch for you.

Working up loads in the summer almost anywhere in the USA and then taking said loads with you to Africa should settle things. The whole "Tropics" thing is overblown in my opinion. I know it doesn't always work that way, but if a fellow can do his load work the year before and practice with the sighted load throughout the preceding year of his trip, all the better.

In southern Africa, hunting in the northern Hemisphere months of summer means hunting in the winter, and mornings especially can be brisk. Yup, read that again, it does make sense!

Certainly, if a guy works up loads in summer in the lower-48 USA he can iron out the details easily. Here on the ranch we have snow as late as May and yet just two months later I have blown up several thermometers that maxed out at 125 degrees Fahrenheit that were hanging in the sun on my UTV. Very frequently the varmint rifle on the shooting deck is much too hot to touch and must be covered during spotting lulls. Ammo ditto.

Work up loads in the heat of a USA summer and in similar temps in Africa all's well. It has to be.
