I handloaded the old Speer 105 Round Nose in my dad's .243. For those East Texas deer they were still too stout, or that Lot was tough. He quit hunting after that year and sold the rifle. I remember Byron Dalrymple's writings on the 243 and 80gr for the Hill Country deer doing better than the 100 even. These were small deer. I think thats what alot of folks don't realize why Texans like to use the smaller calibers...those deer just don't take much killing. Now, those big West Texas Mulies and south Texas deer can be bruisers, but they still die form 243s! I too prefer the 80-95 grains in 6mm rounds.
