I do not have the 22 X 243 Middlestead. Opting to modify the 224 TTH into my own design.
1. Barrel life: Like anything else barrel life isn't going to be very good with the larger bullets driven hard. A lot of bearing surface wearing on those bores.
2. Throat erosion: I did not go into this caliber with varmint hunting for rodents in mind. For hunting the species that you indicate you nor I will ever wear a barrel out, if its a quality stainless barrel.
3. I rechambered my first Savage 223 barrels to see what these cartridges would do. With the 1 in 9 twist and the 60 grain partition it flat out electrifies 200+ pound deer.
