No clue.....withoutsome very specialized equipment it would be a guess at best. This much I do know, there is no reason that pressure would be any higher or lower in a TC than in any other gun chambered as such.
Published max speed for a 32 gr. Vmax in Hornady ammo is 4225 fps. My personal experience with 3 different TCs in .204 loaded to my max with the same bullet gets me just over 4100.
