.482 is a typo?
I was mistaken, 482 wouldn't fit anything beginning with "45" lol
i think you are talking about the xtp Hornady has listed as #45200 in the product line. It is .452 and is made for 45 colt loads. 45 acp jacketed bullets are 451.
I suppose you could try it in 45 acp but OAL might create a feeding issue 230g is the heaviest xtp that they list loads for in their sixth edition manual.
