BTW, as you can see in the cross section pics the 240gr XTP MAG has a very thick jacket. While 2 pellets at 50 yards may work fine, you may not like its performance as the range increases. That bullet has the BC of a brick and loses velocity fast.
It was designed for 454 Casull type speeds and not 45colt. A 240gr in a 454 Casull has no problem hitting 1900fps. Your 2 pellet load is well under 1900fps according to the Triple7 load data.
This pic is of a 250gr XTP shot at over 2100fps into ballistics gel at 50 yards. Performance was nearly flawless. 209gr retained weight.
