so far i have only been able to smack a deer with a 240 xtp out of my 44 special going a blistering 1191 fps. it put the deer down right there. have not been able to collect one with my 45's and 250 xtp but that is on the agenda for this year. i dont see 1400 fps being unbearable in either gun, but have not been able to cram enough 110 in the 45 to get to that point yet. on a side bar, i use 210 xtps in a 41 magnum going somewhere near 1300 fps and it flattens deer like the hammer of thor. these days i mainly go for what load is accurate out of the gun i am using.
