XTP's braggin' rights are that they supposedly expand at a very broad range of velocities.... from less than a 1,000 fps up to over 1800.....
That being said, I've never tried them at the lower speeds.
I do use alot of 200 Grn. .429" XTP's but at around 1400 fps. One of my favorite loads is 26.0 Grns of IMR-4227 and a Standard Federal Primer. Very consistant and accurate. Recoil is snappy but not too sharp out of one of my 4" 29's or 629's.
