My 338 WM end up at 2869 for an average fps. It's a 24" barrel. I've shot/confirmed to 600 which is about my personal limit. I worked up the load a couple years ago, but haven't gotten to test it on any critters. I had used the 250 Berger and after a bad experience used the 200 SST and it killed like lightening. I'm hoping for the same from the 230 ELD-X. Huntingfool's experience gives me a lot of hope, but mine are starting out considerably slower.
