Not questioning your readings at all. Just seems like 748 is not ideal. I think you would get quite a bit more with other powders, that's all. Not that you need to of course! 2750 with the 185 TTSX is not going to stop in an elk based on my experience. I've never seen results from a 338 Fed in anything other than a 22" barrel so I'm very interested in what you can get. Let us know what you work up! I'll bet you'd be well over 3100 FPS with the 160 TTSX with <max load of AA2230 (I get 3020 with one grain under Barnes max load).
