.338 federal -- ballistics

[krug4751]

Hello folks. I'm new to this forum although I've read many of your messages and have gotten a lot out of them.
I'm planning a plains game hunt later this summer and I like Federal's published ballistics for this cartridge. I've seen some conflicting information on Federal's claimed ballistics and would like to ask if any of you have actually chronographed those Federal loads. If so could you please let me know if your numbers are close to Federal's numbers?

Thanks very much.
