I think that I would have to agree. I would also weigh the ammo. I had a cranky check in person at the Tampa airport and they made me take my ammo out of my gun case and weigh it on the luggage scale. I was under the 11 pound limit with 40 rounds of 458 Lott and 40 rounds of 375 for 16 day safari.

Split the 458 to half solids and half softs (500 gr woodleighs) and for the 375: 20 235 gr barnes x, 10 300 gr barnes x, and 10 300 gr barnes solids.
