Sounds like a great trip, that's a lot of Bush Buck, can you show us some pics of them & what sort of length were you getting ?

I have a Weatherby Ultralight in 338/06 & 270Win (don't use the 270) great handling rifles !
What projectiles & weight were you using, as you had one of the best cartridges for the job you were doing for sure ?

160gr to 300gr (Ok 160's are no good in our Ultralights with all that freebore) I use 185gr TSX & get over 3000fps, even more with the 180gr BT now discontinued, so over 300Win Mag velocity, mild recoil & very flat shooting, all at 6lbs !

I just got some CEB 175gr but mainly to use as solids & expanding, not working so well so far as they need to be seated to far in the cases, but I have a plan to seat them below the bands by take the expander ball out !

Any way they have a 176gr Raptor, now that would be real good (if it shoots).

I really like Single Shots, but for this type of international hunting I would choose a Take Down bolt rilfe, I hate to say it maybe even a Blaser 93 ?
