Thx gundog, I know SFA about Sambar unfortunately but that book has been quoted a few times so I will keep an eye open for it.

I have had to bring the trip forward to mid June (again). I've just come back in from the range where I have started prep and practise with the two rifles I'm taking and found you had resurected this post.

The Garman GPS has arrived and I now have to get topo maps as back up.

Rifle One : The 9.3x62 with 250 Nosler Accubonds is zeroed at 200yards and is 3" high at 100yards.

Rifle Two" My .264 Winchester Magnum shoots sub moa with the Woodleigh 140 PPSN and is essentially flat shooting to 200 yards. I am going out this afternoon to check drop at 300 yards and chrono the load. 66 grains of 2213sc from a 24" barrel.

Edit: .264WM 140 PPSN is 31" low at 300 yards. Right at the top of the bottom heav(ier) reticle post. Velocity 3,012 fps.

I was thinking of taking the 7x57 with 154 Hornady Interlock spitzers but there would be no margin for error so it stays home.
