338 Ultra Mag and 185gr TTSX

I can't see any useful reason to go that light with a 338 RUM. A 338 Federal, sure.

But a 225 gr or heavier will have higher BC and MUCH higher momentum than a 30 cal class bullet, and can take advantage of the terrific case capacity of 338 RUM

Inside 300 yards, pretty much all modern cartridges are flat-shooting. Past 300 yards, heavier 338 RUM will give much better terminal performance than a 185 because a 185 is going to give up velocity in a hurry relative to 225 or 250. Barnes TTSX 250 has a BC of over .60. Guarantee you it's faster at 300+ than a 185.

Yikes!
The 185 TTSX at a mere 2,900 fps in a sub 9 Lb 338 WM (sands brake) is all the recoil I want to put up with.

I hope you find the load that works for you - and report back.
 
I concur with sgt-zim, I don’t see a need to go that light. A 225 gr Barnes TTSX has a b.c. of .514 and can be started out north of 3000 fps and a 250 gr Barnes LRX has a b.c. of .602 and can start out at 2900+ fps.
I’ve settled on those two bullets and the 225 gr Swift in my .338 RUM. The Swift worked great in Namibia last year.
 
Thanks for all the replies. I have decided to go with the 225gr Swift A Frame and Reloader 22 in my 338 Rum.

Reloader 25 gives me the best accuracy with that bullet.
 
While it isn't a RUM my. 340 Weatherby loves the 225 TTSX Barnes bullet over 88 grains of RL 22.

HI all, here is a Short update on our America trip, I currently in Houston and have 2 more meetings here before movings North toward Oklahoma, Missouri and Iowa, and from there I will head to Colorado and Idaho,I have been met with great hospitality and friendship, and have met several new and old clients and we are going to book the rest of 2025 season quick and have several dates booked for 2026!
That's a wrap, on our first hunt of this years season.

Hunting conditions are a bit tougher in South Africa during the month of February, but can be just as rewarding if done right.
