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.

Mule deer and Colorado elk seasons almost done! Hunters driving farm roads, looking for racks, their PH driving them along, I ask that you not pull into my drive. The buck behind me, on the boundary line of the GMU somehow knows. The hunter laughs, I would invite you in to see my Searcy rifles but social distancing prevails, darkness arrives and the buck slides away into secret tree grove...

Many thanks for re formatting my article for the forum

I served my time in both the bush and during the bush war

I hope it did it justice

You - sir - are well placed to make a difference
