Am loading 7RM ammo for my bud, headed for Africa in August. I want to use RL-26 with 160 NAB's. Will also try Fed 160 TBT's.
I've not seen temp instability with '26, but have not shot it in very hot climates.
Question, is that enough of a concern that I need to look at other powders, knowing it does get pretty hot in Africa?
Would appreciate opinions on that. I also have H-4831, 7828, H-1000, Retumbo, MagPro, etc. However, I like data I'm seeing, 160's in the 7RM with RL-26.

If it's not peaky in Louisiana May-June, I don't see it being peaky anywhere. Shoot it and see?

Bud likes NAB’s and I’ve seen what 160’s at around 3K fps can do. Look at JGRaiders African PG safari thread. He was shooting 160 NAB’s out of a 7RM. Did pretty well for him. DF

I remember seeing JGRaider's write ups as pretty favorable. While it's not Africa, my father and I have had good results on local game with the 160NAB at 2,900-3,000fps. He managed to stop one in a big TX deer, but that's the only one that didn't pass through, and I shot some large pigs with that bullet.

One was a 24" 7mmRM with RL22 for 3,000fps and the other was a 22" 7mmSAUM with RL17 for 2,900fps. The RL22 load is not what I'd run again, if starting over, due to the temp sensitivity, but I only hunt it in the fall/winter. I'll likely move to RL26 sometime soon, as I bought a keg of it last year. Just tough to ditch a load that shoots well when you have a few more pounds of powder to burn up. My particular rifle has a long, Weatherby-ish throat and takes powder charges above book max to make typical speeds.

I have a big jug of MRP, claimed by some to be a more refined version of RL-22. I doubt it's as temp stable as '23. Failed to mention I also have couple pounds of Canadian Enduron 7977. I've not tried it. It's in that general burn rate and may work well in the 7RM. Enduron powders are temp stable, about as good as the Australian Extreme series. DF

Since my RL22 loads were mentioned, thought I'd clarify. Those loads will run 3020" when loaded and shot in 20-70* temps that I hunt in around here and in the TX Panhandle. I've never had any issues with POI shifts, POA shifts, etc. I've never done any temp sensitivity tests since I've not had any of these mentioned shifts. One year I took 160's loaded with Retumbo @ 3100'....no problems at all. I know you know this, but August in Africa is mid Winter, and temps are very, very similar year round to West Texas.....dry and warmish. 160AB's and the 7RM is a great combo.
It is irrelevant what you think. What matters is the TRUTH.

I'm going to send my bud a link to your Africa thread. DF

As we mentioned in another thread,I'm also a fan of the 160 grain Accubond at a muzzle velocity of around 3000 fps. I have used it and a couple of other 160 grain bullets on everything from antelope to elk with very good results.
Hard to see how you could go wrong with it.
