Doing recon for a new hunting load. I can’t develop the load in the temps I’ll be hunting so I’m using the most temperature stable powder I can find. Triple nickel (N555 from Vihtavuori) is the most stable I know of across temps. It also is very popular with top level f-class shooters. VV claims it was developed for 6.5 creed so I’m hopeful I will not just maximize velocity and consistency but temp stability as well. What are your favorite powders for extreme temperature spreads?

Here are my thoughts:

What distance do you expect to shoot?

What game are you hunting?

What Caliber? ( I assume 6.5 creed)

Will you be hunting at a higher elevation?

Maximum velocity does not equal consistency.

When I would zero my 7mm in 50 degrees at 5200 in October I found very little change hitting elk-heart-MOA at 8,000 in 30 degrees. But mine was at 200 yards. I used commercial ammo. I will say my rifle liked the federal blue box and was noticeably less accurate with the federal red box. Admittedly, 7mm has a very flat trajectory. I’m not sure about 6.5 yet.

I haven’t #reloaded for my 7mm yet but plan to within the year.

Please share your experience as you learn.

Yes, 6.5 creed. Excellent points.

Elk inside of 400 yards at 3,750 feet and up as low as 10*F.

I’ll be developing around 200-500 ft and 50-70*F.

As a loose rule of thumb loads are most accurate a bit off the max load so a powder with a higher max MV should be accurate but faster than a powder with a lower max MV also backed off to its sweet spot. I know that is all extremely loose with lots of exceptions but this is what I’m referring to when I was talking about maximizing MV. I couple that with VV saying they developed N555 with 6.5 Creed in mind and I’m hopeful.

I’ll be using Hornady ELD-X bullets. I know the gun likes the factory loads with those bullets.

I’m hoping to get 1-1.5 MOA. The real variable is how well I can shoot from whatever weird shooting position I find available when I find the herd.
