Looks to be pushing bullets the quickest based on Hornady's load data page:

CFE223 is another option that's close to Leverevolution but they're both notoriously temp UNstable. This brings me to a newer powder offering that sits in the same burn rate - Staball Match.
Now, I've got no experience with this powder but have lots of positive experience with its sibling - 6.5 Staball. Has anyone tried this Match powder in their ARCs yet? How's it compare to Lever on the velocity front?
 
If you are wanting the most temp stable powders it's going to be varget, h4895, 8208xbr, benchmark, rl15. Fastest would be lever or cfe223.

I have burned about everything trying to find the magic. There is no powder that I have found that is temp stable and gives the highest speed. I havnt tried stabal match, I hate ball powders as it is.
 
Don't overlook A2520. I get great velocity and accuracy out of a 24" EABCO Accuracy barrel. 2520 is usually pretty easy to find also. My rifle slightly exceeds posted values with most Hodgdon data.

I'm unfamiliar with that powder. How does its temp stability compare with CFE223 and Leverevolution? Those velocities are pretty impressive 👌 I wish Hodgdon offered load data for the higher pressure boltgun group.
I have some experimenting to do on the ARC with the extended mag capacity the Jefferson bottom brings to the table (2.42") along with the higher pressures allowed by the Howa Mini.

I haven't noticed or specifically tested for it. I do shoot Prairie Dogs in South Dakota summer heat and haven't had any issues. Here's a blurb from the Accurate Powder page...
Most of our powders are not insensitive, and will show some effect at hot and cold temperatures.

However, we test at -40F and +125F and the deviation in most cases are ca 3% to 5% at these extreme levels. Therefore most shooters do not notice much difference under normal practical hunting conditions.

More elaboration on the subject:

Complete temperature stability can only be achieved with tubular extruded powders designs, either with double base (NG) and/or with other coating technologies.

Because the ballistic performance at extreme temperature is completely dependant on the specific combination, it is very difficult to quantify and qualify.

Our standard powders perform very well at extreme temperatures, and usually pass the strict military requirements by a large margin.

This is a subject that often fraught with misconceptions and inaccuracies.

The term is used loosely by manufacturers without qualifying the subject, and is obviously exploited for marketing purposes and perceptions.

The facts are:

Although powders can be improved, it's really only possible with advanced coating procedures and additives which increase the cost.
A particular powder can be improved re temperature stability for certain combinations, within a certain envelope which is specific to the following three main parameters/aspects
The caliber.
The weight of the projectile/bullet.
The performance level.

If any of these parameters/aspects go beyond or outside the intended ratio/s, the results will change and the performance will sometimes be different.

It is also very important that when a comparison is made, that all conditions re weapon i.e. components primer, case, bullet and the velocity are equal, and preferably done at the same time on the same day.

8208XBR if going for accuracy, lever revolution if going for speed. 25.5gr of 8208XBR put them into tight clusters for me with SDs of 5 or so.
 
Used STaBall match in a 6.5 CM with good results. Not enough to move away from Varget. But very accurate powder in Sauer Field Shot.
I was going to try it in 7-08 but got distracted.
