Question on Temp stability

[champ198]

Have a question for you all on Temp stability on Powder.
I am getting ready to work on a 6 Arc I have in a gas gun. From all the reading I do the Leverevoloution powder shows to have the best velocity as well as the best ES/SD numbers from everything I have read.
But I have also seen where a lot say it is not temp stabile as some other powders.
I plan to hunt with this rifle this year so the temp stability is pretty important to me as during our seasons it might be 70 degrees one day and two days later it might be 10 degrees.
Have any of you all seen temp issues from the LVR powder that you would consider an issue?

I have Varget at home as well but it seems to yield a lower velocity but I know it is much more temp stable.
There are other powders that are listed for the 6Arc but they are also harder for me to get ahold of.
The only other easily obtainable powder for me is CFE223. But I have never used it so don't know much about it.

Just looking to get some opinions from you all that have more experience than me.

LVR is temp spikey. Load in 70 for that temp shooting to be safe and take the hit on velocity in the cooler temps. You can load develop for each temp condition, but mark the box with the cold stuff with blue tape or something to keep separated.

How your needs compare to other folks on the internet is always hard to judge.

If Leverevolution was supposed to be all that great at ES/SD as well as velocity, don't you think it would show up on the list of popular powders among the competition crowds? It doesn't show up, because it isn't that great at ES/SD or temp stability.... It does give some of the higher velocities, but it isn't popular in the accuracy and temperature stability games for a reason.

Ball powders and double base powders are not known for their temp stability.... Extruded and especially single base extruded powders are. Think of ones like Varget and H4350 for example.

That said, it may not be important to a hunting context with a 6 ARC.

If you consider the energy level of a 6 ARC and the range it would typically be shot in a game hunting context, it isn't likely to be that the velocity stats will need to be state of the art unless you are talking about shooting very small animals like rats and prairie dogs out past 400 yards.

If you prioritize reliability and a decent group size, it won't matter if the ES/SD is not the best. At short to mid ranges (under 500 yards), the velocity stats are not as important as holding zero and holding a decent group dispersion.

If you need to shoot very small, and do it in wide weather changes, then consider an extruded single base powder. If you don't plan to shoot tiny stuff, then nothing wrong with a ball powder if it performs. Good Luck and in for the range reports.
