Not having varget sucks

But did you check to see if that sensitivity is really affecting the point of impact downrange?

It think that’s subjective. If we are talking about <200 yards, I wouldn’t likely see impact change but at a further distance I would see a difference, especially in the velocity. In my limited experience, 50-100 FPS can made a big difference.

I developed a killer load with CFE223 a couple of years back. It was in a relatively tight node, but it shot lights out. That load was developed at around 60-70 degrees (which is usually where I try for). It was towards the top of the pressure envelope. Later when I shot this load (coyote season) it was quite a bit colder. It was enough of a difference to pull me out of the node. I did not chronograph at that time. In early summer I shot with that same load and saw pretty big pressure signs. This time I did chronograph and it and it gained quite a bit of speed. I since switched to less sensitive powders and haven’t had the issue I have had with more sensitive powders.

When i was out of Varget I went to IMR 4166 shot the same load and group size was under 1/2 moa and the AVG FPS was only 4.5 FPS slower with SD under 10. It was no more sensitive temp the Varget and I live in NW AZ and shoot in temps well over 100.So basically work just the same. The IMR 4064 was slower and not as good as IMR 4166. I am shooting AI-AE 26in 1-10 m24 barrel.

That’s funny. I developed a killer CFE load with 175’s and while it picks up velocity when it heats up, it also lowers the zero which counters the velocity increase. The net effect is no poi change.

This is in FC brass.
 
I wish my luck was as good as yours with it. I use it in 556 and have pounds of it. I got great velocity with it, but it was too temp sensitive for my use in a precision rifle.
 
It’s not luck. I made sure the powder charge node and the seating depth node were wide enough to tolerate environmental changes. When developing a load you have to map out the node: powder charge vs COAL and pick somewhere in the middle. That way it’s stable.
 
Taggin in a bit late--I hear Frank et all talking about 2000 MR a bunch but do not see a lot of people using--it seems to be available.

I've never seen varget (only reloading a year) so IMR4064 is my BAE--since I have not much else to compare to it seems great. SDs very low (single digit) on 168 Hornady and ES is in the low teens.
 
either have to be flexable , buy another powder or take up fishing if you don't already , found 7 other powders that I can pick to use , some even better than h4350 while waiting to snag more h 4350 if it takes another year no lose to me as long as one or any of the other powders are available life is sweet . If one door closes another door opens or you could just smack your hear on the wall and create your own door nothing in the world is wrong with getting a group together to create your own powder company making varget for yourselves . I have no idea how one would do that but you surely could learn how maybe . I look at it like the problem with finding primers besides it being completely impractical you can reload used primers reload them and use them again not saying it will be the exactly the same as bought ones , but it can be done and some of the items you can use to do it are still pretty cheap online and . They do work well it will spark enough to set of the powder sending the bullet down range . Best of luck what ever you do .
