In my experience with AR Comp, I don't think you are going to find any thing to worry about as far as temp sensitivity...

I haven't seen it, and I've probably gone thru 20 plus pounds of it so far...

I was picking it up since it came out in 8 lb containers... online orders

I was shooting H380 in my 22-250's but wasn't happy with how it behaved when it got hot on the prairie dog fields, it does some pretty wild stuff when it gets hot. I experimented with several powders and settled on AR-Comp. It gives me good velocities, accuracy, temp stability, and it was widely available at the time which was about five years ago. I laid in a bunch of it and still have 16 lbs in the locker if I remember right.

I like AR-Comp a lot, it's a very versatile powder with a lot of uses and it's consistent which is something I can't say for a lot of others.

Metering isn't something I pay much attention to because I've got two chargemasters side by side I use to weigh everything.

Been shooting the 69 TMK in the 223, TAC and CFE 223 run about the same accuracy, CFE runs faster.

Kinda off topic but I hit the local Sportsman's Warehouse this morning. They had put out a few pounds of Varget. They were only allowing 1 lb/customer. I snagged a lb of Varget and a lb of H4895. Seems like a little powder is dribbling through the supply chain.

TAC works great, but Benchmark , although not ball, is my favorite for .223 rem. Its accurate, good velocity, and meters well.

Set a meter a grain under, or even a specific size powder measure scoop, then use and auto trickler to top it off. No more issues with any powder

That would be WC844.
WC846 = Blc(2)
WC852 = H380. Be careful with 852, there were some fast lots that didn't meet milspec that were surplused, so start a bit lower than normal when you work up with it.

Shooters World Match Rifle's another good alternative, but right now the best powder is the one you can get.
Glad I stocked up when I did.

Benchmark is excellent, and it does meter nicely (maybe just not quite as smooth as H335, but not a problem). AR-Comp is an excellent powder, too. It's not quite as smooth metering as Benchmark but it's not nearly as balky as Re15 and the like.

Actually, the snobs here may scoff but the Lee perfect powder measure does pretty well with extruded powders. I keep a Lee and an old RCBS on my bench. I like extruded powders and the Lee does not cut the sticks like others do.

Are you saying "the Lee perfect powder measure does pretty well with extruded powders" because the measure doesn't bind up, or because you get consistent charge weights? Consistent according to WHAT scale, and consistent as in "within a half-grain," or what ?

I have 3 differennt powder measures gathering dust. The Lee is the only one I use. With Varget and 4895 it’s usually within a tenth of a grain. Close enough for general shooting. For special loads I set it just a hair low and dribble in what’s needed. My personal observation. Edk

I use IMR 8208 BR with the Sierra 69 gr SMK. Very accurate in my rifle.

This is some good info. Thanks for posting.
