OK I'm moving to Hornady AP LNL press. I have been reading about a lot of problems with Varget metering well with this set up. I will mainly be loading 55 grain soft point - 62 grain ss 109. I have used BLC-2 with good results but hear there can be quite a bit of pressure change with temperature change. I don't like having a lot of different powders around. Doesn't mean I wouldn't use more than one but I would like to find one that works well and stock up on it. Thanks

Win 748. This powder meters like a champ.

Hodgdon CFE 223 and H335 are also ball powders that meter well.

All powders can have pressure changes with temperature swings and most of your Ball powder that meter best are generally known to most sensitive. That being said its not a big deal just work up your load when it's Hot and forget about it.
I have found that the new Alliant powders like Varmint and the Ramshot such as XTerminator seem less temp sensitive than say H335 or BLC-2 and all flow well thru my LNL progressive.

Can never go wrong with good ole W748.

27.4 grains of CFE 223 for 55 grain works great for me and meters extremely good.

I have loaded BL-C2 and W748 in .223 for years. I have not loaded any "MAX" loads, but most are close to the top end and I have not seen any pressure signs or POI changes with any of my loads. I shoot at an outdoor range when working up loads and shoot year round. The temps have ranged from low 50's to 105 degrees without noticeable changes in load performance.

Go with the powder that shoots the best in your rifle and if you are worried about temp problems, just do your load work in hot weather as DStroud said.

Hodgdon Benchmark might be your best bet for temperature tolerance, and it meters nicely even though it is not spherical. I've heard great things about the performance of AR Comp, which is supposedly temp tolerant as well, and I've been told it meters very nicely too but I've never tried it.

I've been using AR-Comp in my .223's & I've been getting great accuracy & it meters from a powder measure like a dream. The Mfg claims it to be very temperature tolerant, but that's not something us mere mortals can easily prove!...LOL

AA2230, 2460, TAC along with those mentioned above.

IMR 8208 GOOD METERING AND STABLE ACROSS A WIDE RANGE OF TEMPS

^^ This. All the powders mentioned above are temp sensitive, except 8208. But, I shoot several temp sensitive powders in my 223 and 308 ammo, it does fine. It's really not that big of a deal for shots under 300-400 yards. It will not vary that much. If you zero'd your rifle with a temp powder when it was 20 degrees out, and want to keep the same zero and trajectory, sure you may be off some when it's 100 degrees out. But rezero and keep shooting. I have run AA 2230, AA 2520, TAC, Exterminator, 748, R15, R22, all with good results.

H335, h322, blc2, imr4895, varget.. the last two don't do GREAT, but they're alright.

Thanks everyone. Last year when working up a hunting load I used BLC-2 and a 60 grain Nosler partion bullet and key-holed 2 out of three shots at 100 hundred with my final load tested so I may just stick with the BLC-2. Now I just need to find some more it.

H335 is has been great for me.

Yep. This.
