    I’ve found one thread that’s older but looking for current input

    How stable is this powder. If I load ammo up at 65F and then shoot in say 90F will it stay fairly close to same speed

    thanks

    In my experience, yes.

    Have no data myself to show you, but have seen some very impressive temperature stability data from it.
    It and RL16 both are made using the "TZ technology", which: "manipulates the response of the material and resists the natural tendency to generate more pressure at higher temperatures and less pressure at lower temperatures".
    RL16 is the most temperature stable powder I've ever used/tested, which encourages me to think RL23 may trend similar.

    I’ve shot both Donovan; same stability with both. 16 in a 6.5 Creedmoor and 23 in a 6.5 x55 BJAI and .284. I am a big fan of those two powders...particularly RL23.

    Temp stability is nothing short of first class.

    I use both RL16 and RL23 in my 1K rifles and have found them to be very temp. stable as well.

    I live in Arizona where when you traverse the entire year, you can shoot in the low 40s to well over 100 degrees. I used RL-23 in one of my .300WSMs ALL YEAR with excellent results. Temp stability is "off the scale" good!

    R23 is R16 made slower, which is AR Comp made slower.

    Which is the most temp stable powder on the market. By quite a margin. So, all of the Tz powers are crazy temp stable.

    The only other powder that approaches the TZ formula for temp stability is h4350, and it varies from lot to lot.

    I was testing R23 in my 243 yesterday. I got a lot more speed than r16. Same behavior. Lots of small groups and low spreads. Very small scatter nodes. Very flat response.

    It has been very stable in my 6mm Rem.
    It's my go to hunting rifle. It has held hunting accuracy from 12* to 104* for me.

    While I can appreciate your passion for AR Comp, I disagree with your mediated input to it, and see negatives bleeding out from your personal campaign to it. RL23 is not RL16 made slower, it is an origin of RL22 burn rate with technology improvements, just as RL16 is that of RL15 and RL17 burn rates. As is AR Comp, an origin intended to a specific burn rate. There not one made slower or faster to the other, as your implying. They are independently made to specific burn rates with technology improvements over other powders of similar burn rate. Your passion for AR Comp has been repeatedly noted over and over, and very obviously across the forum and active members for sometime already.

    I know the guy that developed all the TZ powders. You can ask him yourself. He posts on here.

    I'm in a place where I'm gonna load some 338 lm with 200/210s for fire forming. I'm using rl23 for this use. Not too concerned now about temp sensitivity but I'll probably use this powder for loading 230 eldx loads this fall. I've had good success with it in my 22-250ai but don't usually use it in cold weather like deer season. Be curious to hear your results

    I’m in S GA and it’s about to get hot. So we will see. So far 54F/68F no difference in speed. Only data I have at this point. Gun and load seem they will hammer. Looks promising so far

    I switched to RL23 from H4831 and it is far more stable than H4831, which isn't bad to begin with. I'm in Nothern CA I can shoot from 35-110 and dont need to adjust my load. Best powder I've found for my 260AI, and I can use H4831 starting data safely. (For my cartridge, this is not a blanket statement, although it is very similar to H4831)

    You are using RL23 in your 6mm rem ?? Care to share info ? I have a very nice OLD 6MM rem 40X.

    Even more mediated input yet, by insinuating: "From the guy that developed those powders for Alliant".
    With that said, I am fully aware of who you are referring to. In years past, have spoken with him on the phone, email & PM exchanges, and conducted tests with RL16 for Alliant before it's public release, that were orchestrated through him directly. Not taking away from Paul's propellant head engineer position at Vista Outdoors, but he is not: ".... the guy that developed those powders for Alliant" as your insinuating.
    Will also suggest to re-read his Q&A email response more thoroughly, for the actual context meanings, and to who it says developed those powders (and technologies). And suggest, to physically look at and compare the actual kernels of each.

    Wow. I never thought H4831 had any temp sensitivity issues. Been using it for decades with zero issues here in northern Mi. Used in well below zero thru well above 90 with excellent results throughout the temp ranges. Can't imagine any powder being more temp insensitive.

    My tests produced a curve which is a fairly flat slope from 0F to 90F. After 90F the curve sharpened. From 0-130F ammo temp (these are not ambient air temps but ammo temps) the span was ~50fps on a charge weight of 45 grains in a 6mm bore 26" long. It was as stable as H4350 if not a little better. That is a single test. I have other test data sets on it but I'm not really wanting to dig through my records to find them. In the middle of the temp range, from 50-80F the noise in the numbers was greater than the signal.

    What works in my rifle is 100 gr. Nosler Partition, 46.6 gr. RL23, Nosler brass.
