16, 23 and 26 are new and awesome. I've ran 16 in 7mm-08ai and 23 in a 6mm creed. Both were extremely temp stable. Ran pretty much the same test on both by storing 10rds in freezer (16°) for a day and 10rds at heater temp (roughly 108°) temp spread was around 10fps for both powders across a magneto speed v3 chrono.
I'VE pretty much decided I can reload everything I own, using Unique and either of the 4895 powders (an epiphany which did not visit me until AFTER I became the proud owner of 13 different propellants. Long story). If these were unavailable, I would try to locate Herco and IMR-4064. Each of these is a slower-burning, but otherwise similar propellant to the 1st 2 I named. I'm also sure that there are similar and perfectly satisfactory propellants sold by other manufacturers which would fill each role nicely (AA-2495 and AA#5 come to mind). For some reason, though, I usually end up using Hercules/Alliant propellants in sidearms and IMR/Hodgdon propellants in rifles. I also like Hodgdon Varget for everything I shoot.
No rifle I shoot is chambered in a terribly over-bore caliber, so the 4895s work splendidly in all of them. In the interest of leaning toward the "Super High Velocity Meat Homogenizer" class of calibers (perhaps in the future), I could get slightly better results from them with IMR-4064 than with the 4895s. Perhaps not optimal, but probably better than with the 4895s.
Except for the understanding that 4350 seems to work very well in 6.5 Creedmore, I am essentially clueless about both cartridge and propellant. If I could find data nowhere else, I'd try to find a recent copy of Cartridges of the World & see if they have any recommendations.

Good info here.
Temp tested my .308 loads with IMR 4895 over the weekend.
Left a few rounds in the ice chest until ready to shoot, others were in the cab of the truck. Had about 15fps variation from ice water temp to 75 degrees or so IIRC.
Standard deviation for was much lower with the cold ammo, but it was a small sample size.

If you remember we did the same with my 6.5 Creedmoor rounds loaded with H4350. No velocity or SD change at all. I was impressed with it.
Either? I was under the impression that we might encounter at least 4 4895s - H4895, IMR4895, AA2495, and bulk/surplus/old 4895 (no prefix).
Don't forget pistols. I have several pistols that just love H4895.
Of course, they're chambered in 6.5BR, 7x47, and .308, but still...
Done
The only two rifle powders designated 4895 with which I'M familiar are IMR-4895 and H4895. The AA2495 may be some equivalent of IMR-4895 or H4895, but since it is designated AA2495, and NOT AA4895, I intentionally omitted it from the conversation. I don't think I have ever seen, nor even know anyone who has used "bulk/surplus/old 4895 (no prefix)". Having no experience with the latter 2 powders you mention, I am hesitant to make any firm judgement as to whether they are as versatile as the TWO 4895s with which I AM more than passingly familiar.
I don't mind being quoted, but I would appreciate being quoted without substantial alteration to the original sentence and in entirety, thus:
Found my pics of testing reloader 16. Keep in mind these aren't full blown load development loads giving the higher es/sd but still usable info. Barrel was cooled (included pic of proprietary cooling method lol) in between strings to give somewhat of a fair shake. Rounds were fired pretty much as fast as possible.
Thirdgenshooting just got some in stock recently.
Uh, no. Not a chance.
Excessive quoting is a violation of good net etiquette. On many forums, doing so is such an egregious violation of standard communication protocols that it can result in expulsion.
I will not be rude to all the other members of this forum in order to indulge the desire of one member to be quoted in full.
God knows, if people quoted me in full back when I was a regular poster, the length of certain sub-forums would have been doubled. Nobody needs that.
I didn't say you had to repost everything I said, but kindly do not take fragments from a sentence and splice them together without the original words in between. It almost always blurs context, can often alter meaning, and may be viewed as a willful and malicious representation of the original prose. I know an excellent way to settle this issue. In future, please do not quote me at all.
Even with the "please" that is rude.
