I then used the Prometheus Gen II Powder Scale to throw all charges. I've checked the Prometheus several periods on the substantial-end Sartorius analytical scale, and each time it confirms what I presently know: the Prometheus is exact right down to a single kernel of powder! The Prometheus isn’t low cost (starts off all over $three,800), but if you reload approximately I do, it can save a bunch of time, and lets me to Visit the variety in lieu of sitting all over loading all day long.
For example, this blog site about impact of temperature on powder and the specter of a temperature impact on the primer. Another example, the put up about probable outcomes from barrel and bullet have different coefficients of linear thermal expansion. Most appealing but all the consequences at this amount feed into the merged impact on shorter assortment precision, necessarily mean muzzle velocity and muzzle velocity SD.
White Hots are clear burning, so cleansing concerning photographs isn't needed. Right after capturing, a damp patch eliminates nearly all residue and does not have any rotten egg smell or residual scent.
Many thanks with the screening, I exploit H-one thousand a good deal, I wonder whether it is equally as steady because it’s also a Hodgedon Severe powder. Wonderful write-up
Possibly they can't even do that now. It would make clear why finding a large amount of those powders has been incredibly hard the previous few months while some coming from Australia and Europe are still demonstrating up listed here and there.

I’ve experimented with “improving upon” Berger bullets by pointing them and excess weight sorting them, however it experienced pretty much no impact on my teams downrange.
Our exams validate which the Enduron powders are as unaffected by temperature as any powder could possibly be. If you are a reloader therefore you shoot in a wide range of ambient temperatures, you owe it to on your own to test these IMR Enduron powders.
Consequently, we picked 5 unique rifle calibers to test all a few powders concurrently. This turned out to generally be a bigger process than we experienced at first envisioned, imr enduron powders but the results have been worthy of the trouble.
They recommend you location the Doppler beside the rifle, and it looks like they may account for that offset because they interpret the final results and correct for it. The center of your gadget is generally lower than twelve″ with the barrel, which isn’t A lot once you’re referring to measurements taken fifty-80 yards down variety.
That is a wonderful issue, Martin! I hadn’t thought of that, however, you’re Totally ideal. There's some value to some powder have a predictable, linear change in muzzle velocity.
It will probably be fascinating to view if any of The brand new RL powders start finding some detect and use. RL16,23 and 26 are imagined to be temperature steady.
AR2209 and AR2208 are in fact the exact same powder. You are able to prove this by investigating the MSDS datasheets to the Hodgdon internet site. The organization is definitely now owned with the imr 7977 in stock French Thales. I have just viewed Varget and H1000 switch up right here (Europe) for The 1st time in several yrs.
You didn’t protect the issue on the rifle through these exams. Although the powder may be at a selected temperature since it’s placed into the feed ramp, it’s pretty not easy to forecast what the temperature of the load will be all through the imr enduron powders moment of firing – esp. if it’s been sitting down from the chamber for more than a few seconds – brass will perform most current warmth promptly.
