The Fact About IMR 7977 That No One Is Suggesting

Ha! Fascinating position, but I went back and looked at the information. As I discussed in Another responses lately, I shot 5 unique cartridges/hundreds about all 3 of All those chronographs.

I then utilized the Prometheus Gen II Powder Scale to toss all rates. I've checked the Prometheus quite a few occasions with a significant-end Sartorius analytical scale, and every time it confirms what I previously know: the Prometheus is accurate down to a single kernel of powder! The Prometheus isn’t cheap (starts close to $three,800), but in case you reload just as much as I do, it may help you save a ton of time, and makes it possible for me to Visit the vary instead of sitting down about loading all day.

Loading density is great for magnums, nicely filling the situation at greatest rates, contributing to exceptional uniformity and accuracy.

An electronic powder dispenser would also function, if you want to stare in the wall when it will take for good to dribble out the powder.

Additionally they are formulated being temperature insensitive, just like what we’ve seen with Hodgdon’s Extreme series of powders.

The vast majority of our fired range brass is acquired from private, community and law enforcement ranges. It can be then sorted and cleaned in our warehouse.

Wow, Blaine. I could undoubtedly see a alter of price concerning a lot, but the muzzle velocity going down as temperatures go up is one area I haven’t observed. The reasoning is bending my brain a little bit. Can you tell me somewhat more regarding the specifics of when you noticed that?

I two other OCD handloaders which i’m superior close friends with run throughout the same experiment. One of them ended up Using the similar order as me, and I feel the opposite 1 (who was essentially Patrick, the dude who did this powder test) explained the Sellier & Bellot primers produced the bottom SD’s for him, but CCI was correct guiding them.

This will probably do a lot more that will help your shooting and acquire probably the most out within your gear than anything you imr enduron powders are able to do. It just places you over the quickly-observe, and will help you study in a few days what might choose several years if you merely practiced and experimented with to understand every thing by yourself. Here are a few possibilities I understand of:

It truly is possible that no more dialogue is required, wherein situation we suggest starting up a whole new thread. If even so you're feeling your response is required you are able to nonetheless accomplish that.

I brought the IMR 7977 heating blanket into the variety with me, and Enable each of the cases warmth up for 2 several hours as I geared up the test. Yet again, a thermometer was positioned alongside the situations to measure the final temperature.

In order to avoid that state of affairs, when employing imr enduron powders a temperature sensitive powder the wise decision would be to load down therefore you’ll keep on being within the number of safe pressures even when the temperature rises. But once you do this, it possible eliminates any muzzle velocity advantage Individuals powders may have supplied above those who are exclusively formulated for being temperature steady.

AR2209 and AR2208 are certainly precisely the same powder. You can demonstrate this by thinking about the MSDS datasheets over the Hodgdon site. The organization is really now owned with the French Thales. I have just viewed Varget and H1000 switch up listed here (Europe) for the first time in many several years.

As well as pace was averaged in between The 2 chronographs. There is absolutely no way we could know for sure which a person was appropriate, so the most secure guess was only to ordinary them. They ended up very, incredibly shut … so it didn’t really make a difference Considerably.
