Default New Powders From IMR

Just saw this posted from Powder Valley. IMR is realeasing 3 new powders: IMR4166, IMR4451, and IMR7977. Here is the website link: imrpowder.com/press.html It appears that they are all intended for rifle applications.

Powder Valley has some 1# & 8# jugs of the new IMR4166 in-stock, if you enjoy trying new powders.

I just started reloading 308 last month, just got some 30 06 dies for playing with this winter and have 7mm Rem mag dies on my list.

Soooo, I have to get all 3 powders?

happy hunting, and hope you find some to play with

66 & 51 are kissing cousins to 4064 and 4350 for what
I use in the 270 and 30-06, just looking at their data.

Can't wait to see how it does in test when used in the days ahead.

I'd be nice if they could make some pistol powder, new or old, for us too!

I live in northern Colorado and powders are still very difficult to find in this area, at least at a price near normal retail. It bothers me that companies come out with new products when they cannot keep up with current products. So now we have 3 new unavailable powders available or would that be 3 new available powders that are unavailable......or something to that affect.....

From the IMR "News" section... "...sophisticated extruded powders that are loaded with more features than any other brand of powder available today."
So... new and improved. Better than anything else. But, you can't actually buy it. The folks at IMR have attended the same marketing school with the folks from Microsoft and Apple.

No, actually that is three new powders being made, packaged
and stored...............

while we are all waiting for the old line of products that we use
to be made, packaged and shipped at some point, to dealers
where we might be able to buy it, before it is sold out.

Don't you just love it !!

...for reduced loads. FUN!


I have seen more rifle powder than anything. Surely something on the shelves will work for a while.

Default For being discontinued.......

I heard IMR 4759 was discontinued, but there was plenty on the LGS shelves today.

The price on the IMR stuff was like $29/lb though.

Look on IMR website, data, rifle, cartridge, bullet weight, type of powder and it pops right up. And yeah, it does look like a good powder for .308, which means it's also probably a good powder for my 30-06.

For the last year I have ben buying the discontinued powders so have enough of most except for PB..but I really haven't used it much in the last 4 or so years. Just had a friend give me 6 pounds of 4759 in an 8 lb can. The only powder he was loading..cast bullet rifle shooter. After the new powders get in top production...I wonder what other powders they will discontinue in the IMR line?? You know it's gonna happen!!

Looked at load data for the new stuff & I fail to see that it'll do anything the old standbys won't or can't do . Thank God I've enough 4895 , 4064 & 4350 to last me rest of my life . I'd like to get some Reloader 22 for my 6.5X55AI , but might have to settle for kissing cousin Norma MRP .

IMR's new Enduron powders have been out for months. Available most everywhere and locally. They're pushing the new IMR powders and making it plentiful. Hodgdon's on-line site has data for all the new IMR powder plus they have the data in their 2015 and 2016 Annual Manual plus some articles and testing of the new powder.

Actually, there are FOUR new Enduron powders - add IMR4955 to the list. It falls between 4451 and 7977 in burning rate.

Don't knock those new powders until you try them. They produce some of the smallest muzzle velocity deviations I've seen in 40+ years of handloading. That contributes to accuracy and I've shot numerous one-ragged-hole groups with 4451 in two rifles and two of the other ones are just as good (haven't tried 4955 yet).

One drawback is that when loaded for top accuracy, muzzle velocity is down a bit from older powders but if you're shooting targets, that's not a concern and even if you are hunting with them, the drop isn't significant. My Remington 700BDL in .260 REM, for example, shot groups of 0.507" and 0.496" at 2,715 fps using 42.0 grains of 4451 under a 120-grain Nosler Ballistic Tip with velocity deviations of just 8 and 14 fps. That represents about 1/4-inch tighter groups at the expense of about 80 fps of muzzle velocity. If I had more scope magnification on that rifle, I know the groups would shrink some more.

My heavy bench/varmint rifle in 6.5-284 Norma has shot some groups as small as 0.180" with 4451 under a 140-grain Berger VLD. The stuff really works well and at least in these parts, all those Enduron powders are and have been in good supply.

I read some speculation above about more Hodgdon/IMR/Winchester powders being discontinued. When the discontinuance of several powders was announced about a year and a half ago, I spoke with Hodgdon's about it, as they were axing two of my favrorites, IMR SR4756 and even the fairly new IMR 4007SSC.

I was told that there are two methods of producing gunpowder and the newer method takes one-third the man-hours of the older method so one by one, powders were switched over to the new method. The trouble was that numerous powders could not be made that way and were becoming money-losing propositions, so the ones that weren't setting the sales world on fire were dropped.

Given that, it would seem safe to speculate that any powder that remains in production will continue to be made as long as it is profitable for them to make it.

If one of the discontinued powders is a favorite of yours, commence beating the bushes for what remains on gun shop shelves. Between my own shopping and the help of two members of this forum, I accumulated 15 pounds of SR4756. And by just looking for it, I found four pounds of 4007SSC so the stuff is out there. Small gun shops are your best bet - the "big box" sporting goods stores are where everyone shops, so their supply is long gone. For example, I know where two eight-pound jugs of PB are resting comfortably in plain view on a dealer's shelf. If I still shot trap competitively, they would not be there.

rg1, AveragEd, if you look at the dates on this thread, you will see it first posted in 2014 and was necroed yesterday by a newby named "billfitz". This "billfitz" guy actually has made only 2 posts total on the forums and both were thread necroes from 2014. So that is why the stuff posted in this thread and the other one seems a bit dated.

Interesting read about the new powders . While I still shoot 2700 , I no longer compete in rifle events with the exception of cast bullet service rifle @ my local club . Rest of my rifles are for hunting & the thought of new load developement / costs of bullets makes my head hurt . If one competes then as stated above a ballistically stable load will insure smaller group size , especially past 200yds .
