Discontinued: IMR Enduron powders.

[GRG]

I really liked 4166 and 4451 but I have also moved on. At the price of Hodgdon/IMR powders I wont be going back even if they become available.

Yup, I have a couple of pet loads with 4350 and 4895 that I may buy more for, but I have a hard time shelling out 60 a pound for any powder... I'm thinking of developing a few loads for the mil surp powder I have on hand and burning that up while the market normalizes a bit. I don't think prices will go down much though without more competition.

I believe the price of powder will come down when we stop supplying it to waring nations. Genral Dynamics is a large supplier and that is where the Enduron line is manufactured.

I've got 5 lbs of IMR 7977 if anyone is interested, make you a deal .
I too loved imr8133 in my 264win mag, single digit ExSpreads into 1/4" groups with 156 eols.

They were IMRs only double based powders that I know of. I had amazing results with IMR-4166 but it hasn't been around in a long time and I've moved on.

I have all of the Enduron powders in stock but never got around to testing them in my different weapons due to the fact that I was so interested in the Hammer Bullets and their performance ,as we all know, we needed faster for caliber and weight powder than for cup and core bullets. I will probably test the Enduron powders with the 30 an 28 calibers with the Federal Terminal Ascent bullets , which in my humble estimation and limited experience is a wonderfully designed projectile . It performs, has been easy to make accurate and has been a devastating performing projectile. These are loaded a little on the light side due to them creating more pressure because the shank is solid copper, I use the Barnes loading data as a starting point for them. JMHO

I have found IMR 4955 to be one of the worst powders I have tested. The burn rate from lot to lot was very inconsistent, like the burn rate ranged from 4350 to 4831. Blew primers in 280AI and 25-06 loads using Hodgdon starting loads...

I tested a lot with the Hammers during the Enduron lines existence. As @JakeWes said, I also found 4955 to be eratic. I had decent results with 4451 but nothing like 4166. 4166 being the faster burn shot under .5 and mainly under .2 with every light Hammer I tested in 6mm, 7mm, 338, and 9.3. I also found the hammers to have LESS pressure than other copper bullets mainly due to the much reduce bore contact even compared to C&C bullets. Dont baby em. The AH hammers have the least bore contact of all, being a bore rider bullet and often produced 200 fps more speed than any other copper or C&C bullet. I also found that IMR-4451 was quite temp sensitive. YMMV

4955 can be erratic! But I got a deal on a big jug I couldn't refuse haha. Just not a powder you use to try to find the redline with that's for sure. But I have a nice boring 300 win mag load that likes it with 195 TMKS at moderate velocity.

I have found it's a powder that goes from zero pressure signs to stiff bolt and cratered primers in as little as 1 grain increase in the 300 magnum. So I just stay conservative with it now, but it's not a bad powder. I've changed my tune about it
