IMR 4320 in 6.5x47L???

[areaone]

Anyone tried it, seems like it could work. RL 15 is burning dirty in my Bartlein. using lighter bullets(under 130) any help is appreciated. Imr4320 works great in my 22 250 with any bullet 55-75 gr, just a thought on the 47L.

It's in the right area burn rate wise for the lighter bullets. Let us know how it works out.

I know this is an older post, however...i did a load work up this past weekend using my 6.5x47 Lapua. 28" ,1:8 ,1.25" no contour Krieger on a blueprinted Remington 700. I shot 37, 37.2, 37.4 and 37.6 grains of IMR4320 under a 140 grain Hrn ELD M. 37.2 was the best grouping at 100 yrds. Average velocity was 2790 fps. I shot 15 rounds and produced a hole within a nickel.

Enjoy whatever IMR4320 you have, it's been discontinued. There's still some in the pipeline out there though.

I have 2 8lb jugs stashed somewhere.

When a great powder gets discontinued because it's not selling,... makes me realize we have almost too many good powders at our disposal.

Marketing works. Everyone is convinced the old powders don't work as good as the new powders. IMR has produced the best accuracy in every gun I have ever owned. Every. Last. One.

When my 6.5x47 comes (can't wait for the beginning of June!), I've got plenty of 4895, 4064, 4320, and 4350 which will all be given a fair chance and I imagine one of them will impress!

This news sucks.....why do they have to meddle with something good?

I don't know how true this is.

I have not seen any mention of imr-4320 getting discontinued until @1lnbrdg mentioned it.

It's still on the IMR website and a few days ago there was a bulletin article about how good IMR-4320 is.

This is the second time that IMR 4320 has been discontinued.

Sent an email off to IMR about 4320 a while back and they confirmed it was discontinued.

Even though it’s a bit faster burn rate, IMR4166 is what I believe to be the “replacement” for it.

That is odd. Isn't 4166 closer to 4064 speed?

Yep, as I said even though it’s a tick faster.

They, 4166 and 4320 seem quite similar in performance.

4166 looks much more like 4320 in regards to kernel size.

Not interchangeable by any means but my theory is that’s what IMR was doing

Yea, back in the 70's i tried to use 4064 in Everthing ,seemed to work well.
