IMR 4451 in a .308

[wboggs]

How is IMR 4451 for loading a .308 155-185 bullets?

Unless you have a good supply of it I wouldnt waste time working up loads. Enduron powders are no longer made. I had good luck with 4451 but still like 4064 better.

My local shop has an 8# jug of it at a decent price, I've been considering it as well.

Sierra’s new manual shows the imr 4166 powder a lot for the .308 and not the 4451.

ggshoots says Enduron powders are no longer made.
That kinda makes sustained use impossible

4451 is about same burn rate as H4350 so a little slow for a .308. The 4166 is a better powder as mentioned. Hodgdon doesn’t list any loads for 4451 and those weight .308.

I had gotten some to try in 7mm-08. Wasn't that impressed with it.
While i had it, tried it in a friends 308 with 168gr bullet.
Velocities were low. Accuracy ok.
Go with the 4166 if you can find some.

I actually used both 4166 and 4451 in 308, they both worked much better in my 243Ackley. I figured while powders are tough to get, going with a newer powder selection would make more sense as it should be more readily available. Spent enough playing with both and working up loads, now I cant find any. I heard it was discontinued so had my dealers check, they verified it was done.

I just loaded some 180 grain ballistic tips for an old '06 using 4451 and it worked very well. I simply used 4350 data and backed off a bit. Don't pass this powder up if you see it at a good price.

I have 8 lbs of 4451. I use it in my 06 ai. Andin my 375 taylor. While I have not tried it in my 308 ar might be worth trying.
