What to do with my IMR Enduron 4451

[jps24]

I have 8lbs of IMR Enduron 4451 that I've never used. If I recall correctly, it was supposed to be temperature stable similar to H4350, right?

Anyways, just wondering if anyone has used this powder and recall any pros/cons? I reload for 6.5CM and 25x47 Lapua if I could use IMR 4451 as a back up to my H4350?

It works well enough in 6.5 CM . I know a couple of people who use it and seems pretty consistent not the fastest Fps but accurate enough. Best thing is You've got it so use it .

I used 16 lbs. of the stuff when H4350 was really hard to get. My load with Hornady brass, Hornady 140 ELDM, CCI BR2, 41.8 grs. of IMR 4451. gave around 2700fps in a 24" Bartlein and very good SD. It is temp stable. No cons that i can think of its pretty good in 6.5CM.
