IMR 4895 and Varget

Amazingly close in burn rates and charge weights almost across the board, kind of makes me wonder if the difference is coatings rather than formula.......

I am still out On Varget Vs. H380 for my varmint guns.
It works very good in my 308.
Similarity in burn rate is a response to market demands.
I always figured Varget was closer to IMR 4064 but have not studied the load data lately.
I also find that 4064 generally performs as well as Varget in most applications, though again not all- I'd agree that for H and IMR those two are probably closer.
If you want a head scratcher, some burn rate charts show one right next to the other but others (and not just one as a fluke but a couple) show them a good 10-12 places apart.
Looking at TESTED load data in a variety of cartridges, it is apparent that Varget, the 4895s, and 4064 are kissing cousins. Not twins. In some loads, one is faster or slower than the others, and they all trade places - but are within a grain or less of each other at maximum charge levels.
I'll use my remaining VARGET (I've got about 16 pounds of it!) for my .30-06 when I run out of IMR 4350.
I still like Varget over 4895 for my 308's,. Don't know if it has anything to do with it, But Varget has seemed to cut my flyers down when I have a good string going.

Right on about the IMR4895! I've seen it work miracle groups one day and next day, OMG a flyer quite often!
H4896 seems little more stable, but I try to stay conmpletely away from IMR4895. also seems temperature senstive! It seems too be ok when used for firecrackers, therefore I call it firecracker powder! The 4895 firecrackers also sound louder on a hot day![:I]
