The H4198 extreme measures better than the IMR.

H-4198 is pretty much the powder of choice for 30BR competition. I'd save the IMR for fireforming or feed it to your lawn if there's not much of it. :)

Or feed it to your .222 or .223, which will happily gobble it up, unless you only shoot BR.

What about Benchmark?

Benchmark works great. You need 36 grains to get into the 2950 tune window.

Haven't tried it, but I'm told that Rel 7 works well also.

Some lots of Re7 work great. I have a lot that does. It is similar by weight to 4198 but is considerably denser.

I couldnt get enough Bnchmark into a case to even come close to 2950. more like 2650. I dont recall the lot number on my powder jug though. Accuracy was there, just to dam slow!! Lee

Rather than make plant food out of it, send it to me and I'll feed it to my 45-70.
