Anyone shooting IMR4895, and how do you like it compared with H4895? I have a chance to pick up 6lbs for around $15/lb, and plan on loading behind 168s in my .308 and 75-77gr bullets in my .223. I have had good success with H4895, but haven't tried the IMR flavor. Thanks!

Re: IMR4895 vs H4895?

I have used several JUGS of IMR 4895. It's a good powder.

If you look at the burn rate charts they are listed as the same, or very close. It all depends on who's burn rate chart you look at. Some people say you can use them interchangably. But I would drop a grain or two and work back up to be sure. At the very least, I would test it as a different lot number.

When you finish the tests let us know what you found.

EDITED TO ADD: For a long time Hogdgon powder wasn't available in this area. That's why some of my data is dated in that manner. Also why I tend to favor IMR slightly. Most of that was available just driving into Knoxville, (25 miles).

Good luck.
 
Re: IMR4895 vs H4895?

In the lots I had, I was able to use H 4895 with the Same Data, and got identical FPS, but higher ES with the H.
 
Re: IMR4895 vs H4895?

some testing has revealed similar but not same results...

consider working up loads with both to avoid mistakes of interchanging based upon others findings...

a blow'd up face can make for a bad day...
 
Re: IMR4895 vs H4895?

Never tried H4895, but IMR 4895 is the shizzle. Really though I've had some pretty positive results with 40.5g IMR4895 (yeah it's low but it was a sweet spot) and 168 A-max's.
 
Re: IMR4895 vs H4895?

I have used both at times different weights but good groups with either.

Good luck

LC brass and IMR 41.5 4895 OR H4895 with 168 SMK is the M852 loading... it works great and, I load it all the time for my M1A. It's the perfect combo.
 
Re: IMR4895 vs H4895?

Thanks for the info. I have a good selection of Varget, H4895, IMR4895, and TAC, so I should be able to find a good load with 168 and 77gr bullets.
 
Re: IMR4895 vs H4895?

I have reloaded with both as well and also found H4895 to be slightly faster in FPS.

The Hodgedon Extreme powders are less temperature sensative!
 
Re: IMR4895 vs H4895?

Hello all,

While we're talking about 4895, I have a few kegs of RG (Radway Green) 4895 pulldown powder that I haven't gotten around to yet, does anyone have any experience with it?
 
Re: IMR4895 vs H4895?

I just loaded for my .300 win mag IMR 4895 - 61.9 gr with a 168 Hornady match....I looked it up on IMR's website and the have H4895 load max at 59 grs. Should disassemble and start over with a lower load? Please advise. Thanks.
 
Re: IMR4895 vs H4895?

4350 is about as fast as I would go in a 300 Win. Get some 190's or heavier (210 is my preferred) 4350/4831.......... use the 4895 for the 308.
 
Re: IMR4895 vs H4895?

Yeah, 4895 does seem a little fast for a .300 WM...

How could we know, without having your rifle. Start low and work up. Look for pressure signs.
 
Re: IMR4895 vs H4895?

Well, what I was looking for is weather or not my starting point is too high for this grain bullet. I have not found IMR4895 powder with a 168 Hornady Match bullet combo.
 
Re: IMR4895 vs H4895?

I got more total speed before pressure signs out of the IMR, but the H4895 was much less temperature sensitive. They are NOT the same powder, just live in the same burn rate neighborhood.
 
Re: IMR4895 vs H4895?

Equal loads will be running a little slower with IMR over H 4895, but at a lower pressure.

 
Anyone have some updated information on this? Currently shooting a 6bra with H4895 and cant find any. I can find IMR 4895

Your H4895 is 94 on the burn chart, IMR4895 is 96 on the burn chart. I've got one pound of the IMR I was going to use. But until I've got more of it I don't want to do load development on 1lbs of powder (308).
I think you would be fine to develop loads with the IMR. Maybe some one with QL can chim in with some numbers.
I do believe it is alittle more temp sensitive then some other powders from my reading.

According to Lee they have the same volume measure of density, so take that for what it is worth.
