D4895 vs IMR or H 4895

- Start date
From my understanding, the Dominion powders are not lot-to-lot consistent so every lot number needs a different load work-up. They are more of a manufacturing-grade powder and not a retail-grade powder. So there would be inconsistencies with a side-by-side comparison as well.
In terms of accuracy, if you have a consistent load weight and the powder burns consistently (which it should within the same lot #) it should be accurate. Some rifles like or dislike certain powders so it will depend on the specific burn-rate of the lot # you are using.

The D4064 I got was a 1/2 grain faster then Varget in my 308 accuracy load with 168gr bthp. It was also just as accurate and consistent, it's quality powder made by IMR in Canada, it just won't be the "exact" burn rate as the IMR counterpart, but it will be very close. Might be a bit faster, might be a bit slower, so a chrony and load development will be required to get the maximum load for each lot.
Main thing is that it's good quality. I just got 5lbs of the D4895 to try out, have some 150's loaded up in the 308 waiting for the range. It's quite a fluffy powder, starting loads were almost compressed with the 150's for example.

Basically,what Hitzy said
Hodgdon and IMR 4895 have always been so close that their data has basically been interchangeable.
If you use 4895 powders, then buy a bunch of the D4895, and work up a load for it. It's not going to be any more or less accurate than IMR 4895 you buy in a can, but your load might be slightly different. If you shoot lots of 4895, buy many pounds so you don't need to work up loads often.

All 4895 powders are very forgiving. They were designed that way.
I don't find the D4895 to be any more inconsistent between lots than any other brand. It is a bit faster than other brands from my notes.
It is temperature sensitive. I always use magnum primers to help keep it consistent.
Good powder for the price. I picked up 25 pounds and shared it with a couple of friends. We blended it all together into one big lot and repackaged it after to save space on the shelf.

That might explain my experience with some inconsistency. I was out shooting groups and would seem to get an occasional flier that would just drop six inches. The groups seemed to tighten up as I got closer to Max load. It was probably minus ten or colder though.

I just ran out of the IMR and am looking at the C-A's supply of 5 lbs of D4895. It's like half the price!
Gonna be using it from -40 - +40C conditions in varying humidity. So far IMR and Hodg has had pretty good loading but feel like I should ask here what people's experiences have been using D4895, especially considering the price break.

Like it says on CanAmmo, work up your loads and go from there. You don't say how much you shoot or how long a 5lb jug will last you.
It's good powder, if you do your part. It likes to be in full cases and it likes magnum primers. If you're going to shoot the conditions you describe, close to max loads, with magnum primers is the way to go IMHO

I have 10 lbs of D4895 and 1lb of H4895 I use for reference. I usually load up a bunch of matching loads at low med and high velocity then chrono them and use the data to tune quick load for the new D4895 burn rate. From that point on quick load seems pretty accurate when simulating any of their loads.
I’ll post back when I have a good comparison.
I can say that so far I’m loving it. Getting 1/2” groups at 50 yds in my indoor range with just bulk home cast bullets in 308 that are cookin at 2150 FPS and a beautiful shiny bore after!

CanAm is using a pretty standard warning with this powder. With the 5 jugs we bought from him, I would say it's about 5% faster than than H4895 and very close to the original 4895 from WWII that Hogdon used to sell in the 50 pound paper drums for $15, if you bought 5 drums. That was over 60 years ago and a substantial outlay of cash at that time. About the same rate as CanAms price today IMHO.
When Hogdons ran out of the surplus powder and started bring in new production powder, their new recipe was a tad slower than the surplus powder.
We're actually very spoiled today with off the shelf canister powders and primers. They are far more consistent between lots than they were even ten years ago.
I don't know where CanAm is getting this powder from. I don't know if he can afford to have batches made up especially for his sales. I doubt it. Likely it's overrun powder or he's purchasing large quantities with other dealers in the US and Canada.
Ganderite would know more about that.

It's made in Canada by IMR, all their D###x powders are. I don't know any other shop selling OEM grade IMR, so it seems exclusive.
They also have their own line of ammo loaded for them, so it may just be over run from that.
Anyone can buy powder directly from a powder manufacturer. All you need is a ammo manufacturing licence (the last one I had was 10 or 15 years ago - and cost $400).
Then you have to offer to buy enough that the manufacturer will talk to you. They will start the conversation with "How many containers a year?
By "container" the mean "sea can".
Failing that, you have to find some other angle for them to even answer the phone for you.
I know nothing about the Canada Ammo deal with IMR. I am guessing they bought a fair quantity of powder for their own loading operations and bought extra so it can be sold.
They probably had to promise not to market it as "IMR" powder. It probably is not a canister grade powder. i.e. slightly different than IMR4895.
For this reason, (and because it is cheap) you should stock up with many jugs of it. That way your loading data is good for a long time.
And, unlike gold, powder never goes down in value.

OK, I know it's been a long time, but I worked up some plinking loads for my modified M305. I was using a powder-thrower and was crunching kernels, so maybe my powder weights were less than consistent. Everything cycled fine, no pressure signs. Can't say too much about accuracy, as I was only shooting at 50 yds, but 41 grains was one jagged hole.

I have only used the 4198 knockoff but I redeveloped my light cast bullet load for my Jungle Carbine and the data read almost exactly as I got from the IMR I was using. It was actually impressive how close they were...
