Request for Kernels dimension for these powders

[Jicko]

If you have any of these powders on your reloading bench, can you PLEASE help me out?

Vihtavuori N530
IMR 3031
Accurate 2015
Vihtavuori N133
Norma 201

Can you please measure the length of a few kernels and post them here or PM me? Basically, I want to know the average length of them. I am in a reverse engineering project.

Can you also take a picture of a few kernels?

Looking for something that is "longer than" varget... heh hee...

And pics would be good...

Re: Request for Kernels dimension for these powders

The inquiries I made said that N130, N530 and AA2015 are all short cut so that they meter well for the benchrest shooters. All are much shorter than Varget.

Still waiting to hear back about N201...

How about
IMR 3031
Norma 201
?

IMR3031 matches the physical description... at this point, it is worth trying it to see if that is the powder in question.

Norma distributor tells me that N201 is "a little bit longer than Varget... but not much"...

Re: Request for Kernels dimension for these powders

I also found out that 3031 seems to fit the physical description, I just have never seen 3031 being used for 175gr .308

But I guess, the general wisdom would be using more than just 40gr of powder for 175grainers.

So.... now.... IMR 3031 and Norma 201 would be the potential test candidates...

Any intel on whether the powder being used in the new and improved load is truly canister-grade, or just a bulk lot version of the same stuff?

I would expect +/- 5% on charge weights to get the desired speed if NOT canister grade...but that's merely a poorly-informed estimate two steps away from a WAG.

Re: Request for Kernels dimension for these powders

It was implied that it was bulk...

Velocity just needs to be close to what was posted, not exact. Temperature stability and muzzle flash will be better indicators of whether it is the right powder or not. Heavy neck tension will probably be required to better simulate the load and help get the velocity up. Its a military load, so it isn't going to be light in the neck tension department.
