Thread: Belmont rifle powder 763

@Pommy
Yep, downloaded Gordons Reloading Tool the other day after reading about it on the Oz F Class Forum . Yet to have a good play with it but from reviews it looks like providing a good (free) alternative to QuickLoad, once developed a bit more.

Burn rate equivalent charts need to be viewed with caution. Print out several versions and they don't all agree - albeit minor order changes. To be used as a guide only methinks..... Some charts put PP 2000 close to Rel 15. Whilst Alliant themselves list it between Rel 16 and Rel 17.

Because WW760 is seemingly a slower powder than PP 2000 I would be reluctant to use 760 as the equivalent. Problem with WW powders is there are relatively few different types so powder equivalent charts will show lots of overlap with other brands.

Has anyone actually contacted Belmont and put the screws on them for some definitive I've data? If they sell the product they should also provide guidance.

I did a gogle with it and found a data sheet Read the first part closely it appears to bracket (763 ) with being the same as power pro 2000.

I would still like a bit more information ( hard data ) before changing to it and getting 10 KG nSeems it may have temp sensitive characteristics as well. I might stick to ADI 8208 its a bit spendy but meters as well as ball powder.

How did you get on @Marty Henry?

Also I found this on the Belmont website under Reloading Data, same tab as the powder section.

So here is a reply from Belmont in regards to 763. Leaves me wondering why they are selling it at all. Hardly reflects much understanding or confidence in a product they are selling.

Question:

Hello,

Simple question before I order bulk 763 powder off you:

Is this powder the same as or interchangeable with Alliant PowerPro 2000-MR?
If not, is it similar in its performance?

Thanks

Reply:

There isn’t a lot of data out for there for this relatively new Powder. The 763 has slower a burn rate and is suited to heavier bullets above 150gr

Kind Regards

This hardly instills confidence to try it, so I won't.

Sounds like they copied a blurb. Fuck it. Here's the data I've collected...

31.7gr, 2433, very sooty
32.0gr, 2484... less sooty

Yo @Pommy - ya forgot to tell the rest of the team what calibre this is!

It's his 6.5 Grendel for anyone who's interested. That 120 Sierra softpoint load is stunning from a 20" barreled mini cartridge. Those 4 rounds at 33 to 34.5 grouped at about 15mm. Very promising!

Tbose are good numbers from the Grendel, and the 308 to be honest.

There w748 and w760 are brilliant and CHEAP. Lol

I might have a few cans going spare now

The answer I received was pretty much the same as what tahr got and they would not confirm if they put it in any of their loaded ammunition. Basically seemed to be you try it and let us know how it goes.
Thank you @Pommy I'll start tinkering with it in a 3006 and 9.3 soon and let our know how it goes.

Just to update on an oldish thread.... as always results may vary in your rifle work up slow Bla bla be warned

Just finished a short test of W763 powder as sold by Belmont. I did a heck of a lot of reading up on the webnet about Alliant power Pro 2000MR.
My own conclusion was that they are very likely the same powder.
( as a side note a lot of people were saying PP2000 is the same as CFE223.... NO its isnt an Alliant rep actually got on line and shot this one down in an old thread some where from 2017 )

I shot these loads over a "chrony F1" not everyones favorite but none the less a comparative test.
Using a .308
This was shot out of my 32 inch barrel using a Barnard action. I also used Lapua S P brass .
I only shot 3 shots of each weight but it gave some basic results and that was all I was after at this stage before pursuing it further.
All projectiles were 155 grain HBC optimas

Reference load AR8208 Av FPS 3071 From a Labradar I get 2990 fps (iirc)

PP2000MR 49.5 grains AV FPS 2979

" " 50.5 grains AV FPS 3028

" " 51.5 grains AV FPS 3106

No pressure signs on primers ( but you hardly expect that with small primer brass ). No heavy bolt lift, all cases extracted easily, measured case bases today no discernable difference across all loads.

Interesting. I have read that Power Pro Varmint behaves in a similar manner in 223, as in loading really heavy charges and getting crazy velocity and no pressure signs - in the range of 2900fps with a 75gr bullet from a 20" barrel. I'd like to try some.
