As per title really. Intended use would be 243 and a 284.

Yup have used their 760 in 6.5 CM and .308
Are Belmont powders basically Winchester powders rebadged?
IIRC they are St Marks ball powders, https://www.gd-ots.com/propellant-an...r-propellants/Quote:

I think the action rifle is st marks. And win 760 and 743 are bulk powders with slightly different burn rates.Quote:

I would like to try the St Marks 763 stuff they have but theres not a lot of data to go on.
Anybody tried it
I did some research and I think that 763 might be the same thing as Alliant Power Pro 2000MR. Obviously you would want to know for sure.
Thats what the man at Belomnt told me. He said look at the winchester 760 load data for the belmont 760 load data........... And of course looking up the Win 760 load data takes to straight to the Hogdon site as they are the same.Quote:

then loaded some 125gr SST seated to the cantilure their max load on their load data chart for 130gr projectiles is 46.2gr so loaded 46.5 @2852 FPS-47GR@2885 FPS-48gr@2975 FPS on my basic coronagraph in summery I think I will go back to AR2208 for projectiles above 150gr and use that powder for my 204 as well but still use action rifle for 150gr downwards
I've had a play with it in my 6.5 Creedmoor. As @Beavis said, my research showed that SMP763 is sold by Alliant as Power Pro MR2000. I found an SDS (MSDS) that specifically referenced this - it may even have been on the Alliant page for MR2000. But definitely check for yourself.Quote:

I've been experimenting with 48 grains and changing seating depth - kind of an odd thing to do when the projectile has a large jump to the lands. Turns out it can still make a difference.
What projectiles does it go well with in the 308?Quote:

760 is really too slow for lighter .308 loads. Stick with 748 or 747
I've had good results with their 747 powder in the .223, no complaints at all. Not used any of their powders in the larger calibres but over the years I've used a lot of their factory ammo in .243 and 7mm08 calibres and never had a single issue.
I have to say that above all else, I've enjoyed excellent customer service from Belmont over the last 30 years. Their deliveries have been efficient and reasonably priced, they often have good deals and they have experienced staff available to answer questions.
