Does anyone have load data for Bofors RP1 Powder.

[harley1]

Hi, I am looking for some help here! I have access to a good supply of Bofors RP1 powder but I can not find load data for it anywhere. I have found burn rate charts that say it has the same burn rate as powders like Norma 200 for example. (and I have load data for Norma 200) I have loaded Norma 200 for my AR 15 and I have had good results, but similar burn rates is not enough for me as a fairly new re-loader of rifle cartridges ( have reloaded Pistol Cartridges for years) to say to myself it safe to use similar loads.
With all the experience out here I was hoping someone could tell me if they have load data or if they have charts that show Bofors RP 1 to be the same as Reloader 7 for example. I know Bofors has made powders for other powder companies and they have simply re-labeled them as their own powder.

Any help you can give me would be greatly appreciated.

It is a little slower than Vihtavuori N120.
It is too fast a powder for an AR-15 even for the lightest bullets.
Here is a good burn rate chart.

When I can't find load data on a powder I want to use I find data on 2 other powders on either side of it and I extrapolate.
I always start my load development 5% below minimum data and work carefully.
I make sure that the first shot left the barrel and work my way up.
It's not rocket surgery.

Norma 200 was the fastest burning powder in their line of rifle powders.
Exercise great care in using a powder which is generally too fast for the calibre being loaded.
My strong recommendation is to buy a can of powder which you have determined is the proper powder for the calibre you are going to load for. After you have gained considerable experience in reloading, you may want to play with your fast burning powder.
