Thread: Swiss RS40 Powder

  1. #1

    Swiss RS40 Powder

    Hello
    Has anyone on SD tried a Swiss made Powder RS40?
    I can't find a single load for .223 anywhere on the internet despite the fact that it is recommended for.223 and .222
    It has been suggested to me that it has similar properties to N133 - any suggestions anyone?
    Thanks
    Ed

    Interesting, can find the site and the fact it's recommended for 223 but no data for that calibre.

    Regards Jim.

    will search some more

    Thanks Jim - Just noticed an update for 'Quickload' on the website - just 125 to find out then !
    The loads on the web page were only for 62 and 69 grain bullets and it took me a while to find them
    Perhaps I ought to contact the manufacturers directly
    Thanks for your efforts

    I just pulled the data file into QL to compare it to N133 and it seems to be consistently 20fps faster but with the same max charge (around 23.5grn for a 60grn VMax).

    From different comparisons it looks like it sits between N130 and N133 speed wise, but it's not as fast as H322.

    Remember that this is only from my playing with the numbers and not based on anything else.

    To dig up an elderly thread:

    Has anyone any experience of this stuff with a 52gr bullet in .223?

    Since I started this thread an experienced acquaintance sent me a load for 55grain Blitzkings which I have tried and work quite well for me - he suggests 24.5 grains of RS40 can't find anything for 52 grain though

    Good morning ED, We have have been using RS40 for about six months. The burn rate is very close to Vit N530. It is a great powder for 223 /222 and 20 tac. I think I have 30 kg on the shelf. If you pm us with your component details we can give you the data you need .
    Yours respectfully Mike Norris Brock and Norris Custom Rifles

    Direct from the Manufacturers: 52 gr Sierra HPBT Matchking #1410: 22.6gr Start Load, 24.6 gr Max Load.

    Additionally:

    Direct from the manufacturers: 55gr Hornady 55gr SP #2265: 22.3gr Start Load, 24.2gr Max Load.

    There is a lot more data available for these loads if required.

    Do tell - "manufacturers" - Is this Nitrochemie AG?
    Where exactly is this info published?
    Where do we look for the "a lot more data for these loads" that you mention? - It is required!
    I want to start using this powder & would like some creditable data (preferably from Nitrochemie) before I put my tin hat on & pull the trigger on some reloads filled with it!

    Ian

    p.s. Thanks to those who have posted their data - It is all good background worth considering.
    I'll be writing to Mike Norris when he is back from the Kelso Fair to get his input for my specific bullet/case/primer combinations.
