    The book shows both (Dasher) can be used but I bought both to try so which would be the better choice. The N140 is real close to Varget and the N540 is slower. Picked up some Berger 108gr BT's to give them a try. Vacation put me real close to Midsouth Shooter supply so I could not resist stopping in and buying some stuff....

    In one of my Dashers (my most accurate one) I used a Berger 105 VLD and 33.0grs of VV N540. I got 3070f.p.s. and UNreal accuracy! My vote is for N540!

    Good to hear as I bought both, heard and read great things about these powders and wanted to give them a try. The guy at the counter said it's all he shoots in his 22-250. They are temp stable and all have a copper remover in them.

    As I read the Viht web-site, ALL of the NEW Viht powders are: 1.) Temp stable; 2.) Clean burning (they always have been); 3.) Lot-to-Lot consistent; and 4.) contains the copper removing agent. To me this makes the Viht powders the best on the market.

    The first couple years with my 6Dasher's my pet loads were with N140 --105/107 bullets at around 3030-fps.
    Have also played with N150, but had much better results with N140, RL15, Varget, N540. It's a little to slow - IMO.
    Have also played with N540, but found it more sensitive then N140, but has more energy.
    Primarily due to cost, but also supply & demand, I got off the VihtaVouri powders back in the Obama days.
    Have used RL15 the most over the years. Varget, 8208, H4895 all worked well to.
    RL16 is my current pet powder for a couple barrels that have .160" throats.
    And the IMR Enduron powder 4166 makes speed in a 6Dasher size case like nothing else I've tried.

    On a note:
    I use a mild load (2850-fps) of Ramshot "Big Game" w/105 bullets for fire-forming & barrel break ins.
    False-shoulder method (+.020" crush) with real light neck tension, and the bullets .020-ITL.
    Waterline accuracy at 1000yds with that combo, and forms/blows consistent brass.

    dmoran---why the ramshot for your FF loads?, obvious success but what made you go there? why not just lower loads of your regular dasher/brx powders?

    Wanted a slower powder for fuller case fill to aid in case expansion, but still be a mild load, yet produce velocity.
    Also wanted it to meter well, so I can just throw the charges for fire-forming loads.
    Big Game fit those desires well, and proved out.

    Yeh I got some awesome results with IMR 4166 in mine but the powder has a super narrow window to load in.

    I use N540 for my 69 SMK. Great powder. I haven't used N140 yet....I have some for load development when I get time. Can't tell you much about being similar but N540 is some good stuff!

    I fire formed 6bra with 30.3 gr of 140 and it shot very well. I used some 105 Nosler CC. Got a jug of the new stuff and will try it at around 31.5 gr. with 105 hybrids soon.
    I like 140 super clean and consistent lot to lot. Seems to be a perfect powder for the BRA

    Tested out some OCW loads yesterday with the N140 and the results were looking really good. My BRX seemed to really tighten up the groups around 32.3 / 2972 to 32.6 / 2990 shooting 3 shot groups around 3/8 to 5/8 inch at 200 yards. There was a lower node at 31.7 / 2931 fps.
    Test loads with the N540 are loaded now and I hope to get back to the range this week sometime to try it. Will post targets when done...
