Thread: Viht N160 for 243 95-100 gr

  1. #1

    Viht N160 for 243 95-100 gr

    I'm looking at powders for my new 243 (Brno Mauser 98, 22" 1:10). Viht N160 comes highly recommended in the Hornady book, but is only listed for 87gr and less. It's funny cos they list 4350 and 4831 for 95-100 and n160 sits between them in burning rate.

    So has anyone had any success with N160 with heavier bullets, and if so what were your good loads. Or N160 for 243 in general.

    My other thoughts were IMR4831 - trying to find something that will handle 95-100, 87 and 80gr in that order. I know "what powder for my 243" is a can of worms, but any small pointers would be appreciated. I think I've ruled out 4350 (things I've read) and 4064 (too fast for heavies).

    Hi Harry I use 41.5 gr of imr 4350 with 100 gr hornady spbt really accurate load. and 40.5 gr varget with hornady 75 gr VMax again really accurate load and devastating on foxes.

    thanks, does it give good velocity (3000+) with heavy pills while giving acceptable accuracy with lighter ones?

    What about cost, i hear rl powders are a bit more than others?

    Sounds good. Any idea what speed those 100gr pills are doing? And what length barrel and twist don you have?
    Is there no way i can use one powder successfully for light 100 and 80gr pills? Even if i'm not worried about 80 speed?

    You will be struggling to push a 100g .243 bullet to 3000+ Re 19 with max load will give you just over 2700 which is perfectly
    acceptable, regardless of which powder you use don't expect much more than 2800 with a 100g bullet and thats at max loads
    which are often not the most accurate.

    Ok. I just wanted to use it to it's full potential, and seeing as the hornady book lists quite a few (imr 4831 one of them) powders that push 100s to 3000 i was wondering if n160, or any of the accurate light pill powders could safely do that as well.
    I guess they were using a 24" barrel but would 2" really drop me 300 ft/s?
    Also, i know i may find 100gr pills not the most accurate, but i may do some scottish stalking on reds, so don't i legally need 100s for that?

    I use Vit160 in my 1 in 10 sako.
    44gr for 85gr Sierra Varminter and Vmax.
    I used 41.7 for 90 gr speer hot cor which maybe a little hot as I did not chrono the speed as I did not have one at the time.
    I used factory 100gr and they were ok in the gun

    This is a scan of the 2004 Vit manual for 243 which I used, the 2008 manual has higher powder charges and hotter loads for some reason, as I chonoed my loads I know that these loads are more appropriate than the 2008 loads.

    You might have to click on the image to enlarge it to read it but it offers loads from 70gr to 100gr for 1in10

    Yes you should be able to work up loads with one powder to shoot both rounds, don't shoot 80g so can give no advice on it
    other than looking at powder charts you should be able to push your 80g to over 3000 depending on powder choice again that would be max loads, as said already max loads are often not the most accurate.

    Don't know how much reloading experience you have but be careful of max loads stated on charts always start on min. load and work up.

    For example in my case 100g Hornady boat tail 37g H380 magnum primer [ALWAYS USE MAGNUM PRIMERS WITH THIS POWDER] this is max load, dont have a crono but on paper should give a speed of 2717 Re 19 same bullet but 39gpowder and normal primer should in theory give approx. the same speed. In my rifle its inaccurate backed off to 37 g shoots to same POA as
    H380

    Nosler 95g ballistic tips loaded with 36g H380 also shoots to same POA as the above.

    Worked this load up to 38g but at that would not shoot to same POA as the 100g
    To date have not worked up a load in Re 19 for this bullet.
