Thread: Vihta Vuori High Energy propellants

  1. #1

    Vihta Vuori High Energy propellants

    All righty then- I've been perusing the Viht reloading manual, and it seems that the 5 prefix powders can offer a bit more velocity- no big deal for most stalking calibers, but I could use a bit more Vooma from my Remington's 26" barrel for F-TR.

    So, what are the downsides to using a 5 series powder as opposed to the standard propellant? More bore fouling? Bigger SD? Or are there no obvious disadvantages to using N-540 instead of N-140?

    Main downside is they not very temperature tolerent so if developed this time of year you can get a presure spike in the hotter months, if you still want to persue them I have an unopened 540 and an opened but not used 560 here at 50 each.

    +1 despite the ******** on the Vhit site stating that there is no increased barrel wear, they have a ferocious appetite for throats. I have a friend who used N530 in his 16" barrel RPA 308, it got to 3000fps with a 125 ballistic tip, but his throat was buggered in less than 1200 rounds, theres no such thing as a free lunch!

    Aaah, see I know there was a catch somewhere. I'll stick to RL-15 for now.

    Thanks for the info.

    RL-15 is also a double based powder so it also burns hot. A barrel is a disposable item IMHO get a good load worked up then enjoy it while it lasts.

    Of course some would know better than the patently incorrect manufacturers..

    If that remark was aimed at me then i suggest you get a borescope and see for yourself. I like Vhit Powder and i have no problem using 5 Series, in certain applications it works very well. But there is a trade off in barrel life. Perhaps for a stalker this would be less noticeable due to reduced rates of fire compared to F Class use, but it is a fact.

    And of course some learn from experience rather than listening to sales pitches.

    Didnt know that . What about varget, h4895 and benchmark, are they double or single based ?
