    n-150 in 25-06

    need help anyone using n-150 in 25-06 with sierra 90 grain hollow point boat tails,getting conflicting data viht giving max at 44.9 grains and a reloading web site giving 51.5 as max, anyone have any hands on experience,any help much appreciated thanks

    Go with the viht data. It's 38.7-44.9 for 87gr bullet in the Lee book. I don't think that the powder is best suited for the cartridge.

    I'd agree..Viht. N150 - not the best propellant for .25-06... H4831 or close similar with a 90gn bullet. ATB

    You can of course use it. The Viht. data is there for the 90gn bullet...it's just that it isn't the best choice of propellant, lagging behind somewhat in terms of MV it'll produce. But you can use it.
    Thing is though, a .25-06 thrives on MV so the propellants producing top end MV will always work best. But the 90gn bullet most certainly should work with the 1-10 twist most .25-06 rifles have.

    deeangeo your rignt about the mv im going to try some n160 its close to reloader 19 in the burn rate, trying to get away from the american powders as its hard to find down this end of the country due to the americans not shipping much over.viht powders are quite easy to get hold of so want to switch to viht n160 ill keep the n-150 for my 308 thanks again

    OK but you can also take a look at Ramshot 'Accurate 4350' propellant. Made in Belgium. Cheaper too! I know Krank imports the stuff, don't know who else, but I think it's viable powder although don't have personal experience if it. If their Accurate 4350 is a comparison to IMR4350 or H4350 it should be good..especially at £32/34 a lb. As a max load they list 3472 fps with 24" barrel & 54gns Accurate 4350.

    Just put it through QL based on coal of 3.122 and 20 inch barrel. You would expect a max load if 54.2gr and an MV of 3254fps. This is with 100% efficiency so not a bad choice. Not sure if that is the MV you are after. If you let me know the specifics of your rifle, barrel length, twist rate and what coal you intend I can be more accurate.

    Quickload is a computor modelled prediction program not actually derived velocities from firing said bullets, i would not reccommend 54.2 of Vit 150 it is way over most published data, for instance the Sierra manual says 49.2 max for a 90grn bullet.
    Stick to the books, that way you know that the load published is going to be safe in your rifle

    QL never let me down. Most books always er on the side of caution. Any sensible loader would start at 10% below max and work up looking after every round for signs of pressure.
