Thread: Powder for 30-06 and 270

    Powder for 30-06 and 270

    Hi guys, just bought a 270 and I also have a 30-06 I am going to buy some powder soon and want to use the same powder for both cals.
    Witch would be best Vit 140, Vit 150, or Vit 160. The 270 will be running 130 grain heads and the 30-06 150 grain.
    Many thanks in advance, Tusker.

    N140 is a bit snappy for a larger magnum cartridge like the 270/30-06
    I started on N165 for the 270 but moved to N160 and now use that for 130 and 150 gr bullets

    Don't imagine the 30-06 would be any different given the case dimension, it may benefit from a slightly slower burn for the larger 160-180gr bullets but I am sure an O6 loader will be able to confirm.

    N160 IMO (or RL22, IMR4350/4831!)

    Tusker H414, H4350 or Varget for both or Ramshot Magnum for the 270 can't seem to find a load for the 06
    AT THE AGE OF 50 I DECIDED I WAS GOING TO GROW OLD F***ING DISGRACEFULLY

    IMR4831 or H4831 will do both as will Reloader 19 and Vectan TU5000.

    N160 is my powder of choice in my 30-06 Ackley so it should be fine in the standard version. Spot on for 270 too.

    H4350, WW760, RL-19 will all work with hunting weight projectiles in both cals.

    The trouble comes with the bullet weights you are shooting, the .270 suits heavy charges of slow burning powders and the light for calibre 30 cal bullet could do with something a bit faster to get the velocity.

    Your choice seems to me to be optimise one calibre at the expense of some velocity loss in the other, use different bullet weights in the two cartridges to suit the powder picked or accept a small trade off on both and go for a compromise.

    In the case of the latter, H4350 could do very well in the role you describe as a compromise, a compressed load with a 150 grain bullet gives me 3000fps give or take from a 22" barrel and I believe the .270 was loaded with various versions of 4350 for years before the 4831 burn rate became available. I have had good success. I have no experience with RL19 or N150 but understand that they are of a similar burn rate, reloading data is available on the respective manufacturers' websites and show similar results.

    If you are prepared to explore different bullet weights the if you were to say dedicate the .30-06 to shooting 180 grain bullets, you could use H4831 or N160 successfully for both at optimum velocity. I had a great load of 60 grains of H4831 under a Hornady 180gr interlock for about 2650fps that I've hunted South Africa with. The classic .270 load is 62 grains of H4831, with top velocity, so this may be an approach worth considering. This shoots plenty flat, by the way.

    The last option is to compromise one for the other, in that case you need to decide which you will be using more and then just forget about it. A difference of even a couple of hundred feet per second from factory spec won't make that much difference on UK deer and would have less recoil.

    Personally, I would go for the second option.

    Over the years I have shot many hundreds of deer of various species and countless heads of vermin species with both the .30/06 and the .270 using Viht N160 powder.

    For the .270 Carl Gustaf I used 52 grains of N160 behind 130gr Speer SPBT bullets always with `standard`primers.
    The Hornady 140gr bullets printed one-inch higher on the target with the same loading with supreme accuracy.

    In my Sako TRGS .30/06 I used 56.5gr of Viht N160 with either the 150gr Speer SPBT or Nosler Ballistic Tip again with standard primers.
    The 165gr Nosler B.Tips also shot well with that powder charge but I found that the Ballistic Tips were more destructive on carcases and therefore I generally used the Speers when available.

    None of my loadings were maximum and I have never chased extreme velocities but always gone for the smallest grouping instead.
    For safety reasons always work up to the pet loads of others.

    HWH.
