Thread: 'Faster' powder for .270

  1. #1

    'Faster' powder for .270

    Having used some very popular powders for .270 in the past (H4831 etc) with good results, I am now looking to find something with a faster burn rate as part of some trouble shooting I am doing (scuse the pun).

    Has anyone experimented with faster powders and how fast have you gone (sensibly) ?

    I need something easy to get hold of.

    IMR 4064? N140? R15 or even Varget?

    Thanks. I'll have a look through these. Perhaps I should add, primarily its not faster velocity I want, rather a quicker seal of the case in the chamber.

    anneal your brass

    your brass doesnt know the difference between N160 and N150
    (BTW N140 will leave you with half empty cases and a barrel twanging crack, not for magnum cases IMO)

    RL22, N160, 4831 are all good burn rates for the .270

    why do you need a better seal?
    sooty shoulders?

    factory Norma ammo leaves a mark half way down the outside of the neck on my .270
    I get similar from the same Norma brass and moderate loads of N160 (it burns clean so no soot)

    The Norma brass is new (well, fired once) so shouldn't be an issue.

    The barrel is worn and has a fair amount of throat wear. The faster powder is next on the list and on the advice of a certain expert! Just wondering how fast to go. I might cross N140 off the list.

    I wouldnt rule out annealing mate as Norma brass is very thick on the neck and is known as hard brass so it may be more worked than you think.I would anneal sooner than change your powder it a damm site cheaper
