Thread: 7x64 Brenneke Powders?

  1. #1

    7x64 Brenneke Powders?

    Anybody give me some pointers on what powders they use for the 7x64 Brenneke. I've been looking at R17, R22, H414, H4350, IMR4350 because that's what I keep!?
    Thanks TDM

    What bullets and what game, at typical and max ranges?

    For UK Fallow and Red - Sierra 160gr HPBT GK - Ranges generally 50 to 200 yards
    S.Africa / Plains game - Nosler 160gr Accubond - Ranges can be 200 to 400 yards

    I might have a play with 140gr bullets as a friend of mine, a PH in Bloemfontein, uses Hornady 140gr InterBond for all Plains game in his 7x64 and swears by them. He uses some odd powders I've never heard of! In this weight I'd probably use Accubonds, see what's available.

    Thanks

    The Sierra 160-gr HPBT is probably as tough as the Accubond, at half the cost. High BC.
    The Sierra 160-gr SPBT is softer. They both shoot to the same place out of my 7x64s and .280 Remington.

    57.0 grains of VV N-160 is super accurate. Max load, so work up.

    53.5 grains of IMR-4831 gives 2,850 fps
    50.0 grains of IMR-4350 is near max, 2,800 fps.
    51.0 grains of RL-19 (2,700 fps) 52.0 grains max ( 2800 fps)
    52.0 grains of RL-22 (2,800 fps)

    Try some 150-gr Sierras, Accubonds or Hornady Interlock 154-gr with 51.0 gr IMR-4350 for 2,875 fps.

    I want to try a 140-gr Barnes in mine, with 52.0 to 57.0 grains of RL-19 (2,900 to 3,100 fps).

    Have a look at Vihtavouri, they list a few

    I have not tried H-414 (W-760) in a .280 Rem or 7x64, but a friend uses about 52.0 gr for the 120-gr Ballistic Tip and the 140-gr Sierra in his .280, a Custom Shop Model 700 with a 22-inch barrel and Kevlar composite stock - very accurate. He hunts in big woods, and big grain fields. This thread reminds me to ask him about his exact recipe.

    Apart from H414 maybe most of these will work.

    Federal used IMR 4831 in these .......

    If I'm going to be accused of it then it's just as well I did it.

    Thanks all. The IMR 4831 looks good on paper and Quickload, I might just need to find some.

    Southern, interesting what you say about the Sierra HPBT v the Accubond as being just as tough, that's what I was hoping. I use the Sierra in 140gr SPBT and HPBT in my 7mm-08 and find them very good the HPBT slightly more accurate and solid.

    This is all a bit cart before the horse! I've got all the re-loading components and the rifle but in the wrong calibre! Hopefully get the barrel switched over in the next couple of weeks. Barrel 1:9 twist or there about, still to be decided?

    Is your rifle a Sauer 202 switch barrel? Try the N-160 and 160-gr Sierras. 4831 is a great powder, too. I got that about the Sierra 160s straight from the engineer at Sierra, as I was curious and called the tech support number.

    My .280 is 1:10, Mauser is about 1:8.7, Steyr somewhere 1:9+. The .280 and Steyr 7x64 have, so far, shot everything from 120 to 175 really well. But there are so many good 160-gr bullets, that I may just settle on a mix of that weight for all of these 3 rifles, plus the one I just built ( still trimming it out ).

    I use about 43 grains of varget under a 140grn Nosler BT
