Thread: 6.5x55 load data for mid weight bullets with N160

  1. #1

    Question 6.5x55 load data for mid weight bullets with N160

    Can anyone supply any load data for 6.5 Swede, in a modern action, using bullets from 120 to 140gn and N160 powder only? I have just bought a tub of N160 as I think the powders tried so far, with the exception of H4350, haven't suited the Swede very well.
    Naturally I'll be working up a load, but it would be interesting to know what others have achieved, especially with chrono results.

    Thanks in advance.

    Hi Guesty

    140gr Hornady SST - 46.7 grains. Chrono 2,660fps
    120gr Nosler BT - 50.7 grains. Yet to chrono, but "book speed" is 2,970fps

    These are in my Sako 75 Syn St 20 3/4" barrel, and right at the top end of the reloading scale according to http://www.lapua.com/upload/download...uideed9eng.pdf - see pages 23 & 34

    Cheers

    120gr nosler BTs, 47.5grains of n160, OAL 76mm - sub one inch groups at 100yrds from tikka t3lite. Not Chronographed but guessing somewhere around 2750ish.

    Thanks guys, that's exactly the sort of thing I'm after.
    I've been testing relatively fast powders so far, and the highlights accuracy wise were H4350 and N150, but the speeds were lowish, and pushing harder gave pressure signs. N550 and Re17 got faster, but accuracy has not been so good. N560 and Re22 gave good speed with the heavier bullets, but again only so so accuracy. All of the above gave quite low load densities too.
    I'm hoping N160 might be the answer.
    My rifle is a Sako 85 with the 22 1/2" barrel.

    I use HPS-TR to reload for me, and as professionals at this I think they're likely to be on the money...

    Just got back from a very good day at Minsterley load testing for my recently acquired Tikka 695 in 6.5x55.

    I am a very happy bunny because a number of loads are spot on.

    Viht N160, 46.5 gn, 129 gn Hornady SST. Av 2690 f/sec. 5 shot group, .35" centre to centre.

    Also tested 3 loads using Tubal 5000 but you only want N160.

    The best part is the MPI for all loads tested is within 3/4"!

    Your 129gn SST load is producing the kind of accuracy I like, but will it go faster and retain accuracy? I was trying them with Re17 from between 2800 and just over 3000fps and was getting just under 1moa out to about 200 yards.
    Maybe they prefer going slower?

    In my case, the group began to widen above 46.5gn however the maximum load I had with me was 47.5 (I work in .5gn increments at this stage) and the first signs of pressure were apparent.

    I am happy with the 46.5gn load as it is accurate and deer legal (2070 lb/ft) and I know that most of my deer will be taken at under 200 yards. I also know that the terminal ballistics will be OK.

    It is often said that the Swede is happier slower, but I don't necessarily agree.

    Thanks, that is really useful info.
    I got the 120gn Amax and 123 Scenar to just shy of 3000fps with a 45.6gn of N550, and with good accuracy, but so far not had great success with the 129gn SST or 140gn Amax.
