Thread: Quickload data for .270 load

  1. #1

    Quickload data for .270 load

    Hi all

    Would it be possible for someone to run some details of a load for me through your Quickload programme (or similar) and let me know the resulting velocity.

    Hornady .277 130gr SP Interlock #2730
    52.5 gr Hodgdon H4350
    Federal 210 primer
    Norma brass
    C.O.L 3.180"
    Sako 85 20" barrel

    Thank you in advance.

    About 2900 fps from a 24" barrel.

    (They have a better quick load than Quick Load)

    Thanks Muir forgot to add 20" barrel so that will drop the velocity a bit I think.

    prov to get a acurate ish speed you need to measure the h20/water capacity of the case

    Hi 223

    what is the volume measured in (mm ? mm3 ?) and how would it be best to do this ?

    get a case and full length size it

    then put a primer into the case (so the water does not run out the hole)

    gently pour water into case till full completely level with neck of case

    then pour water into reloading scale pan and measure the water capacity in grains, and that will give you the internal capacity in grains of that make of case

    do that then pm me and i will enter it all for you

    I get 2713fps out of a 20 inch tikka t3 sporter, 55 grains of H4350, using barnes 130 grain tsx, 30 thou off the lands, that's max load in barnes manual but there are no pressure signs, and very accurate

    So deduct about 35 fpr per inch. That would put you in the high 2700's. The very best thing is to go in on with a few guys -even members of this site? and group buy a CHRONY chronograph. get together or mail it to one another. Beats all the trouble of coming to an educated guess... which is what Quick Load and supplied loading data is. It almost never matches your gun exactly.~Muir

    I've never had to do this, but would a significant bit of water not remain wetting the inside of the case?

    Might it be better, having prepped the case as you suggest, to weigh it and note the weight, fill it with water and then weigh it full of water? The true water capacity would then be the difference between the two weights.
