Thread: .270 Win, Reloder 17 and 140gr bullets

    .270 Win, Reloder 17 and 140gr bullets

    I would like to load some cartridges as title.

    I am new to reloading, and have so far worked up one gentle but useful load for an old 7.62 target rifle.

    Alliant's data for RL17 gives maximum loads for 100gr, 130gr and 150gr bullets as 59, 54 and 51.5gr respectively.

    Apart from asking them (which I've done, but no answer yet), is there any safe and reliable way to deduce the maximum load for 140gr from this data?

    Interpolation from the 130-150gr data gives 52.7gr, from 100-150gr data (omitting 130gr) gives 53.0gr.

    Extrapolation from 100-130 data gives 52.3gr

    What can one conclude from that lot?

    That the maximum load will not be lower than 52.3gr or higher than 53gr?

    That one should wait for Alliant to email back?

    Any thoughts?

    I would start at 51gr and work up towards 53gr nice and carefully watching for pressure signs.

    There is not a huge amount of 140gr Data around for the 270 so you will need to work it out for yourself. I would go carefully with Re17 as it is a bit on the fast side for a 270, and a small increase may spike your pressures. Work up 0.3gr at a time.

    Edited - Re-thought this. I might start even lower, maybe around 49-50gr's.

    I loaded 140's in a previous 270, 51.5gr of N160 was a sweet load and 53gr was max in that rifle. N160 is a slower powder than Re17.

    Just because you are paranoid, doesn't mean they aren't out to get you......

    RL22 is the N160 equivalent

    I tried R17 with 130gn bullets in my 270, it didnít work too well, end up back with H4831sc R17 might be a bit fast for 140s as said, but if you have a tub no harm in giving it a go.

    That's what I reckoned! It is at the quicker end, but Alliant give a load even for 150gr bullets. No harm in seeing how it performs, though...

    The fellow at Alliant suggests starting at 48gr, and a maximum of 'approx 52gr'.

    Thanks very much for the thoughts, chaps!

    Quick update, for those who are interested: The reloading novice, having got through about 1cwt of lead and powder has ended up with:

    Sako brass, Federal primer
    140gr Hornady BTSP
    51.3gr Elcho 17
    25thou off the lands
    Average 2860fps
    0.6-0.75" at 100yds

    which should do nicely.

    Dalua, that is a good result.

    A 140gr 270 cruising along at 2800 fps is a very pleasant load to shoot, and won't wreck carcasses. Approximates the 140gr load in the 7x57.

    Thanks. It is certainly pleasant to shoot, and as you say, should strike the balance between being humane to the deer and kind to the venison: while Hornady's slippery bullet should maintain a good flattish trajectory for the hill.
