    I have a ? you guys. I built a mauser and I kept it in the original chambering of 8x57. I have been working up a load for it for about 2 months now and I am pretty sure I am going to stay with this. It is the third time testing this load and this was about the average for the other 2 times.


    I shot this at 300yds. The bullet is going 2520fps 10ft from the muzzle. The bullet has a BC of .520 above 2300fps, .505 from 2300-1700a and .461 from 1700 and down.

    Do you guys think it will still be stable at 1000yds? If not, what would be the max before it slows too much. I am not after a hunting load. Just something to shoot at water jugs and ballons at this range. 600 will be about the max for varmits.

    Well i looked up 30 cal 180/190smk out of an old manual i have and both are NOT subonic 1000 yards starting @ 2500 f.p.s.( but not by much). BCs and SDs should be close enough for this guess. So looks like your good to me @ 1k. Drop was near -320/330 in. @ 1k with a 400 yard zero.
    Good Luck
