my last batch of 30-06 fed SP's in 150g were easily shooting 1moa, had 3 rounds left and a new similar box but a new batch number. interestingly the new box had a protruding soft lead point, whereas the previous boxes I had were sitting inside the copper jacket, like a protected point.
in any case, shot a neat 2 shot group with two of the last three rounds to re-fould the bore after cleaning, then another of the new box to check zero with that batch (thinking it'd be about the same POI), 6" low...then adjusted up 6", right on, then next shot, 6" left, then one more, 4" high and left. I thought, bugger that, adjusted it back 'down' 6" and put the last of the previous batch through, bullseye.
ok back to the new batch, same problem, struggled to get 4-6 moa with the rest of the box,,,what a pile!!
same manufacturer, same bullet, same weight, but the bullet design was different...still, from sub 1" with one batch to +4-6" with the next...a bit weird no? and btw, as I was checking with a few of the 'old' ammo, the rifle was/is shooting as it should.
have you ever seen anything like this before? I feel a bit miffed as it was nearly £30 down the pan and now I'm of course no further in being able to take the rifle out on the hill until I find you ammo and re-zero if for that
