Similar experience, anyone ?
      07/08/05 07:47 PM

I just had my FN-Browning o/u 9,3x74R re-regulated for the softer 285 Norma Alaska (it shot perfectly with my former Blaser 286 CDP's but I found them too hard and not expanding enough). I went to the range and shot some of the left over ammo (fresh Norma factory loads) that was used for regulating. 2x2 shots grouped within 1" at 50 m, Ok thus. Then I tried some 15 year old ammo (same factory load, same Norma reference, of which I bought several boxes at a bargain price) and was appalled to find that with these, the bbls. were crossing 5" apart. Evidently, both factory loads were not the same. I'll dismantle them and try reducing the original powder charge by a few grains so as to lower velocity a bit and counteract the crossing, in order to bring the bbls. together. Hopefully, I'll be able to use up my old ammo stock that way.

3 shots do not make a group, they show a point of aim or impact.
5 shots are a group.
