Hi, can anyone help. I bought a 308 secondhand,chap I bought it from loaded me some rounds 45.8 gr vit n140, 150 gr sst bullet. Just didn't get on with them so reloaded, starting from 39.9 up to 47.7. A load of 43.1 suddenly went to sub .5 nch group.
the bullet length was 2.765 (the same as the ones loaded by the previous owner) have measured chamber and it is 2.869 long.
the rounds are for hunting so here is the question. Should I stick with 43.1 at 2.765 or should I reload 43.1 at various lengths up to .015 off the full length. Will the accuracy increase by getting closer to the lands?
thanks for taking time to answer.
