Re: Why does my long range rifle have to weight 12lbs +?
While I agree with Bart for the most part, I have seen and it stands to reason as well that a heavier barrel will be less affected by the very slight differences in charge weight and primer flash in ammunition that one might see from one round to the next. The heavier barrels/rifles will absorb more of the changes in vibration/harmonics caused by a slightly warmer or cooler load, making it easier to find an accurate load for the rifle. A lighter weight barrel will naturally flex more when it is fired and will be harder to make it do exactly the same thing every time with even the very slight differences seen from one round to the next in even the most maticulously loaded ammo. However once you find a good load for a light weight barrel that it consistently shoots well, provided you are willing to put in the time necessary to do so (most here certainly would), the weight of your rifle/barrel will make little difference and it comes down to the man pulling the trigger.
