2 - 243's, 2- 25-06's, 3 - 30-06, 2 - 300 Win Mag. All shoot different loads, all shoot different bullets, all shoot different bullet weights. All are set up for different uses.
For example, one of the 243's is set up for my 4 year old grandson to use when we go to the range. He likes to make holes in the paper and ring the steel buffalo. Accuracy for him is minute-of-target and his big 'deal' is lack of recoil. The other 243 is set up for taking whitetails out to about 350.
