I worked up loads for a 260 I no longer have. I have 100rds of the prefered load for that rifle. I got a new 260 and am comteplating shooting these in it. I will have to seat the bullets a little deaper to fit in the mag. Its that or pull them all and start over. Would it hurt to try them in the new rifle? The worry is they at published max which is what the other rifle shot best.
