Re: 338 300gr. Nosler CC ?
There is much truth to the old saying, "If it ain't broke, why fix it?" Be cautious with changing a load producing proven results and confidence. The time it takes to develop a new load may be the same time for bullets to hit the market. Fingers crossed. As stated, there are OTMs available now with only a jacket thickness difference to the ones you currently use. I used the OTMs last year assisting hunters on three elk and three deer with an average distance over 800 yards. No problem putting the animals down. My .02 says stay with the Berger 300, either one.
