Re: Retumbo or RL-25 for 300 Ultra in factory Rem 700
I would try them both. They both work good in 300 RUMs.
I personaly have had better luck in the accuracy department with the RE25. That said, a buddy of mine is doing pretty good with Retumbo in his factory 26" stick. Getting 3120 FPS with the 200 AB's and sub .75 MOA accuracy.
I know some guys are using the Tubbs final finish on their factory barrels and run H1000 under the 200 AB's at 3200+ FPS. The key here is final finish.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
