here is the link to the thread about my rifle and I continue to post my findings in it.
my new 7mmx300win
why bother with Retumbo? because nobody can say for sure yet if RL33 is temp sensitive and i'm not done with testing it either, all I have done is velocity testing.
Subscribe to my thread and I will continue to post as I try different powders and bullets in it.
FWIW I got 3150fps with 75gr of H1000 also but ran into pressure before I got to 3250fps so the RL33 for sure gained me some velocity but like I said i'm not done testing. heck I havnt even tried different seating depths yet just powder charges checking for pressure/velocity
