I am new to reloading but familiar. I am needing to load some rounds for an antelope hunt that I should draw this year. I plan on shooting out to 500yds and want to use the 110gr accubonds in my 257 weatherby mark V with a 24" barrel. I have some imr 4350 and some 7828. I'm hoping to get my hands on some RL 25 and retumbo. If anyone has any suggestions on success they have had with different loads I am happy to listen. Thanks in advance!
