Recenly had a RUM put together with 700 action and Proof 1:9.4 twist, 26”. I’m wanting to try Hammer bullets and wondering if someone may have experience with same barrel and tell what grain Hammer Hunter worked best for up to 800 yards or plus for accuracy and consistency? If willing to share load would be appreciated also. This is my second 300 RUM build. I’ve searched this site many times since start reloading 4 years ago and is wealth of info that has helped tremendously, so thank you!
