Making new load for 243 using WIN760 powder and using FED LRP no 210. Found decent load with it but want to tighten up groups. OAL is now 2.625. How much would i need to change OAL to see a difference? Would i go .002 or .050 in OAL. Can i go below suggested OAL from powder company? They suggested 2.625 and in Hornady reloading manual they used 2.610 for an OAL with the same powder. I am using Nosler 70 gr BT. Shooting a Savage model 110. Any help would be appreciated.
