Hey guys, my buddy is helping me develop a load for my 300 RUM. At the range yesterday he had 6 different loads of 210 Bergers. They were loaded with a COAL of 3.680. Quite simply, the bolt would not close with them seated so far out. Factory ammo and some other handloads that were seated deeper had no problem. My question to you is what is the longest COAL you are getting away with. FWIW my gun is a Rem Sendero SFII in 300 RUM and I'm using 210 Bergers and 180/200 Accubonds with Nosler brass. Thanks in advance.
