300RUM build with 210VLD COAL?
Hello guys, could use a little input here. I have a Rem 700 in 300wby with a 27" #5 lilja on it. I use 210VLD's exclusively but want a little more speed. I have decided to rechamber to 300RUM. My question is in regards to COAL. I have an outstanding gunsmith who is very familiar with the 300RUM but has never set one up for 210VLDs. We talked about setting the rifle up initially for 3.600 as the standard COAL. This however puts the Berger very deep into the case possibly causing a loss of capacity. I am almost certain that the bullet will need to touch the rifling or be .010 off, that is what I was doing before to get accuracy. I am not concerned about fitting the cartridge down in the magazine, if it needs to be a single shot so be it. I will probably be able to put one down like before anyway. What are your recommendations and experiences with this set up, do we need to go longer COAL like 3.700 or so? Thanks, Jesse
