I worked up a load for my 300 RUM with the following components - Lone Peak Razor action, hardy CF sendero barrel (1-10 twist) and it shoots really well - but it's definitely a hot load: 210gr berger VLD 93.8gr of Retumbo Norma Brass Federal 215m primer 20 thousands off the lands Have a very visible plunger mark on the brass and a slight extractor mark - but no stiff bolt. The current posted data lists 92.0 gr as max from Berger for this load. **My question is - how many grains should I back off and start to work back up to find the lower node? I've seen some people recommend 1.5 grains, 1 grain etc - trying to short cut this so I don't burn too many rounds through it trying to find another good powder charge. Thanks for the help!
