[QUOTE="Lonewolf74, post: 1316123, member: 96274"] Ok I want to use an example to make sure I'm understanding correctly. Using my 243 and RL25 for the example (numbers are close not exact). I load up 6 rounds one at each charge of 45, 45.5, 46, 46.5, 47, 47.5. I get a cluster of 45.5-46.5 hitting about the same spot and about a 45fps difference between the 3. At 47.5 I start to see light pressure signs with a flattened primer no other marks. So would you choose 46 grains cus it should be about the middle of a node? Or would you choose 47 grains cus it's at max working pressure? What would be your next step once you have chosen the charge from this initial test? [/QUOTE]
