Thread: Test load temps

Ok. Im not saying that looking for a flat spot in the velocity wont be good place to start, I am saying you cant find it with a single shot per charge weight. You might fluke it but getting really lucky would be your best hope. The optical chrony you are using will hinder that process even more ,as light changes so will the readings.
Yes you are looking for a node in the velocity range that has the muzzel in the quietest/motionless faze as the bullet exits. How you find it is pretty big topic, books have been written on it.

First up though , what is your goal? what are you trying to achieve with this rifle and ammunition?
If its hunting deer to 300 yds then the group you described above is ok. Load up and go shoot some targets, a few groups at 100 to establish the genuine accuracy of you,the rifle and load and then out to 300 yds from different positions to see what your limitations are. You will benefit a hell of a lot more from shooting an ok load a lot than trying to tune a 1/2moa load.
