Ladder Test for finding powder charge

[Frequently Banned Troll]

Ever done that? Was it a good use of time?

I’m trying it for the first time this weekend. Two rifles, same caliber (6.5prx) 2 separate loads - every component is different. I’m hoping I can hone in on a good recipe in 2 times out shooting. Will see.

I’m going to shoot at 300m because parallax is that for the optics but will plot both impact and velocity.

I've done it for different bullets in my .308. Gave me a good understanding of pressure and velocity in that particular gun using different powders, primers and seating depth. Gave me a good idea what the gun likes/dislikes
