Sorry n-565* was used. Not 566. Fat fingers lolDid a ladder test with my browsing hells canyon 28 nosler. New gunwerks brass, n566, 162g eldm, and federal 215m primers. Here are the results for velocities. Where would you start after seeing this?View attachment 171817
Forgot to mention I never had any pressure signs and I was .2 grains away from max load in the book with the last shot. I was thinking of loading up 5 or 6 more going up the ladder and finding where I hit pressure and see if I can find another flat spot. I like that 80.2-80.6 velocity. I'm hoping I can get some good accuracy there.1. 79.2 to 80.0
2. 80.2 to 80.6
Seems like #1 offers a very wide flat in velocity. I would start here looking for a node.
#2 also has a flat, not as wide, but assuming you are close to max charge. It's worth doing if #1 doesn't settle down in ocw testing.
Speeds are very close in either so I would prefer to be off the max load in #2.
What range and what did the target look like?
Yeah 200 is the farthest I can get for now.I would try it farther out- as far as you plan on hunting/shooting that combo if you can and look for least vertical
At 200 it's hard to tell what will be best.
79.8 or 80.4 appear to be the middle of two fairly flat node areas. I will suggest running the test a couple more times. One data set can be deceiving. If I had to pick one based off of this I'd say 79.9.Did a ladder test with my browsing hells canyon 28 nosler. New gunwerks brass, n566, 162g eldm, and federal 215m primers.
