Home Forums Hunting & Shooting Long Range Hunting Ladder test, How, why?

Had 24#'s of h-4350 so I shot an Audette with the 139 Scenar. Nodes noted at 43.5 grains and 44.7 grains.

These are the middle of the node. Yes, 44.7 is way up there. That's what's great about the Audette. You find accuracy nodes and pressure in the same test. Hit pressure at 45.3 grains. The slowest burning lot of H-4350 ever made


Went with the 43.5 grain load and shot it till the barrel wore out. Gunsmith scoped it after I measured the lands being .250" from Max magazine length. He said, "remember where the throat used to start? It's about 1/2" of smoothbore past that to where the lands are now"


I went back to my Audette after increasing OAL til it wouldn't shoot anymore. Tried the upper velocity node and it shot well for a bit longer.





By definition, that's repeatability.

Save your target data and refer to it when things inevitably change.
