30-06 N560 and 215 Berger Hyb

[bamban]

Rifle:
28 inch KBI 10T Serengeti chambered by me
SRS Ti Pro 3 ST
Trijicon Tenmile
700 worked over by me.

Loading and shooting on the range worked out a load with N560 and 215 Berger Hybrids. Pressure test at .5 grain increment topped out at 60.5. Initial results with limited data precision node with decent velocity appears to be 59.5. At this powder charge, bolt lift is a finger operation.

In preparation for the load work I prepped LC 67 Match brass. Pocket uniformed, flash holes de-burred, and necks turned to 0.013. Not all areas cleaned up to the thinnest areas, on the average 80% cleaned up. Pocket and neck work all done on the lathe. Here is a short video of neck turning. Mandrel turned insitu, 21st century turning shell holder in the tailstock is used to feed and and extract case. Turned mandrel is only good for this setting. Once taken down, next batch requires a new mandrel to be turned down again.



A few minutes ago deprimed the fired cases, all tight.

Thanks for sharing.

What kind of case fill did you have with that load? And roughly where was your bullet's base positioned in the case?

For scale here's how the 215 seats in the case before I pulled the bullet out from the round. Here's what I have. Powder was slowly dropped from a 6 inch drop tube and shaken tapped to compact.

Far better than me hand turning them.

Lightly sooted with sight black?

What is the COAL with the 215s touching the lands in the Serengeti Chamber?

My load is touching. 3.51

Thanks I was curious, looks ideal. Mine is a Rem 700 factory Bbl and touches at 3.650"
I still need to test Hybrid 100V with the 215s when I get a chance.

2838 is nice number from N560. What was your average velocity with the RL17 load again?

Wish I could find some of that LC 67 brass.

The same around 2830 something. I like the 560.

Come down to ATX I'll be glad to set up one of the lathes for you.
