I was testing a bolt 6.5 Creedmoor and a Howa bolt 6.5 Grendel.
Thought I'd post both results.
Sea level. 92deg F
6.5 Creedmoor Ruger Precision rifle
LAPUA NATURALIS lead free 140 gr
H 4350 powder
federal 210 m primers
Measured velocity using a Magnetospeed.
40.5 grs 2636 fps
41.0 grs 2665 fps
41.5 grs 2667 fps
42.0 grs 2712 fps Retrieved
42.5 grs 2732 fps Retrieved
43.0 grs 2754 fps Retrieved
The 3 bullets in the photos are the last 3 fired. Expansion was good. Bullets stayed together well.
6.5 Grendel Howa heavy barrel
LAPUA Naturalis 140 gr
CCI 450 primers
LAPUA brass
CFE powder
I was a little hesitant to go too high with no published data and CFE being what it is.
There were no pressure signs at all.
I did not retrieve any of these bullets.
26.5 gr 2086. fps
27.0 gr 2108. fps
27.5 gr 2150. fps
