thanks for any comments.
Here is all of the info I have:
New Nosler 7mm SAUM brass; 180 Berger VLD; 210M Primer in all loads. .015" into the lands (3.040" OAL). Temperature was 45 degrees.
64.5 gr 2869 fps
65.5 gr 2925 fps .40" @ 100 yards
66.0 gr 2950 fps .36" @ 100 yards
64.5 gr 2917 fps
61.0 gr 2781 fps
62.0 gr 2811 fps .566" @ 100 yards
63.0 gr 2890 fps .485" @ 100 yards
I didn't experience sticky bolt lift on any load.
My plan is to play at 300 yards with 65.5 to 66.0 gr Retumbo and seating depth.
The rifle specs are as follows:
Remington 700 LA
Krieger 26" #5 contour; 1:9” twist; 5R rifled barrel
McMillan Remington Classic stock
Burris Zee rings and mounts
Leupold 6.5-20x50mm LRT with standard plex crosshair and M1 turrets
Beartooth Products cheek piece
Gunsmithing by Louisiana Precision Rifles
I hope that helps. Please post anything you come up with.
