Newbie needs advice

Both groups were shot with magnetospeed attached and both group speeds averaged within 15 fps of each other. Both days weather was similar temp around 35-40 degrees at time of shooting.

Vx5 has the zero lock as mentioned so it was locked out.

I felt like I was loading the bipod the same each time. I'm going to shoot the same loads today and try different amounts of loading and see if it changes POI. Reading online seems to be hit or miss on these leupold scopes holding zero so if it continues I'm going to lean towards the scope being the problem.
 
Try a group without magnetospeed. They do affect group size and impact on most rifles.
Mine always went significantly higher and groups were never great, but those are sporter barrels.
Just attaching the magnetospeed in a slightly different spot can change vertical combined with the seating depth change easy to get that 2".
