My 15 year old son has a left handed Browning X Bolt hunter chambered 7mm-08 with a Leupold VX3i 2.5-8x36.
For the life of me I cannot get it to group all of a sudden.
I have tried the following:
- Took scope and Talley rings off and installed and torqued everything back down. Bases at 28 and rings at 17.
- Tried Hornady Superformance 139 gr. Interlock, Remington Core Lok 140 gr. and Nosler 120 gr.
- Shot off Caldwell The Rock with rear bag (what I normally use)
- Shot with a lead sled
- Paid close attention to amount of pressure into shoulder/sled. Made sure that as I applied more pressure the crosshair wasn't moving, etc.
- Cleaned Gun really good with bore guide and Dewey rod.
It is like I can't get it to zero. Shoot 2 shots 1.5" high and 1" right (.5" group), but the third shot is 4" high and 1" right. Okay, so maybe I didn't have the same back pressure on one, so I give it 4 clicks left. Next round shoots 1" left and 1.5" high, so I send another and it shoots into a .5" group, third shot goes 2" left and 4" high.
I'm at a loss?? I mean I just shot a .3" group with my 308 Win. My son cannot shoot a group either.
Please help!
