So I bought this model 12 from a forum member..single shot laminate 22-250. First thing I did was bed it with acraglass gel plugging tbe existing mag well. She already has a basix 2 trigger so that was good. Dropped on a demo vortex pst 4-16x50 mil scope and loaded up a ladder test with H380.

First test I didn't load hot enough. 325 yrds everything was pretty evenly spaced rising up.
loaded another a bit hotter and shot same yardage.
7/10 shots formed a 2" group...
hot dog! Loaded up some for group shooting and everything was horrible 3" or so. Mirage and wind were worst so I tried on a different day. Still crap. Tried shooting 100 yrds and groups are around an inch.

I dont get how its possible to shoot a ladder like that and have it go south. Tried cleaning the barrel and re torqueing everything. I ready to swap scopes. I have tried slightly different seating depths and charges.
