I have one rifle that tends to walk as it heats up .... I say tend to but really it’s basically guaranteed.
It’s a full length forend and figured wood so the grain is not straight and the forend always contacts the barrel. I’ve tried to correct it a few times to no avail.
On the upside. The walking is pretty predictable if you take quick follow up shots, and if you let the barrel cool it doesn’t walk.
