I would bet your trouble is that simple.
When I set one up I typically measure 3-5 times and never have more than a .002 variation but I have to un-stick the bullet every time.
You do not need to pry or hammer on it but it needs to be "firmly planted" in order to get consistent results.

OK maybe that's it. I assumed if I did anything more than just barely laying it in there that I would be cramming it in the lands and through in it off. I'll try to set them in a little firmer tonight

how nany rounds do you have through this riffle? also every brand of bullet will not be the same measurement to the lands but im sure you knew that.

Give this a try....... Scuff your bullet with steel wool or a fiber pad. Just enough to take the shine off. When the bullet touches the lands it will have small bright spots made by the bullet contacting the lands. This will tell you if you're using enough pressure on the rod. If you find more pressure is required you can prevent the bullet from sticking in the lands by applying a little case lube at the part of the bullet that will be touching the lands. ...... Quite often a bullet that doesn't stick in the lands will result in the bullet being pulled out of the case slightly which yields erratic measurements........ Oh, and it helps to hold your mouth just right :)....... BTW the marks you find on the bullet should be almost square on a newer bbl. The marks will be more oval in shape if the throat is beginning to wear.

Didn't think about scuffing a bullet. Thanks for the tip! That's a good idea.

The gun has a few hundred rounds through it. I honestly haven't done a good job keeping track but at least 300 I'm sure and ya I was using the same bullets every time I tried to check. Same lot and everything.
