I've had this .44 336 marlin for a good long while now
And I've been using the same load for at least 15 years and its always shoot good .
I've been out of gas checks for awhile and recently acquired a few of the old brass checks.
And my rifle hates them .. Groups opened up to about 10 inches @100 yards .
Other then the checks being brass instead of copper I changed nothing .
Same cases , same batch of unique , same bullet , same batch of lead .
Same lube ...
Anyone had this happen ?
I know the microgrooves can be picky , but I've never had gas checks make a huge difference before .
