If his "standard" load is on the lower end, and he reduced it by 10%------couldn't that become an issue.....?
You do really need to drop back some and work up at least for accuracy sake.

According to Midway and some other resellers, "[...] CCI Number 41 Mil-spec primers are made to the same specifications of the U.S. Military and reduce the chances of a slam-fire. While designed for Military-style semi-auto rifles, they use the same data as CCI magnum primers." I checked the CCI site and there is no such matching declaration to, "...use the same data as CCI magnum primers." All CCI says is they're built to Mil-Spec. Winchester says the same thing but their #41 primers say on the box, "WMSRL" whatever that means. I guess the next question is, are Mil-Spec small rifle primers the same as commercial magnums?
There's all kinds of variables and a specific answer covering every gun and every load would take a few pages. Bottom line (and good reloading practice!) anytime any component is changed, do another load work up. Some drop 10, some go back to book starting data...
