Wes-
I use electrical tape on all my guns, including my mz. Never an issue. Make sure you only use blue electrical tape though. :grin:
I'll be sure to only use "blue"!

I'm convinced the tape makes little change in POI at closer ranges.
But, seriously, do you believe there is
ANY change in POI, say at 150 yards? And does it matter whether you use thinner or thicker tape, criss-cross it (2 pieces), etc.?
I'm asking this in the context of realizing the charge should blow off the tape before the bullet gets there, but seems plausible that
SOMETIMES the bullet could still hit the tape a few yards out, causing an occasional shift in POI (think of shooting at a deer 150 yards away, but your bullet hits a cattail about 5 yards beyond the muzzle).
And knowing how such minute changes in any component effect rifle accuracy, it would seem a rifle sighted in without tape could not have the same POI when shot with tape. Has anyone extensively tested (say at 150 yards or farther) the POI for a rifle sighted in without tape vs. using tape later?
I know, I'm probably over-thinking this.
