Loaded my buddy's Revolution and my Omega the night before hunting.Put tape over the barrel. The guns were in a walkout basement where we keep the hunitng supplies at about 55 degrees. after the morning hunt we shot them and both shot about 2 inchec low at 100 yrds. Is this common or was this a fluke? I haven't had a chance to retest.
That two inches is very good. Many here will tell you it sometimes gets worse than that. These MLs are funny creatures.
If you sight them in on a fouled barrel, they shoot best on a fouled barrel.
If you sight them in during high humidity, shot groups will change when there's low humidity.
If you sight them in during 70 degree temperatures, shot groups will change at 25 degrees while hunting.
If you sight them in & shoot them every three minutes, they will shoot differently than shooting only oncelate in the hunting day - after that powder was exposed to the elements for an entire day inside your bore.
Several hours outdoors with the breech and muzzlee sealed still won't stop the accumulation of moisture. That moisture can penetrate any powder weaken it enough to drop the bullet two inches.Any moisture can form while inside two sealed ends of a metal pipe (your barrel).
Sometimes sealing both ends creates more moisture than not sealing the muzzle-side. I never seal my muzzle unless I'm walking thru thickets. Then when I reach my destination, I take the tape or wrap off. That's to stop pieces of branches from entering my bore.
