Merry Christmas, OLB.

A silencer, supressor, muzzle brake or flash hider will only cause problems if misaligned to the barrel. 

If properly fitted the bullet will not make contact with the unit, but should pass through clean.

It will only affect a bullet' s path if it improperly fitted and the bullet makes contact - becoming essentially a ricochet..

Alignment is important. That's why I have a couple different sizes of alignment rods to check that kind of stuff. Supposed to be straight to within 1/1000" over 12". Baffle design is important too. Poor baffle design can cause enough turbulence to change a bullet's flight path and cause a strike. I compensate with an oversize bore. The one pictured above has a .280 bore. Gives me a lot more clearance than the .25" bore a lot of people use. Of course all else being equal a .25" bore would be quieter than a .28" bore...
