Firing non Subsonic.22lr through my moderator

Kran

Just wondering will firing non subsonic rounds like CCI velocitor and mini mags damage my moderator? Also if anyone has experimented with this how far off would the difference in zero be?

Nope, won't do any damage to the mod - difference in PoI will vary from rifle to rifle. It all comes down to the resonant period of the rig with and without the mod vs the residency period of the bullet in the barrel.

Won't do it any harm, and the change to the zero will be round specific.

Bit odd though as a working rig, as the mod won't do anything to muffle the crack of the round going supersonic

I get consistent zero with either Ely Subs or Winchester Subs (black box 40gr, for the life of me forgot the name) at approximately 55 yards. If I switch to Federal bulk high velocity (woefully inconsistent and cheep) the only consistent thing is they are high by 7 inches at the same zero (55 yards) and are on, if you can call that grouping 'on' at 100 yards.

My only reason for thinking about it is that I found two old boxes of cci velocitor and 100 mini mags. I have it zeroed with cci subsonic but I thought I might carry my spare magazine with the velocitor rounds just in case I spotted a fox when out. Don't think I'll bother now as I hate messing around with my gun when it's zeroed. Good to know it won't do any harm though.

Wow 7 inches is a lot for 55 yards, I'd have guessed an inch or two.

Why not just fire a group of 5 Velocitor at a target.

If they are consistently about 3-4" high & on target then you'll know to aim 3-4" low ...if using them.

Practice then using them at a target, aiming low at the required amount, and you should be bang on after a few shots.
