Immaterial. The .22 won't be able to reach the scoped sniper. Even if it could, it won't have any effective results after 150yds.
A 40 grain bullet at 1,082 ft/s versus a 121 gr. round at 2,356 ft/s...effective to about 350 yds...is a loser.
Where Im at the trees are so thick the longest range is about 100 yds unless you’re standing on the interstate.
Like I said, in an URBAN environment, the range of the Mosin won’t matter. You will rarely see that type of range or be able to acquire a target in an URBAN environment.
Meanwhile, a big honking, LOUD Mosin will be very noticeable.
The Israeli’s used integrally suppressed 10/22s to drop Palis. It’s become quite popular. Combined with urban ranges and semi-auto action with a 10 or 25 round magazine, and you can own your castle with anonymity.
But if we’re talking 350yds, why limit yourself to the heavy, unwieldy Mosin when an intermediate cartridge rifle like an AR or a Rem/Win bolt would do the trick?
