the last year has seen several new SPECIAL loads released for 22 rimfires that are designed to actually expand in the small barrels. however the issue is
these loads are not easy to find at this time. these loads are not cheap to find either.
as a result the person who spends 450.00 on a 22 lr or 22 mag revolver is going to use what ever they can find at the gunstore that costs less then what it would take to get the fancy new loads online. (standard shipping handling, sales tax, hazmat fees, etc) and simply use the WRONG ammunition.
yeah, bullet selection isnt going to be good when all you can get locally is varmint ammo designed for a 20 inch barrel, or target fmj.
