“Converting” 22LR plated rounds to subsonic? - Page 2

Mono core, unscrew the end cap, slide the tube off and clean the core. You can use the same brush you use for the host.

Even if you could pull, plate and re-seat the bullets, you would never get uniform crimps, and that is critical to any kind of decent accuracy in .22 LR.

(It is not widely known, but the early .22 LR rounds were not crimped at all because they couldn't get uniform crimps. That is why S&W advised not to use .22 LR in the original Ladysmith, not because it was too powerful, but because the bullets jumped and tied up the gun.)

Yup.
The original round with the 40 grain bullet of the .22 Extra Long in the Long case was known as the Stevens .22 Long, Rifle.
When crimped, it became the .22 S&W Long.

Long obsolete terms, of course.

There are a few experimenters working on black powder .22s. When the last shipment of primed .22 brass ran out, they had to go to pulling bullets, dumping the smokeless, ands starting over. Case expansion, powder charging, bullet casting and bullet seating are tedious operations. Not what you want to do to feed a Silent Plinking habit.

True .22 match ammo is subsonic from a rifle. Not plated, of course.
