No. They are a lead bullet with a jacket of copper/ nickel alloy.
It depends on a couple of factors, but it can range from none (on a subsonic round) to a couple of grains.

If the round won't fit into the handgun, then it's probably not chambered for long rifle rounds.
22 magnums actual caliber is .220. If you look at the tip of the bullet 22 mag has a sharp point. On a 22lr it is rounded and 22 mag is bigger around. Look around the rim and it will say 22 magnum or 22 lr.

- In DC hollow points are as legal as any other normal/non-restricted bullet. So possessing a hollow point *isn't* a crime only if you comply with every single requirement listed in DC Code § 7-2506.01. - The totally banned rounds are listed in § 7-2501.01(13A) (A) ("restricted pistol bullet"). One of the bullets on this list is a full-jacketed pistol bullet, over .22 caliber, if the jacket "has a weight of more than 25% of the total weight of the projectile". - And even if you figure out how to legally possess bullets in DC, if they're larger than .22 caliber rimfire, you can't possess a magazine that "can accept" 11 or more of them. See the "large capacity ammunition feeding device" crime in § 7-2506.01(b).
The .22 caliber bullet is ABOUT .22 inches wide. A .32 bullet is about .32 inches wide. The bullet will also be heavier due to size.
