Yes, it can be legal to make a silencer. For everything Form-1, from silencer designs that are easily made, to filing forms with the BATF, to 3D modeling. Remember, you must have an approved BATF Form-1 to make a silencer. All NFA laws apply.

I'm new to silencers....I was wondering if using a .45 caliber can on a .22 caliber rifle would quiet the .22?

Yes, it would. How effective is the question.

In addition, when wipes were legal there was
a noticeable gain in reduction.

A smaller diameter front cap could prove interesting.

In a long ago forgotten time OCONUS an armorer machined a .45
can from a solid 1.65" (?) ± diameter, 8"+ aluminum stock. For grins
he also made a front end cap with a .30"± diameter hole for .22. testing on
small handgun. The resulting volume, with noticeable reduction,
in field testing was, to say the least, 'over-kill' :)

For those interested, WIKI Historical forgotten factoid:

" ... Many [Vietnam] tunnel rats reportedly came to dislike the intense muzzle blast
of the relatively large .45 caliber round, as the .45's loud report could often
leave one temporarily deaf when fired in a confined space.[5]
Consequently, some preferred to clear tunnels armed with a .38 Special revolver equipped
with a sound suppressor[6] and other non-standard weapons.[7]

"A few of the OSS-ordered World War II era suppressed High Standard HD .22 automatics
made their way into Tunnel Rat hands. But these weapons were very few in number
and wanted by a number of other special units.
Personal weapons were used by the rats, ranging from .25 caliber automatics to sawn-off shotguns."[8]"

I should very much like to see a Vietnam era ".38 Special Revolver equipped with sound suppressor"...But if the internet say they were there, it must be true.

I would think a tunnel rat would have been tickled to have a suppressed 380 semi auto pistol. I know I would not want to be carrying a 1911 .45ACP or any type of .22 rimfire if I had that job. Come to think of it, I am pleased as can be to have never had that job.
