Speaking of... I just picked up a rimfire can from jail today.
You're right, there's endless hype about cans.
I've got a Yankee Hill Wraith and Silencerco Sparrow. The Sparrow is among the most popular, and the Yankee Hill Wraith is among the least popular.
The Wraith is a larger volume can with a 1.25in diameter and is 5.5in long. Is has superior sound reduction and near zero FRP... size (volume) matters. General Note for all cans: FRP is not an issue with .22 rifles, just pistols. The Wraith is a sealed can (most folks will tell you to never buy a can that isn't user serviceable) and relatively light at 5oz. I put 20k+ rounds through it then sent it back to Yankee Hill for cleaning. Free of charge. I put another 20k+ and sent it back to Yankee Hill. They replaced the baffle at a charge of $100. Could not be more pleased with the can in terms of performance and not fooling around with cleaning. It did gain a little weight before sending in for service but no perceivable reduction in performance. Nice quiet low tone. Being larger in diameter than most rimfire cans, it isn't well suited for pistols unless using a red dot or scope.
Silencerco Sparrow. The unique design of the Sparrow has made it very popular. It is user serviceable like many other rimfire cans, but it has a unique clamshell design that allows it to be taken apart much easier for cleaning after a significant number of rounds fired. It is a little on the heavy side at 6.5oz, but otherwise compact at only 5'' long. Unlike the Wraith, the clamshells and baffle is stainless steel and should last a very very long time. Nasty FRP... but relatively quiet after that.
Don't get too hung up on sound reduction specs because all rimfire cans are quiet enough that you really can't tell the difference unless you are comparing side by side listening for small differences. FRP don't mean anything for general recreational shooting because it's no where near loud enough for hearing protection. If it is an issue around the house or hunting, you can wet the can.
I would not purchase a centerfire can with the intention of using it on .22LR. You will hear that idea floated around by guys buying cans for their ARs. They are just too big and heavy for use on a rimfire pistol, and .22s are way too dirty anyway.
Do your homework and buy a rimfire can that best suits your criteria regardless of price (think Apple
). With the long waits and $200 price of a tax stamp, there's no sense in trying to save a few bucks and not get the can you really want. From the time I originally purchased the Sparrow to the time it was transferred to my dealer took over a month. Then it took another 10 months from the time I mailed in the paperwork until the tax stamp arrived at the dealer. Wait times are expected to be around 15 months now, and that doesn't count getting it transferred from where you buy it to your dealer. SilencerShop is a good place to shop online.
