To be honest, I think that the Thunderstruck is an interesting concept, and I'd like to see it scaled up, given longer barrels, and chambered in larger caliber bullets. I like .22WMR, but this particular firearm doesn't appeal to me in .22WMR. I think the folks calling for it in .327 Magnum may be onto something, as it could easily hold 6 shots in .32 H&R Magnum while maintaining the same dimensions, and pack a lot more of a punch.
I've actually been curious to hear how it performs from somebody who actually owns one, so it's nice to hear a bit about from you. Considering that most armed confrontations take place within 7 yards, accuracy out to 15 yards is more than adequate for the purpose it was designed for. I'm not surprised that it went 500 rounds without a misfire, as .22WMR is far more reliable than anybody gives it credit for. Folks get all hung up on it being Rimfire, assuming that makes it no more reliable than .22LR, forgetting that .22WMR uses an inside-the-case lubricated bullet. With modern priming compounds, rimfire bullets are far more reliable than they ever were before, but the.22LR is still using an outside-the-case lubricated heeled bullet, which is extremely susceptible to contamination as well as moisture, ergo the .22LR is inherently more likely to have dud rounds compared to .22WMR.
I can't fault you for getting worked up over the perceived criticism of a firearm that you own and enjoy by an otherwise ignorant fool who clearly lacks any first-hand experience with one. Under similar circumstances, I've done the same. It's frustrating seeing people ignorantly putting down firearms you like, and being an owner of a Taurus Judge, Mossberg 590 Shockwave, and a Smith & Wesson SIGMA SW40VE, I'm certainly no stranger to it. Heck, if anything, I feel like I ought to apologize to you. I was just goofing around, trying to make people laugh, I didn't mean to offend anyone. Honestly, I was actually intentionally trying to sound a bit like some of those obnoxious internet critics as a sort of parody to them.
