How thick does the filler material need to be?   Fill up the whole inside of that ball?  Will it always be the same size?   How firm does it need to be?  A little give, no give?      There's all kinds of types of foam that could be used as filler.  I was serious with the Great Stuff suggestion (because it really is great stuff  ;)  ).   She could get various types of foam and glue layers together and then shave it down to the desire shape/size.  Could even use different types/densities to control how much and where it gives, if that matters.    http://www.mcmaster.com/#standard-foam-sheets/=10lhzd8

    :hiding:       Wait... it's been how many years since I took thermo?  :dropjaw:    I used the wiki page too...  :angel:    All that calculus is just the "proof" (remember those?  :eek: )  of the equation used to calculate the thermal efficiency of the cycle.   As for that doodad, I'd be shocked if it was more about 10%. 

    My kids are little, having them run a couple blocks isn't realistic.  The neighbor's driveway puts the physical barrier of a tree line and a house between them and our house. 

The energy change through the cycle is proportional to the heat input and absolute temperature. Since the process isn't "perfect", the total actual energy change must be less than or equal to the total ideal energy change. What's not clear about that? ;)

Our plan is basically pretty simple as well....    If BG is not between us and the kids, I engage the BG, she gets the kids and calls 911.  If the BG is between us and the kids, I engage BG as necessary on my way to the kids, she calls 911.  If I can get to the kids and get out without engaging, I will.  Rally point is neighbor's driveway. 

The "Carnot II" might imply that its based around the Carnot cycle, which is a thermodynamic cycle that uses a temperature differences to accomplish work output of some sort.  https://en.wikipedia.org/wiki/Carnot_heat_engine

I've had shoulder issues since high school wrestling.  I've learned that I have to exercise and keep the surrounding muscles toned, because the ligaments and such just don't do a good job holding the joint together anymore.  There's specific exercises to target different areas.  A friend's wife is a physical therapist and recommended a few things, and they help.  It doesn't really slow me down, but I've also learned that there's certain movements I have to be very careful with or avoid altogether.  Most all of that learning came the hard way.   I've talked with several people who've had similar problems and had surgery to fix it.  The standard answer is to put off surgery until you can't stand it any longer.  The surgery is very painful, and full recovery generally takes an entire year.  The latest surgical techniques may have improved that.    Last time I threw my shoulder out, I was throwing a frisbee for my dog.  :wall:   Thankfully that's been several years ago.

Very situationally dependent.  Unfortunately there's no "one size fits all" solution.  Depends on how your house is built, where you are relative to "safe" exits, and whether you have single or multiple attackers.   I think the first choice would be to seek cover....  bullet-resistant cover.  So shutting an interior door isn't cover.  If cover isn't immediately available, the next choice is escape.  Moving targets are hard to hit.  But you don't want them running straight to the attacker's buddies waiting in your driveway, or falling down the stairs in their haste.    You've got to look at how your house is laid out, where everyone is likely to be, how an attacker (or attackers) might enter, and determine a plan (or plans) of action based on that. 

    That's basically what I meant.  He mentioned sub-MOA during initial shooting... so that should mean roughly 10" groups at 1000 yds.  That tells me that a good shooter (one who could consistently make sub-MOA groups at 100 yds) should find hitting a target 3.5x bigger than his group size relatively easy.  1000 yds is a long way and I don't mean to discount the difficulty, but it doesn't get any easier than a good rifle on flat range with no wind.

Pretty impressive, though I'm curious why no group sizes are included. A 9sqft target seems fairly large for a claimed sub-moa rifle.

Use Great Stuff for the filler.

Welcome!

    I've got two 15 rd mags for a Ruger and one 12 rd for my S&W 6904.  They all work fine. 

Mec-gar makes a lot of OEM magazines, so their version may well be exactly the same thing. I've got a couple of their mags and have had no issues.

I assumed gun show and online trolling was the whole point of the half billion tax dollar expense. As for following the money, my guess is they'll do the standard gestapo thing and threaten/charge anyone they can find minimal evidence on and hope the individual isnt willing/able to afford to defend themselves in court so they plea down and it still goes as a win in their column.

Welcome!

Have a look at this... http://www.overlandexpo.com/east   They've not got details up for the one this year, but I assume there will be one.  Lots of class and opportunity to learn how to go places without breaking stuff. 

    No, or only if you do it repeatedly and make money in the process.  I'm guessing this targets a couple groups of people....   1) guys who show up at every gun show with a table full of guns to sell but don't have an FFL;   2) guys effectively doing the same thing on armslist, gunbroker, etc.    They'll be trolling guns shows and online looking for the same people selling a bunch of guns on a routine basis.  How many gunsis too many and how often is too often?  No idea.  I'd presume the ATF already has some guidelines for such things. 

    If a TWRA officer happens by when you're shooting and you don't have a permit, you get ticketed/fined/arrested/stuff confiscated....  

Finally a real airshow!   :clap:     We've been looking forward to this since we heard about it a couple years ago.  They had parking passes for $25 before Christmas. 

Welcome!

Seems to me all he did was find a new way to spend half a billion of our dollars.

I'm not seeing what this is intended to accomplish...?  10,000 votes makes a much bigger impact than a petition with 100,000 names. 

    Refill valve?   :squint:     Google has educated me, added to Amazon wish list.  :up:
