NEW SIERRA GAMECHANGER BULLETS COMING TO MIDSOUTH SHOOTERS! AUGUST 22, 2018 DUSTYN BREWER1 COMMENT When a new projectile enters the reloading market, it’s a pretty big deal. It’s always exciting to see innovation coupled with precision, and performance. The GameChanger Bullets, a new offering in the tipped GameKing bullet line, are touted as the “…perfect blend of exceptional Ballistic Coefficients (BC), Accuracy, and Deadly Terminal Performance on tough wild game.” The bullets feature a synthetic tip for smoother chambering, improved flight and better expansion on target (game) impact. The open pocket design below the poly-tip further expands the lead core, while the precisely engineered jacket wall concentricity makes for an incredibly accurate bullet. Tuned ogive for industry-leading BC. Boat tail design creates stable flight and accuracy. Open pocket (Hollow Point) expands lead core instantly on impact. Precisely Engineered Jacket wall concentricity ensures accuracy. Wall thickness controls expansion and retains weight For individual bullet info on the Sierra GameChangers, check out this article at Midsouth Shooters!

I also floated my Pacific Press Shell Holder , though I pretty much only use it for tools now , since I got the MEC . I found that a Forster Match Seating Die & the MEC Marksmen Press , with its floating Shell Holder, all loads are 0.001" & under , some don't even move the Dial Indicators Needle & I check Sized Brass & Loaded Ammo . I clean my Dies before each use , my Redding Bushing Sizing Die before I use it & leave sizing Lubricant in it when not in use for rust or corrosion resistance .

Sources in California say that radical Muslims are planning to kill every U.S. citizen in Los Angeles. Police officials fear the death toll could go as high as 49.

Yes, I use Tempilaq , as he does .

Same product I use . I'm sure you set timing with your machine , great job on that machine , very efficient , wish i had something like that .

How do you know what temp the necks get ? Is there water to quench the brass in that container ,to stop the heat of the brass traveling to the base ?

This is keeping me very busy , a project that I was asked about ( He didn't know I was already researching for it ) after playing with my SAI Plastic Stock , strengthening it with Carbon Fiber .A CF Hand Guard for the M14 type Rifles . I picked up a USGI Ventilated HG , because I thought they looked good , well I was disappointed in it as soon as I unwrapped it , it looked good & in decent shape , but is the flimsiest POS that ever was installed on a US military Rifle . I knew if I wanted to use one on my Rifle i would have to make it better , first I thought , just add a layer or two of CF , for strength , but thinking it would be easier to just make a new one . Well, its harder then you think , though I have some working prototypes , trimming them is going tom take some special tooling , to get them trimmed right . The photos show a mounted prototype solid HG , no Vents , because they not only look different , but cutting & trimming for the Vents in the HG , as said , need special tooling to do them right & I don't want to test the Vented type till Vents are cut .Also there are some imperfections in the Prototype because of the Vacuum process gave me some issues & also trimming , as said . I have over came the Vacuum issue , so as soon as I get the proper tooling will produce a much better HG . CF next to the modern heavy Plastic I used Kevlar for a bottom layer for heat suppression from the Barrel , crap is hard to cut even in its Fabric condition , so , unless I can find an easy way to cut it , I will use something else. How the prototype looks with various Stocks . As a side note , I stood on this HG with no ill effects , I never realized this crap was so strong .

So you are saying that if the hole was bored straight down with out an angle & placing the Pin in the exact same position , it wouldn't work ? You do know the Hole diameter is quit a bit larger in diameter then the Pins Out side diameter & it floats in its Bore , so no matter what angle you make ( 6 degree's is not very much ) it will move forward with Buffer /Spring pressure & it will do it no matter what its Bored at . The Receiver Extension actually keeps it in a somewhat straight up angle , with the over bore being as it is , when pressure is on it from the Buffer/Spring it does tilt a little forward , & its not because its bored at that 6 degree angle , its because the Bore is larger then the Pin & it tilts all by its self with out any angle , the only thing that keeps it with in a certain limit is the Length of the Pin its self . You'all have you thoughts on it & I have mine , lets just say that & you'all go about your repairing & figuring out all this Gunsmithing stuff .

It was mentioned that it was possible that the Buffer system might not be working because of no angle in the Bore of the Retaining Pin , thats not true , if it had the same placement , but true vertical , it work the same as if it was bored at an angle , thats the only reason I mentioned this whole thing . its not bored at an angle for any function of the Buffer system or its retainer , its Bored at an angle for pure manufacturing ease , thats what i said . For someone to say its not working because of it not being at an angle is baloney , as long as it is in the correct position to achieve its purpose . If anyone believes its bored at an angle for an operational purpose , please show me the documentation .?

You guys miss the whole point , if bored directly straight from the top , it would be in the exact same place , the difference would be that you would have a hole in the Receiver Ring . its bored at an angle for purely manufacturing ease & cosmetic's , because it not only would look funny with a hole in the Top of the Receiver ring , but also in may weaken the Narrow area of the Receiver ring . Also the Bore is somewhat of a loose fitment for the Retaining Pin & when the Receiver Extension is screwed in , the Retaining Pin levels with the bottom of the Extension , until the Buffer contacts it & it then will canter slightly forward ,because of fitment & Spring Pressure . Thats all the Pin is for is to hold the Buffer in the Extension while the Upper receiver is separated from the Lower . & I know you'all know that ? Probably will not find any photo's now ( but I will look , just because its you guys ?) , but some real early after market prototype Lower Receivers were actually made with a notch at the top to the Receiver Ring for boring the Retaining pin hole & I believe they were doing so because of Patent right infringement at the time or thought it was a better way then Armalite's manufacturing technique & of course they are history & never went any where.

Ok & whats your point , where is that going to change its location , if bored straight from the top & not at an angle to miss the Receiver ring ? Spec will be the same , only there will be a notch or hole cut into the Receiver Ring to bore it .

I just fitted the Receiver & Trigger Group today , had to file some of the Stock Liner where the Legs fit into , that took about an hour of lightly filing & checking fitment . The Stock Liner also had some metal protruding past the Trigger Group Pad seating area & I had to file that down for the TG to lock into the Receiver . Have no plans on Bedding the Action , I want the Rifle completely serviceable , its not going to be a Match Gun or a Bench Rifle that is almost never disassembled , so not to disturb the Bedding .Now the rest of the things you mentioned , like a Unitized Gas Cylinder & I have three different Pistons already to test for it , but the Barrel is next .

I dont believe the Buffer retainer is spec'ed to be at a slight angle , its the easiest way to bore the hole , with out having to bore through the Receiver Extension Threaded area in the Lower Receiver , see drawing . Boring through the Extension & making it a straight hole & not angled , would not change the orientation of the Buffer retainer . The 10 1/2" Buffer Spring length that was described seems a little short , nor was a coil count described . Mix components from retailers or manufacturers , who have no idea what an AR 10 or a DPMS LR 308 are or their differences , is what is getting a lot of builders in trouble , not the individual systems . Good to see the Rifle running well , enjoy !

Slowly but surely , a Barrel is next .

They probably were not allowed to have one , they might hurt someone !

I thought the same thing , but with all the pressure on LE since O'Buttheads time , they want to use non lethal ways to apprehend someone . That poor women was caught in a Frenzy shooting it seems , they had there chance from our perspective , but were reluctant till someone was in danger & too late , sometimes LE just cant win , the way they are pressured not to open fire . I'm sure they are not feeling too good right now about how it turned out , unfortunately .I'm glad I'm not one of them . Of course this is in Commiefornia ,

This is kinda a strange shooting , PC madness is what let this play out , me thinks ! https://www.infowars.com/shock-video-lapd-guns-down-knife-wielding-suspect-hostage/

New Rifle , contact DPMS for Warranty work . They are bad photo's , hard to tell , I think you need more light , maybe take a photo outside . The Rear sight or Receiver ,seems to be cocked to one side . You might want to remove the Hand Guards to get a better view of the Gas Tube & Barrel , it may help in determining what is going on . This is how I checked a Factory Colt that was sightly out of alignment. Using a Laser.

I have their T 3 Gas Cylinder Lock Wrench , works with the M14/M1A & M1 Garand .

Most say a 16" 308AR barrel with a rifle length gas system will not work also. Your right , DPMS went about the Buffer system a different way to get around Armalites Patent or their threat of a law suit. I'm also sure Clint knows a lot , but he is also selling those heavy Buffers , what did you expect him to say !

Just picked up a Walnut pre-Boyds SAI Stock with out the selector cut , I didn't want the Cut in the Stock , after all its not select fire , it will be in the mail today , picked up NOS Flash suppressor/w Sight , Gas Piston & some tools , for this build . I will post photo's when the Stock gets here . I'm looking into Barrels now .

Whats in the Baggie's , complete parts kit ?

Where is it that I said Mr Stoner was wrong ? Just more then one way to accomplish proper operation . There is a lot that goes into what weight Spring & there lengths is correct for proper function of a DI operated Action , its a balance of components . I never said there is one way better then the other , you are , I just pointed out , it might be an easier way to get the rifle with the correct components to see if it takes care of the issue he is having . I don't care one way or the other which system he choses , I'm not an Armalite pusher or a DPMS , I don't bow to one or the other , they both work , thats plain & the amount of DPMS LR 308 type Rifles out there prove it , I would be safe to say , thousands more then AR 10 in the same configuration ( Carbine ) , so to sit here & say that the Armalite system is superior to the DPMS system , is not proven by any facts . That is Stoners design & DPMS is DPMS's design , you cant say they don't work , you can only say you like one or the other . ?

Why is it too light ? Its matched with a stronger Spring , its just a different system , works fine in tens of thousands of DPMS LR Rifles ., just like the Armalite system does , just two ways of going at it . They are both fine , when the correct components are used . DPMS 308 Carbine Buffer - $ 28.95 , 308 Carbine Buffer Spring - $ 5.99 , my math is not good , but thats around $ 35 .& you don't have to disassemble any thing , just pop the Buffer & Spring out . Armalite has their Buffer system for $ 55 , which does include the Receiver Extension , Buffer & Spring , End plate & Castile Nut , but all you need it the Receiver Extension , Ok I'm sure they are in stock somewhere .

Or get a DPMS 308 Buffer & Spring & leave the Receiver Extension in place .
