This post will probably end up in the reloading section. I would adj. the gas regulator to the 175 gr . load ,because this is a gas operated system & not a recoil operated system. 1.5 grs. more of the same powder will produce a higher pressure , some what. You also have to take into account that a heaver projectile is going to be harder to move down the barrel & may produce the same pressure as the lighter ,higher charged projectile. Its why you have to test this stuff. Too many variables, type of chamber , barrel condition & such . Even powder type & primer type & case thickness, will give different results.

Same dimensions , the 7.62 may be a thicker case . I weigh all my brass & sort it that way . You may be surprised that even brass of the same head stamp (commercial or milspec ) may have variances in weight & that will change pressure because of the thickness of the brass its self.

I have not loaded or shot any subsonic ammo & don't intend to . Don't plan on any suppressed weapons or the ammo that they shoot . I like the noise & I ware hearing protection. <thumbsup>

I agree.

Kinda nice throwing out a .30 cal. bullet from an AR platform & not having the problems of a weak bolt or mags that don't work. So you want to keep it a total of 16" . I would stay with the carbine gas system , as Jgun said , you can shoot any bullet combo out there with it. Smith Enterprises makes a long & short .30 brake ( this short one & is on my 16" 300BLK & its 2 1/8 " w/nut ) . The gas system hole for a piston may not be different . You can call different bbl. manufacturers to see what they have done , that way you won't have to guess or experiment .

Well if its not a rule , it should be .

Full length size them at a minimum, for semi automatic action rifles. I use small base dies for my 5.56 & 308 , but I use my brass in a lot of different rifles . Follow the manufactures instructions for your dies , to adj. sizing die. Careful how much you back off a sizing die . Do you have a case gage ? They are good for checking cartridge case head spacing . You just got lucky with those two different weight bullets ,at that distance.

Not sure what you are asking ? You can have any barrel made in that caliber , in just about any form ya want . Is there some thing different with there piston system ? If your asking if it will function , as long as the barrels gas hole is sufficient to do what it supposed to do , should have no problems . We both know this is a new caliber (some what ) & the proper set up is there some where for this caliber, for piston operation. Can we say, adj. gas regulator .

Mine asks if there is any thing she can help me pack. I don't get too worked up until Nov. .I only hunt gun season in Ohio, because I don't live there any more . (Long drive ) Just because you have food for bait out there doesn't mean you will see any thing come to it .

Sun shine state.

Now , that's a heavy bullet, let us know how it shoots & what's the COL on it. <lmao> Sorry ,I couldn't help it , we know its a typo.

Check the reloading section for some of the ones I have loaded . 125's,150's 135MK's . You will also see some that are on the over pressure side(and I said so ) & they may give you some limits & also I chrono'ed results also. Its been so Hot ,you can fry an egg at the range & I have two rifles to test this week ,if we don't get much rain from Irene. Hay, it might cool it off ,but we are expecting 30-40 mph winds & the bitch is missing us .

You can use the Dillon 550B as a single stage or progressive. I do it a lot ,because I size & deprime my brass before I clean it . I also hand prime all my ammo . Nothing against the priming systems of loaders , I like to feel my primers seat. I also taper crimp in a separate operation ,mostly on my single stage press.I like to feel it also. Just the way I do things . The Dillon makes quick work of the sizing operation . The single stage is a good idea ,but as said you can set the Dillon up & use it as a single stage .

Most likely fell out during assembly. You can tweak those pins ,so they stay where you put them .

The question was ,how much cyclic weight is too much. Well ,my answer would be to take your rifle (with all the added weight ) & dump it in the water ,mud & sand & see if it works . Than , take it to oh ,somewhere where's its around 0 deg. F. for a couple of days & see how it does there . My point is all this stuff works on a range queen ,that's pampered with cleaning on a regular basis ( and that's OK ),but in harsh environments ,they will probably malfunction. All these systems for the AR type rifles have been tested to work in most all conditions & environments. If you are setting up a 5.56 to shoot like a .22 LR , it can be done ,but does have draw backs, depending what you are using it for .

You will need a special receiver set made . There are 30'06 versions around some where ,but that wouldn't be large enough ether. The barrel wouldn't be a problem , but the buffer & spring would have to be tested (Tubb's spring ?) BCG would also need testing or you could get hurt. If you have enough $$ , I'm sure you could talk a manufacturer into making a receiver set for you, but the testing would also get expensive. I'm cleaning two 300WM Browning Bar's , at this time ,so it can be done to a semi auto. You just have to do R&D on the components.

Shim set & blue loc tite.

Could be ammo , some rifles just don't like sub sonic ammo . What's the round count ? New build ? As said ,may give problems until you get some round count. How well lubed is the action ? You made a custom spring for that set up & it may work fine with super sonics , only way to know is to put some of it to work in your rifle. Make sure your gas block is correct, some are set back the thickness of the front hand guard guard cap. Using AR 15/16 buffer & spring ? Not 308 parts .

Rear of the receiver looks bent to the right on the bottom . It can be repaired ,but might take some doing & $$. There is a welding jig , some where ,if I remember correctly, for AK's . Might help. With out it being in my hand , its really no way to be sure . I would disassemble the rifle & see if its out of square ( which it looks like ) . What's the history of this rifle ? Is it a build ? Was it re barreled ? You can blast an AK all day long & not hurt it ,of course they have ware items ,like any other mechanical device.

Bro ,if you want me to send you some of my Rem. brass ,PM me, I can part with some . I like the cut down LC better any way . Its had two loadings . You know all you have to do is buy some of the subsonic 220 gr. loads out there to get some rem. brass & I'm not sure it will fix your problem.

Patience & hard work .

The brass in that photo had a black slimy stuff on it & washed off with warm water & dish soap. The 30'06 I just did came out like new brass . I have not got the proper light to show just how nice it came out , but will keep trying .

Crush washers (if you do indeed have a crush washer & not a peel washer ) You tighten it up & then loosen it & tighten it up again & do that process until you get it to where you want it , to a point. & I hope you have your barrel in a blocked vice to do this.(barrel blocks )

Annealing brass makes the brass softer for repeated expanding & resizing. Firing brass work hardens it ,so annealing softens it up a little so it can be reworked . You can form the brass than anneal it , might work out better for ya. I have heard of some people using a stepped process to make the case to a .30 cal . , they used different dies , in a process to do this & I don't remember what they were. It looks like your bullets are in the case far enough . You can have high pressure by seating a bullet too deep , but you would see high pressure signs on the case head & primer. You can anneal your brass at home before you form it , its not that big of a deal. Just look it up , you can do it with a propane or map torch & a tray of water . Turning the inside of the neck may cause problems with bullet tension. You know what you are trying to do is on the border of this cartridges performance levels & may need special considerations as far as case forming , as in annealing , which you are aware of . The velocity swing may have been the split brass rds..

I have about a 100 30'06 brass cooking right now , we will See & I will take some photos in better light . The last ones didn't show the difference too well .
