I find it interesting your Case Head Space Gage passed the Brass before . If your case gage is not to believed , Chambering & Extracting is the only alternative , besides checking the Cases on another gage . I used the Chambering /Extraction method for many years with out issue , till this year with Military once fired brass & not my first time with that type of brass ether . I did look up the instruction for the Hand Press . I can tell you , it doesn't take much in the form of Shoulder set back to cause an issue . As I alluded to before , some Shell Holders cause an issue with not enough Shoulder set back , no matter how you set the press up . Bottom line is , if Factory ammo works & your Hand loads don't , its your reloading process , in one form or another .

The story never did mention any type of ammo change to see if it was ammo related . I see a bunch in the comments section also spoke of ammo as the probable cause of this issue . I think there is more to this story !

Or if the rifle was stored in an air conditioned space ( home , Auto ) before the range ,its possible it could be condensation formed when brought out into the heat . You need to first actually determine what it is , water ( moisture ) or separation of the Lubricant as described above .

For function testing of a new build /Rifle or upgrade, I would want the best known cycling ammo I have or know, only because you are function testing components , not ammo . If you put some cheap ammo through a new build & it has issues , you will be looking at not just the rifle components for causes , but them & the ammo, best to eliminate one before you even begin , that way you know their is a better chance of a component issue ,or mechanical issue , then wondering if its the $hit ammo . Plenty of time to play with the cheap fodder later to see how it functions in a known functioning action .

It could have been I agree , its a hand held Lathe & Milling Machine in one , if used correctly Spell check sucks !

I went in the one around here & was not impressed with any of the deals . I was in there last month & I think they had better sales , but their stuff is all over priced anyway .

Its that with both W & E in the Rear Sight , you don't have to reach forward to make a separate adjustment , it can all be done at the rear sight . A little more convenient , its why they designed the A2 rear sight .

You people that live there , need to take your State back from the Commie's http://www.breitbart.com/california/2017/05/19/ca-democrats-working-60-pages-assault-weapon-regulatory-changes-behind-closed-doors/

I made my own feeder paddle & its been working for about a week with out a Jam , something the originals never did . It seems to throw it farther out also . I made a pattern & marked it out on some galvanized Sheet metal I have laying around , cut it out with my Dremel Tool ( Robocop would be proud ) & bent it on my Vice , centered a hole for the screw & checked balance like I do for my Drone prop's & away its been going . I think I made the tolerances a little tighter & no Corn has jammed yet . Now lets see how long it works

Try both Brands if you have not added that extra 1/4" to the set up , which is in the instructions , I looked at them yesterday . Even if it doesn't cam over , the extra 1/4" makes sure you have room to take up any play in the Press & the proper Shoulder set back . If you have time , see what I went through with my new MEC Marksmen Press ( its here in the Reloading section ) , It doesn't have a compound linkage for the Ram , like most single stage presses & I set the Press up to touch the Shell Holder to the bottom of the Die & I had the same issue you have . I thought there was no play in the straight Linkage ,because it will not or can not , Cam over , but there was a little play & it was just enough to not set back the shoulder properly & I'm only talking about a Thousandth of an inch , very small ,I thought the Shell holder was touching the bottom of the Die , but wasn't , I had to force it just a little to fit the LE Wilson Case Gage , that I bought later to make sure it was right . I also had to find the right Shell Holder for me to do so also & it was a Lee I had , the Two RCBS Shell holders , I have ,will not permit the case to be set back enough . I did trim one about 0.004" that works also .

Nice ! Ya, windage & Elevation would have been nice in the rear sight .

I like those two songs & I'm an old fart . Always makes me wonder what goes through anyones mind to kill them selves , such a waste of talent .

Try different manufacturers Brass first . I just re read your first post & read you set a much shorter COL & it did the same thing , so probably not the COL , I load mine about the same COL . Starting to sound like a Brass issue , but still , I would look further into the Shoulder set back .

-Too long of Cartridge Overall Length for the Chamber -Your Brass needs a Small Base Sizer Die , try different manufacturers Brass -You may not be setting your Press up correctly , are you setting the press Ram so the Shell Holder is touching the bottom of the Sizer Die Body when sizing the Case ? The instructions may not say this , but its a good way to make sure you have the proper Shoulder set back . I have trimmed down RCBS Shell Holder for my MEC press , I have a Lee Shell Holder works with out trimming or cutting down . Believe it or not , all Brands of Shell holders are not made to the same spec's , close ,but not all the same . -Sized , Trimmed , unloaded Case should easily chamber & extract .

They are still out of stock

Reads out of stock !

Just ordered Ramshot - X-terminator Powder Hodgdon -H335 Powder And Speer 87 gr. hot core Bullets We will see how these work also . I also used some Remington Bench rest Primers , just for comparison to the CCI's .

That can happen on a small case like .223 , pretty hard to do on a 308 , but anything is possible . I would size a Case & with out a Bullet & see if it chambers & Extracts OK , that may tell you something about what is going on . If the empty case has an issue , then you know its a sizing issue , if it feeds & Chambers & you can unlock the Bolt normally , you need to look elsewhere .

This issue sounds like the same thing I got when I bought the New MEC single stage press last year , & found I was not setting the Case Shoulder back enough . I now use LE. Wilson Case Gages . Even though I reloaded for almost forty years with out them & never had an issue till I got this new Press , I had to find a Shell Holder that permitted proper Shoulder set back . Might also be you have some play in your Press & its not forcing the Shoulder to the proper set back . You gage may not be telling the whole truth & it wouldn't be the first time . The Lee Had Press is a Great little tool , but may not be for a Large Caliber case . Just one more thing to look into .I just read about someone had a Hornady Case Gage that was showing incorrectly .

This is some Port sizes for you to ponder for the 308 , which would be close to the 243 & are used for the 243 also . I guess if you had an 18" barrel with a Carbine Gas system , you might of been OK . Oh & these are secret , so you didn't see them ! DPMS LR-308 Style Rifle 18" rifle 0.308 0.0960 18" car 0.308 0.0635 16" mid 0.308 0.078 16" mid 0.308 0.081 16" car 0.308 0.07 16" car 0.308 0.073 16" car 0.308 0.076 20" rifle 0.308 0.0935 20" rifle 0.308 0.096

First its a DPMS G 2 & this new platform from DPMS has very little in the way of after market components available for it , its a down sized LR 308AR . From what we have been reading , it's a good shooter as is , be as has been said , stock triggers ( Fire Control Group ) on just about every AR rifle you purchase from the factory has a Lawyer built into it .Most are horrible for any kind of precision work , the FCG replacements mentioned will make for a more precise control with out the Creep, grittiness of most stock FCG's . You may like the Factory FCG , but a FCG upgrade can do wonders for group size for most shooters . Get used to the Rifle for a while & Optics will make for a more precision shooter also . Most Scope Mounts are not all that good for using the Iron type sights on your rifle & have the scope mounted at the same time , unless you use a Red Dot sight or something similar to be able to sight through it with the Iron sights. You only have twenty rounds through the Rifle , run some more Ammo through her , try some match 168gr. ammo & see how that works , these big bores seem to all run well with that weight of bullet . As far as a Thread or something for beginners , this Forum is full of them & you just started another one . There are some Threads on the DPMS G2 around here somewhere .

If it fits correctly into the Case Gage , yes the Case is sized correctly for case head space. You should always Trim the cases to Trim length , you can get away with out doing it in some Chambers , but you never know with some Brass & its thickness after sizing . Another thing is , what Sizing Die do you have , Full Length or Small Base ? A FL will work in most cases , but not all Chambers are a like , some fired Brass , from some manufacturers may not Size the same & need the SB Die . Size & Trim a Case & Chamber it & see how it reacts , you can also try one of your untrimmed Cases also. I load a lot of 155gr. Hornady match Bullets & as long as they are trimmed & the Shoulder is set back correctly , your COL is fine .

You will get Bolt Locking Lug marks when cycling loaded ammo with out firing it , Bullet scraps along the locking lugs on the way out . Trim Brass to 2.005" & make sure Bolt locking Lugs are well lubricated . If rife is new Build or just a new rifle , things will be a little tight . Needs to seat components in. Was Head Space checked or is a factory rifle ?

A proper size wood dowel rod in the Barrel when drilling is a good safety stop for the drill bit . Also if you have them or barrow them , a drill index set will get you close to a measurement on what you have & also do one step at a time , till you get what works & it should not be more then the measurement Robocop stated. Just seeing what Gas Port size you have may give some answers to what is going on .

Not even sure those numbers are correct , I did get one or two & in some loads ,three in a row that were all with in a range , then I would get a reading of 4600+fps & that screwed all the ES & SD up . Magnitospeed instructed me to adj. the sensitivity setting on the the program for the smaller Caliber .That could be why when I tried it once on a 5.56 bbl. , it was wacking out the same way . The 3031 & 4895 are not going any further , they are slightly compressed load already ( maybe with much lighter Bullets ) . I'm not going to pursue those Powders any further with this Bullet. The WC 846 seems to show it going in the right direction .
