It all depends , as said, on the distances you are planing to shoot. All the available will shoot good out of the 1-10 , but some don't do well at the longer ranges. That's where the 168-175 gr. bullets will do better . Not saying you can't group with the lighter pills at those ranges , just the heavies will do better . Just load the 155's or 147's or what ever at the reloading manual spec's & go from there . Just check your brass for signs of over pressure , as you would normally & if you have a Chronograph , use it to adjust as your load as needed. If you need loading spec info , go to the bullet manufactures sight & there should be some there.

Interesting .

If our politicians did drugs as much as they drink alcohol ( like they did during probation ) this would be a non issue today .

Got a 300BLK case holder for this trimmer from Midway , can't wait to try it out this week .

You can also change the buffer & or spring to lower felt recoil & make her run smoother (heavy buffers ) with the heavy's. With the short barrel , you may need to stay with a lighter bullet if you want the Vol., if that's your goal .

As said above , you can load up an AR 308 more than a M1A or for that matter the M1 Garrand. They have special loadings for the op rod rifles , but the AR 308 can be pushed . Just follow your normal proceedures for case inspection for problems. I push mine a little on work up loads . Be safe

I hope so .

Sounds like you have a burr in the lower"s slot for the bolt catch . Look in there with a magnifing glass & good light. The pin & set screw would cause some problems ,but as was said a good magnet will probably pull the pin out . You really need to try the magnet ,because I will be getting one of TM's lowers here shortly. <thumbsup> I polish all my catches (and just about every thing that moves ) to de-burr them & cold blue them when done , you can't see the catch part that rides in its slot any way.

Not sure if there is a DPMS type pre ban mag. , maybe the early AR 10 mags ? DPMS & others sell 5 & 10 rd. mags , for those commie states & then there's the bullet button or what ever its called , so you can't use the mag. release. Depends on the state.

Most gun or probably any manufacturers CS rep. will act "matter of factly" ,Your not the first to call about a problem. They get them all , all day long.

You guy's are stopping my heart, stop it <laughs>

Most do not even bother with that measurement because of mag. COL restrictions . Now with bolt action system you can work the COL . I would say every bbl. chamber will be some what different , I use the bullet that shoots the best . May not be scientific, but once you find the right bullet & load , ya got it made , but of course you knew that . If this was a bolt action forum , you would probably get all kinds of answers . With AR's you don't have a lot of COL options.

The Magazine will most likely determine the COL ,some will let you get away with a little more length above the 2.800" & some may jam in them mag. over the 2.800" . The magpul's are a little generous , of course if your loading one round at a time this means nothing . The chamber dimensions will also determine the bullet jump ( 308 vs 7.62 x51 ) or who made the barrel .

The dents in the case are caused by your bolt slamming into the partially fed cartridge on the feed ramp ( bolt lug marks ), from short stroking or it can be a magazine problem also . Looks like you took care of the short stroking ,lets see if it eliminates a potential mag problem also .

Ya , keep that upper assembly & build another upper assembly , the way you want it & you have two rifles. See , were here to help. <thumbsup>

Well I prefer the HB of the two . If you look at the weight difference , its not much at all & the SS HB , IMO ,will shoot better. They will both shoot just fine.

That ul learn ya , you started it, not me ( this time ) <laughs>.

Lets try to keep the shooting of others out of the discussion .

AR 15 & AR 308 take the same trigger groups. Some AR 308's do not like light hammer springs though , but you will find that out on the range & easy to replace, if its too light.

I assume the hand guard is a one piece unit that includes the barrel nut . I have seen them have bad threads or miss aligned threads & or barrel flange face.( Long shot ) I would call the bbl. manufacturer & see what they say , never know . I would inspect the chamber & rifling , could have a screwed up chamber or throat. Like was said , a lot of things could cause the problem . Fulton barrels are top notch in my book .

Get the round count up, as said & use good lubricant . 500 rds at least for break in . Any idea where the brass shavings came from ? How does your fired brass look ?

I do like the look of that hand guard.

I guess Colt is not going to lay down & die . I'm glad , just can't see paying there prices ,but nice they are out there going for it .

I like the chrome ones myself , but the unchromed ones work just fine .

Ya, but try to find them . Last time I looked SI was incommunicado & midway was out of stock . The S/S SI pins are much better than DPMS , post a photo of the FA one for comparison when ya get it ,please.
