Dpms a15 .223
Factory magazine is too short for the 2.295" loads that shoot really well in my Browning and Tikka.
Have ordered several new mags from ASC (2.318" +/- .002) that should handle the longer loads just fine. MSR (more politically correct nomenclature) chambers and shoots longer loads fine but have not experimented with different loads at the range yet. Question: What different loads have been tried; what were they -- did they different loads affect accuracy? This is my 1st AR. After shooting several rounds to fireform case to rifle the shoulder measurement was .005"/.007" longer than factory ammo or my other .223's. Is this normal? |

You will be hard pressed to find any mag that's internal length is longer then 2.270 . Do you have a link to the new mags you ordered ? I'd like to get some if the internal length is in fact 2.290 or longer , man that would be great !

Also be sure to FL size all your cases when loading for a auto feeding rifle . Neck only sizing is not recommended . One reason is you can actually have a fire formed case from your rifle that is actually a couple thousandths longer then your chamber . Or the body has expanded a tad more then the diameter of the chamber causing feeding issues .

The difference is in the fabrication of the mags. Space(OAL) is gained by switching the metal lap/weld from the front of the mag to the rear. In my case, the small gain in OAL did not make a significant diff in either function or accuracy.

Mobuck : I'm very interested in this mag . What bullets and amount of testing did you do . I have a NM service rifle I load 77gr smk for and would love to finally do some COAL testing . With the 77's You get what you get as far as COAL .
I'd agree I'd not likely see a difference in a 55gr bullet but I might with the 77's in my 223 Wylde chamber . If you've done a bunch of testing with the 77gr smk and found no benefit then I'll likely pass .
