ok guys here it is..went out yesterday and did some function testing and today did some ladder work..so here goes and some interesting results
yesterday it was really windy but i thought it would be a good day to do some funtion test...so i stood in the driveway to do this so i could see exactly what the brass was doing.....
1st round. 1 load in mag only thing changed was the extractor defanged and polished...ejected at 2:30-2:45 ...bolt hold open...hmmm
2nd round. 1 loaded in mag and i added the 2.3" linier comp...case ejected at 1:30-2...hmmmm...really
3rd round. 1 loaded into mag and ...i added an H2 buffer...case ejected at 4..bolt locked open...hmmm
4th round. 1 loaded into mag...same set up as round 3...case ejected at 4 almost exactly in same spot as round 3...bolt locked open...i really wasnt expecting what i got here...but today i ran with it
everything i did was 1 thing at a time added to the previous set up
it is a little windy today too so i moved the target out to 75yrd insted of 100
i shot 35 rounds of verying flavor and the gun ran great...not one hiccup .....but it was about 55-60* today ...i want to try this set up at a colder temp...maybe in the 20's...i hope we get a day or two to try this out..but i did make it a point to run some of the 95gr loads and they ran perfect too...not a thing to complain about ejected and locked open on everything i shot today...so i dont know what to say here...was it the extractor?? or that i added the comp?? i will say i think the comp did give me more gas to deal with...it showed in the ejection angle...that is the only real things i changed, except for the H2 buffer and i really didnt expect the bolt to lock open with it but it was showing over gas to begin with....and it was not showing that before....all the loads were the same for the test.. and the H2 put the cases right where i wanted them to be...very consistat toady
also i will say that the gun really likes the sierra 105 blitzking and AR-COMP....wow it reaaally like that combo...and the AR-COMP was showing good groups with the sierra 120 pro hunter bullet too....maybe the comp on the barrel changed the harmonics of the barrel to the good, and bumped the gas up for a dwell bump...not sure, but i tell ya that 105 made a little pencil hole for 5 shots...gona put some of them together again to make sure it wasnt a fluke ...the 120s did good too with a nickel or maybe a little less size group....was a good day..and i needed some trigger theropy...rifle ran really good and got some dang good groups
i was really surprised at the results i got and how the rifle ran..it never missed a beat...so we shall see if it was fluke today or not and a run in some cooler temps is on the plate
