First Range Trip With My AR

<< < (2/3) > >>

Glock 1:
Hey Wildgoose, If you're looking for a great load for CMP. Try 24.5gr Varget with a 69gr Sierra MKHPBT. Those 1x8 twists seem to love these!

Installing a peep rear sight and getting a smaller width front sight will "tighten" things up a bit also.

I de-copper my CMP AR (RRA) after EVERY shoot! Copper buid-up kills accuracy!  Copper solvent and a few patches are pretty inexpensive for getting that copper out, keeping your accuracy and extending your barrel life.

Keep shooting!

I showed your new rifle to my wife and she was not convinced that I need one.  I think she considers you a bad influence.  :)  Maybe I should come back from that KC gunshow in January with a new toy just to prove her right.

Wildgoose:
Back to the range with a diffrent scope and some handloads using the Serria 69 grain MKHPBT. No loose mount this time. Shot five diffrent loads using RL-15 powder. The starting load came in at 1.75" for ten shots. As I ran up to the max load things shrank down to 1.25". Now thats some better from my first outing. I did retest some left over 55 gr factory Remmington that shot at 2.50". Yep, its true, 1 in 8" twist does not like the lighter bullets. I still need to finish up with the break in routine on the barrel and the stock trigger I have in this rifle leaves something to be desired. But I think things are on track for getting into some entry level match shooting. Next time I have some loads using the same bullet and Varget.

Glock 1:
A good recipe for the 69gr MKHPBT is 24.5gr Varget.  If you seat the bullet just deep enough to load into a AR mag you'll get amazing accuracy out of your rifle!  It took 3 different people at our CMP matches to work this load up and we get sub-moa accuracy with 1X8 twist barrels!!

This is NOT a max load but when seating the bullet you'll get very slight "crunching" of the powder due to the elongated/cylindrical form of Varget and .223 case capacity-this does not affect the loads that we can tell and provides the best accuracy!!

bkoenig:
I do 25.5 grains of Varget with a 60 grain Vmax and I get some slight powder compression also.  Accuracy is pretty good, but this is out of a Savage bolt gun.
