Hi,
I am relatively new here and haven't shot the 5.56 and the AR15 for a long time. So, need some advice on rounds. When I finally bought an AR15 I decided on the new gas piston type version, a POF-USA. So, I chose thier 'Recon' model with a 16" barrel with the vortex muzzel break. According to Frank of POF my barrel is ths 'CF' Continued Fluted Heavy Barrel with a 1:8 twist and has polygonal rifeling with heavy chromed lining. That's a true fact whith POF when it comes to a heavy use of chrome! He said it's just like Novaseki's barrels but not made of SS. Ok, this is a lot of info and comparison because I've seen and read a lot about Novaseki's barrels and there supposed to be on top. This barrel I have sound pretty good as well. I have not shot it yet. Time and the weather here has kept me from shooting this beauty.
My biggest question is bullet weight for the 1:8 twist barrel. So far I have a massed a good amount SS109/62 grn. rounds of LC and some Radway with a good amount of Black Hills(blue box) 68 grn. MHP, 75 grn MHP and several boxes of Hornady's TAP in 75 grn. HP. I need to buy some 77 grn. MHP but haven't put the $ out yet on that round yet. The Black Hills and Hornaday TAP will do fine in this barrel and the SS109 marginal.
My biggest question is about the 55grn. round, is it too light for such a tight twist of 1:8 and thus be useless for serious target shooting or just good old plinking. It's relatively cheap, more plentiful than any of the heavier rounds so what's the verdict on this this round with my new rig? My old XM177 Bushy with its 11.5" barrel and 5.5 muzzel break had a 1:9 twist at best and shot the older round and the SS109 with out a problem but wasn't a 1" MOA shooter either. Plus that was years ago that damnned AWB came into to law. Never Again!!
So, any AR15 vetrans advice would be great and espscially any POF-USA owners and thier choice rounds would be greatly appreceieated.
