I just built another AR15 with a Lilja S 16" 1:8 barrel. I am wanting this mostly for target shooting and the occasional varmit "dusting" I want something as accurate as I can get. I have read that the 62 and 68gr. bullets work well in this twist. Is there a different weight/type I would be better served with? I have been thinking of something in the BTHP Match or the Game King bullet. What are you guys getting the best accuracy out of? I have been away from reloading for many years and have just gotten all my reloading stuff unpacked and set up so I am ready to get started. :) I know there has been a lot of improvements in bullet construction while I was overseas so any feedback on your experience is greatly appreciated.
Thanks,
WW

My 20", 1-8" twist, likes 69 grain Sierra Match Kings. The 77 grains work pretty good too. For 55 grain stuff so far, it only likes the Barnes MPG.....so far. I've got more to try.

For my "match" ammo, i SOLELY use sierra matchkings. I would load up some 77gr's for that 1:8.

The Hornady 75 gr HPBT-M bullet is another good one for your barrel. They are accurate, buck the wind well, load to magazine length and are less expensive than MatchKings. They also do well in self defense ammo evaluations. So, what's not to like?

I vote the Hornady 75gr BTHP (OTM's) also, my 1:8 BCM 410 SS barrel loves them and it's only a 16" barrel, with 24gr of Varget(LC or Hornady brass, Rem 7 1/2 primer, 2.255" COAL) I shot a .4" 5 shot group just to check zero a couple weeks ago after doing some testing at the range with my 6.8, the .223 75gr load is a keeper for sure(I got some RE-15 loads to test also though).

Llija is one of the top five or so barrel makers. It will shoot any match bullet by any of the major makers just fine. Do you want the smallest groups at 100 yards or the smallest groups at 500 yards.

100 to 200 yards shoot 52 or 53 grain match bullets by Sierra, Hornady or Nosler.

200 to 300 yards shoot Sierra's 69 or Horbady's 68.

200 to 500 shoot Sierra or Nosler's 77 or Hornady's 75 grain HPBT match bullets.

500 yards and out shoot Hornady's 75 or 80 grain A-Max bullets or Sierra or Nosler 80's. These must be seated long and loaded one at a time. They will not fit in a magazine.

The different bullets are designed for different venues. The lightest bullets usually shoot the best at 100 yards regardless of twist rate.

My RRA NM4 (20" 1:8 twist) loves 53gr & 69gr SMKs - MOA 10 shot groups. It's OK with 77gr SMK, but the groups open up slightly - or I just haven't found the right load yet. I don't shoot past 300yards, hard to get further in east TN, so I use the 53gr SMK at 200 or less, 69 at 200+
