What barrel contour are you guys using for you hunting rifles? Itd be for about 500yds max. Is that possible out of a 20inch hbar profile, will that get the job done? Im looking for 3/4 moa or tighter using factory hornady ammo

I have a Lilja 319 profile on my hunting rifle. I don't shoot out to 500 yards, but it's nice to carry and it shoots much better than I. One day I'll stretch it's legs.
I believe Adam Lilja reached out and put one down at quite an impressive distance last year. His rifle was listed for sale a while back, the description may have the specs. (Adam's barrel is listed as an AR-740)Last edited by jim_bob; 10-08-2015, 02:16 AM.

I like the Lilja Lightweight Wasp profile personally. I'm even thinking about dimpling the fore end on one. Steel quality to me is more important than profile, as higher end barrels with good grain structure seem to hold a group well even when heated, whereas many medium contour factory barrels will walk with heat, and featherweight rack grade even more so.
Adam put a large Montana deer down at 502yds with his 20" Grendel, and others have done the same out East and on Kodiak Island, AK.NRA Basic, Pistol, Rifle, Shotgun, RSO
