Nice setup. Is there adequate eye relief? With my Leupold VX-III 3.5-10X40 1" tube, I needed a forward cantilevered LaRue Tactical LT-104 scope mount (for 1" tube). For this scope I needed the eye piece further forward than yours for adequate eye relief. The ARMS 40-L low profile BUIS clears the eye piece with only 2mm to spare.

What kind of trigger do you have, as it can limit accuracy. I have a Rock River Arms two stage NM trigger group.

Performing a rough sighting in with my laser bore sighter, there was a lot of parallax at 20 yards. I read the manual and my scope is designed to be parallax free at 150 yds, so all is good.

hello guys here is how my setup groups at 100yds..We were trying to hit an apple i found at 300yds and had no luck hitting that darn thing, there where 3 other guys with high caliber rifle i think a 338, 270 and a 3006 that tried to knocked that apple at 300yds with no luck but the guys with the 338 let me shoot his rifle at 450yds and i hit the plate no problems, i can't figure that one out..(they all hit the plate at 450yds)..I only hit once with my AR..

Looks like pretty good shooting to me.

Maybe you really did hit the plate at 450 yds. The lighter bullet would not make as loud of a noise so you probably just didn't hear it! ;)
