First sight in at 300 yards, with new barrel
 
I know there is no grouping to show, but my last 3 shots where all nice. the two bottom in the red and the one just touching the black center on the bottom where my last 3 shots. now its off to get my deer.

I will show some shot groups later on but this was my target after sight in with the new Bushmaster Varminter 24" heavy fluted barrel.

this was the first time this barrel has had a round threw it, and i will be getting some shot groups on the next morning that there is no wind or deer to shoot.

it may be a while but i know this rifle will impress.

when sighting in i kept over adjusting,,, guess its not a true 1/8th moa ajustment, that or my math was off lol

Whats your barrel twist. 1-9?? How light is your trigger pull? Nice looking rifle

at 300yds each click should move like .375inches for 1/8moa

i guess it was close then cause i was getting just over a 1/4" with each click

again, thats just guessing

set up a 100yard target shoot a group then move it 80 clicks up should move the group 10 inches. if it does then your close enough to 1/8 moa. its a good thing to know exactly what your click value is even on high end scopes.

at 300yards 26 clicks on a 1/8 moa should move the group 9.75 inches.
