I have shot my 270 using H4831 and Sierra 130 GK for over 25 years now. This combo has produced sub MOA at 100, 200 and 300 yards.
Sounds a lot like my load I developed this summer.




.......Although your .690" group is decent at 100 yds., it roughly should translate to a little over 2" at 300 yds. Still plenty good. What I want to see in person is the 300 yd. sub-MOA groups the other poster claims to be able to shoot with their .270.........

PAwildman,
1MOA (minute of angle)= 1" at 100 yards, 2" at 200 yds, 3'' at 300 yds., etc.

.......Perhaps I've been misinformed over the years...and someone please correct me if I'm wrong. I have always understood that MOA was approximately 1" @ 100 yds. It has been my interpretation that to shoot 1" groups at 300 yds., you'd best be shooting .33" or better at 100 yds. That is what I understand MOA to be for 300 yds.....sub 1".......???? And that is what I believed the post to read...."sub-MOA @ 300 yds."

Yes it is.
1 MOA (minute or arc or angle)= 1.047 inchesat 100yards, 2.094 inches at 200 yards. The greater the distance the wider the arc becomes.

If you were to draw an angle on a piece of paper you can see that the farther you move from the vertex the greater distance there is between the two lines.

A 1 MOA rifle and or load will shoot within 1 inch per every hundred yards in distance. At 1000 yards this would be a 10 inch group (10.47" to be exact).


you'd best be shooting .33" or better at 100 yds.
This would be a 1/3rd MOA rifle.

Yeah....you're right.... Don't know why I was thinking that at the time.... Simply got MOA and sub-1" groups at any range confused for a time...
Must have been having a "senior moment"......
