Default Regular Axis vs. Axis FMJ

We are having the first really nice day in almost 10 weeks today. Sunny. No wind. Upper 50's. Went to the outoor archery range at the State Park this morning and did some long range shooting. Have been shooting the Aixs FMJ's for about six weeks now, and did some comparison between them and the regular ST Axis -which weigh about 26 grains less. I know there are lots of charts out there that plot the trajectory of an arrow, but they don't seem to work out in the real world at the range - probably due to the fact that the sights are about 3.5" above the arrow - and the arrow is rising relative to the sights until maybe 18 yards or so.

I had already noticed, in the backyard, that the FMJ's hit about 3/4" below the ST Axis. Fairly insignificant. But at 40 yards, the two arrows group just over 4" apart. And at 50 it opens up to over 5". At 60 yards it is almost 7". These arrows group great. Even for an old hacker like me, I got a couple of 3" groups at 50 yards and a 4" at 60.

So if the sight was corrected so that both arrows were sighted in dead center at 20, the difference at 40 and 50 yards might be a little more than an inch. I haven't chronoed the FMJ's, but I'm guessing they are going about 8 or 9 fps slower than the 261 fps ST Axis. How many more months until archery elk season . . . .
