“The 22 Creedmoor Project”

[huntnful]

Tested 4831SC yesterday evening.

Ladder test looking for pressure.
41- 3054
42- 3120
43- 3180
44- 3308 flat primer. Easy bolt lift.


Then shot a 10 shot group with 42.5gr.



Then did some positional testing on what mid-height position is the fastest and most comfortable for me to get into. I’ve settled on kneeling with left down, right knee up. I then shot a 5 shot group from that position at 420 yards.

Using what for rests while kneeling?

Using what for rests while kneeling?

A hatch 27” bipod. Extended about 3/4 of the way. Then the toe of the stock is resting on my right knee.

I don’t know anything about reloading, but why do you think there’s a larger increase in velocity from 43gr to 44gr than the rest of the increments?
