7-08 ackley speed?

[wildchild]

Just for snits and wiggles what kinda velocity would one expect out of 26 ish long barrel with 162 or 168 bullets from this case? Also any experience with this round with the small rifle primer pockets?

Wild child - i can not be specific re the 160 weights, but this may help.

I have just completed a 7-08AI on 700 trued, 24" 9xtwist fluted Hart done by Bobby Hart. Water capacity increased by 7% and velocity went up almost exactly 7% from multipul stated loadings for std case

mine shoots the following:
R/P cases 9 1/2 primers
H414 49.2 GR
140 Nos BT and SIerra 140SBT - .010 jump
Cases sized redding dies .002 bump
3025fps
.350" groups common at 100

This load in my chamber shows modest pressure, and no primer exprusion, flattening or pocket loosing, Be sureto work up slowly as your rifle will not be the same as mine.

I find that the% water increase works very well when gradually increasing powder to about the same - resulting in a fps increase by about the same % reguardless of bullet weight - i have a number of AI's and all seem to respect this method.
