ALSO...im curious to know what other 22-250 users are loading & what velocities you are getting...?
The charges listed are the highest tested, & so far no signs of pressure that i can tell...
All at 100m.
The brass was all formed & neck sized prior to these shots, & all rounds were seated at .010" off the lands
Ive only chrono'd the zmax loads & not happy with the velocities--the 36gr load with 50gr Zmax is only reading 3490-3500fps, which probably means the 55gr SIE GK with 35.5gr/2208 is probably only doing hot 223 velocities...im not sure what to expect as a norm, but i intend to check that against a different chrono to see if my magneto is a bit crook.
(This is the rifle i was getting some double grouping with--i pulled it out of the stock & replaced it with an extra 5in/lbs on the front screw & it appears to have fixed the problem--touch wood...! not one double group out of nearly 40 rounds )
Anyway, any thoughts on where you would further proceed appreciated...
Thanks.

I can't work out what "c.o.l -24.06" refers to, is it a typo?.

SCJ429 wrote:That is a great result especially with the Howa, I have not seen one that could shoot in the .3s. You must have a Wednesday barrel. Sako and Tikka barrels have really set the standard with their barrels so it is not surprising they can perform even with average quality brass.

I have an accuracy load of 36.5gr of AR2208 with a 55gr Sierra Gameking (Super roo), however, the velocity as tested with a Magnetospeed is only 3455 fps. The ADI load data has the max load of 36gr as 3730 fps with the same bullet.
What is going on here? ADI manual unrealistic? or Magneto inaccurate?
Can anybody provide any answers?
