Re: 1000yd wind zero

for long/short range zeroes,it also helps if the axis of the bore, mounts and scope align in the vertical plane.

rod the possible insulating characteristics of the bonding medium between the block and barrel with bedded/glued in barrels was a consideration. i agree that if the bonding gap is thick that it would be a problem, but as i have around .0015" max loctite thickness, i am confident that any heat build ...

brad the rifle in the photo in the other thread is the 7mm kreiger which i have mentioned to you previously. due to it's less than expected accuracy after 500 rounds of wasted time effort, $$ and frustration, it is now a "club gun". the 6mm kreiger ordered and received at the same time in an identic...

FWIW
in my 308, (tobler 30" barrel)- more than 45/08 lapua cases /155projectiles or 46/08 w-w cases/155 projectiles leads to excessive pressure and difficult extraction/chambering within 2-3 loadings.
however i realise that in other rifles these loads are OK pressure wise!
