I had a few accuracy issues with my Remington 700 LVSF in .17Rem (1:9 twist) when I initially loaded some 25grn V-Maxes at the SAMMI standard COAL of 2.150". These initally produced very poor groups of around 11/2 - 2" at 100yds, similar to the factory ammo that was given to me with the rifle. I changed to 25grn Berger Varmint Match, same COAL and things dramatically improved. I am assuming that the V-Maxes were seated much deeper in the case due to the Ballistic Tip and that this was the reason for the poor accuracy due to too big a jump to the lands?
I am intending on accurately measuring the distance to the lands for my rifle and have an OAL gauge on order, but am interested to know what distance from the lands I should initially load to and then what increments to move back by? I'm guessing that I might actually get several very different recommendations regarding this!
There is another thread currently running regarding the myth of running with a small gap to the lands, but I would be really interested to know (particularly from any other .17Rem owners) where they think I should start please.
