I am working on a load for this on a Remington 700 w/26" krieger 8 twist barrel. I started using Hornady 105 Amax's using H4350 w/cci br2 primers but could not get the velocity I wanted. I was up to 40.5 grains of this powder but accuracy was better at 39.5 grains. I later worked with R17 w/wolf primers. I loaded up to 41.5 grains and am currently getting 2967 fps on my CED M2 chronograph. Accuarcy is pretty good with this load. Im not sure how much further I should push this load. I have no pressure signs yet. I measeure the OAL by the Ogive. In the rifle the OAL is 2.389 on the ogive to the lands. I loaded the rounds to 2.301 on the ogive. Should I change this length, Im still new to this reloading and if Im not doing it right, let me know, Thanks.
