Guys, I need a little help on which direction to head with this load. I'm shooting a Rem 700 ADL in .270 win. I have a load worked up using 130g SST's and 61g of H4831sc and WLR primers. Bullet is seated 20 thou off the lands and I'm getting groups of three under .5". Why change right? I want to use a 130 Speer Grand Slam as well. My first tests were with this bullet and H4831sc using an OCW method. Group averages were 1.5" at 100yds. Disappointed, I tried H4350. The sighters in my OCW test were all three touching while every group after was 1.5"-2". This was all done at 100yds from a bench and all of the bullets were seated to the published depths. Any suggestions on what direction to go from here?
