Does anyone have the perfect load worked up for the Berger 210 in their Sendero 300 RUM that they'd be willing to share? Would prefer to stay with the standard 3.60" COAL if possible so the factory magazine well will work.
I worked up a good load with the 210's in my Sendero with Retumbo, however the COAL was 3.865 just touching the lands. 93 gr, 3130 fps and about .5 to .75 MOA
Tried the 200 AB's as well and they were the least accurate in my rifle of the 5 bullet types I tried. About 1 MAO.
180 E-Tips were very good with fairly consistent sub .5 MOA groups.
Best were Cutting Edge 180's (C32).
Bergers can be quite sensitive to seating depth/jump. You might want to check out the Berger sticky in the Reloading forum....

Hope that helps
P.S. It obviously didn't fit into the mag but I was able to put one down with tip just above mag box for second shot follow up.
