[QUOTE="brentc, post: 619569, member: 16938"] I'm experimenting with the Berger 180 with Retumbo. I am using a standard CCI 200 seated to just touch the lands at a coal of 3.425. I loaded up in .4 grain increments from 68.0 to 70.0 grains and saw an increase of 17 fps per increment. I got it up to 2950 with a decent ES and good accuracy. I hit a one hole accuracy node right around 68.8 grains and 2900 fps. I was able to push to 70 grains at 2950 fps without pressure signs. I expect to hit the upper node at 70.4 grains at 2965 fps. All loads were sub MOA in my 28" pac nor and .25 MOA at the accuracy node. ES was decent. Some charges were single digit, and others were around 20. [/QUOTE]
