The throat in my rifle just won't handle the Bergers anymore but I loaded some 150 Ballistic tips yesterday at 68, 69 and 70 gr of Retumbo and accuracy was very good I had three groups that went about .750 and all at the same POI @ 100yrd. Couldn't run them over the crony due to wind and snow but I loaded a more extensive ladder test of 5 shots each at 69, 70 and 71 gr of Retumbo, this I'll shoot at 600yrd over the crony.
