One other point that I forgot to mention... because of the cupped base in a Gold Dot/Deep Curl, the only way that base can function correctly is with a fairly stout charge of powder. I am not sure that 90 grains or even 100 grains of GOEX is going to provide that extra stabilty that that base can provide. A flat based bullet like a XTP on the other hand can work well at the lower velocities...
Many moons ago RW wrote a big blog about the only bullets that will shoot accurately from a ML over and over again are flat based bullets.
So that also gives Muley little more creedance when he says try some BH that might turn you Speer bullets around into a more accurate class. I do not really want say to many positive things about you know who... Just makes him that more unbending...
