[QUOTE="EXPRESS, post: 1254914, member: 1441"] In the past I've used CEBs with good results. I haven't found them to be the most accurate in my rifles, but sub MOA and some loads .5MOA. Recently I picked up some 150 grain MTH in.308 cal to try in .300 win mag. This particular rifle has a 1:10 twist Shilen Select match grade barrel that seems to prefer lighter bullets (it shoots 168SMKs .25MOA). And it's not fussy about what you need to do to make it shoot. But with these bullets I ran in to some problems from the get go. I have found the CEBs to reach high(er) velocities with relatively low loads, but in this case, I was at high pressure from my starting loads, and moderate velocities, although still fairly high. My method is a ladder/OCW hybrid, so in two occasions, with .2 grain increments in powder I was getting progressively more severe ejector marks and flatter primers with the first three shots. The bolt lift was still easy, but, what worries me was that with just .2 grains more powder in each case I was able to see the increase in the ejector marks and the primers go from cratered to flattened to totally flat, as the string progressed. This has happened with two powders now, VV N165 and VV N160. Also, the accuracy is just terrible, I'm talking 3MOA with both trials. Next I might try seating close to the lands, to begin with I loaded them so the seal tite belt was just showing out of the case mouth as per their recommendation. Pulling bullets is getting old, and I don't reuse these ones for load development, just trajectory validation/chronographing once they have been pulled, so it's expensive and annying. Anyone else experience problems like this? [/QUOTE]
