blown primers
Blown primers are not necessarily a sign of high pressure. This may be the case with your load... especially if the primers of not flattened. Another thing to try is change the brand of primers that you are using. If I remember correctly CCI small rifle mag. primers have the thickest cup. I have an article that I will dig and post the link to.
H110 and W296 are pretty much the same powders. W296 tends to run a bit slower. There can also be a bit of variation between powder lots
