Good read their, Chas1. Thanks
I hear you and agree 100%. But we had been quite a bit higher with this load during development. We reduced it for accuracy as the sweet spot was not at max. I will take accuracy over velocity any day. So I felt we were in a safe spot but cautioned him to fire one, to check zero and watch for bolt lift or shiney spot on the case heads. He says that is all good. I will make sure before any more are fired.
This could very well be pressure and if so , bullets will be pulled and charge reduced.
