The 7 stw was all the rage and remington figured it out eventually, now we need Lapua and Norma to solidify it by making BRASS. Say a prayer, someone at Lapua and/or Norma hopefully will get the message. Right now there are 4 hot calibers it seems. 6mm, dasher,br,xc etc,, 260, by 284, x55, by 47, 280, stw, mag, wsm, then 300's, 338's etc. All we need is more quality brass. The 7 stw is interesting especially as a hunting round and maybe the best overall for the broadest variety of uses, even benchrest. I still believe we should send an occaisional email or letter, even hand written to Norma and Lapua to beg them to make brass.
On another note, I re-wrote my post without a negative tone and asked my gunsmith what he thought. He reamed it. I think 7stw is correct, my gunsmith used some form of tight reamer and the neck is tight. He was trying to make the gun really accurate but I think SAAMI safe, at least that's my interpretation right now. It is a real shooter. Lapua empty cases and commercial fireformed cases load fine, so it probably isn't unsafe, but has a "tight neck." I hope that's the answer anyway. In time, as the barrel wears, does the headspace change?
Does anyone buy go/no-go guages for their calibers as a tool to have on hand to check headspacing occaisionally. I'm thinking maybe I should for the different calibers I have?
