Re: 6.5/284 Brass
I have and have used both Norma and Lapua in one of my fagmags. The external dims are almost identical. The main difference between the two was Norma was softer and I lost pockets much faster. The lapua looks better and has tighter pockets.
I think the Norma MAY have shot just a tic better, but not enough for me to spend the extra money for brass that lasted half as long.
As far as a chamber,, I had one with SAMMI MAX. and got 7 firing out of Lapua before loosing any to neck splits. That's with a .301" throat. A loaded round will measure about .293". I had that one rechambered and my new throats are .298", and I hope to get 10 per case. I don't anneal my cases either, and with the Lapua being heavily annealed from the factory, I think that may help with the case life.
Standard match reamers or 6.5x284WIN are built off necked down 284win brass and have throats in the .300 to .301" range, with bodies at .501". The 6.5x284 Norma match reamers usually have throats in the .297 to .298" range and bodies ranging from .498" to .501" depending on the manufacturer. My latest chamber has a .498" body and a .298" throat and it chambers virgin brass smooth as silk. It has a 2.5 degree leade which may not work out well,, but I'm willing to give it a try [img]images/icons/smile.gif[/img]
I'd ask him who's reamer he plans on using and get a drawing. To tight for the field is no good, but for target shooting, you'll get better brass life and possibly better MV with less powder and stress on the case.
