Is it possible Make 7mm wsm cartriges from 270 or300 wsm cartriges

Yup - either way. (cartridge CASES that is). Most opt for the easier 'neck-up' route but it depends on your chamber.

Thanks for the reply. Next question is there any problem bringing cartrige cases in to the UK from the USA or match non expanding bullet heads

In principle no problems at all however I have known turned solids be stopped by the Customs when they arrive.

I have heard that there is no problem with brand-new brass but customs don't like fired brass.

None of my business - but if you are building a 7mmWSM you'll want good brass and that ain't American so may not be much saving in buying say European Norma brass in the USA.

Vince.
The issue with fired brass would appear to be 'One member of the BA staff at Denver' she retired in November, so this issue should have now gone! ;-)

I have read Winchester brass is ok if sorted. Plus there is a huge difference In price. Norma about £170 per 100. Winchester with the exchange about £25 for 50
