Thanks thats great info, I haven't measured my throat to see what distance my lands is.
I wonder if there is anyone around Oamaru who knows what they are doing that could measure my 223 for me?

its dead easy.....put the flat end on your cleaning rod.....put a projectile in a non sized case with just enough grip to hold it there,leave it long...chamber it by hand and push if t forwards till projectile is jammed into rifling...slip your cleaning rod down barrel and mark it at muzzle...take out the dummy round....slip rod back down untill it touches closed bolt face... that will tell you distance from rear of case/primer to tip of projectile...not hard to work it out from there....you can use a flat base projectile backwards too....doesnt give you any more info...... you know what your jam length is and work back from there....well fancy pants reloaders do...I on other hand just seat to mag length and are happy...

I'm not very clever with this sort of stuff
