Anybody able to school me on the 7mm Blaser Mag cartridge? Looks like a well balanced round, not too overbore, enough capacity to drive 180's at good speeds. What's reamer, brass, die availability like?

I have built a few now, goes great, punches well above its weight, only just behind the 28 Nosler with around 10 grains less powder.Quote:

I have 6.5-7mm Blaser & 7mm Blaser reamers :)
Greg,
Do you reckon a 22" barrel length would compromise velocity too much or better served with a 26" + length?
There is always a compromise but my 24" test rifle went very well with the right powder, so 22 might be surprising.Quote:

I need to section the barrel to see if it has the same issue as my Carbon one from the same local manufacturer.....
Blackwatch might have some info on one....
I have the .300 Blaser built on a Ruger M77, pops 180g AB down range at a smidge over 3000fps from a 25" barrel, not a hot load but very accurate with 3 rnds fitting into what looks like 2 holes...
As A side it's for sale as I don't get to use it, have the dies new brass, used brass and load info, PM me if you like to know more @LJP
