6x45 load data

[mapper]

I didn't put it there, just found it.
Max loads in the 6x45 are midrange in the 6 mongoose as the mongoose has a little more capacity.
So the 6x45 is a good place to start as well as the other 6 mongoose data I have.

The 6x45 is just a 223/5.56 case necked up to 6 mm/243, really simple 1 pass through the size die to form.

The mongoose has to be formed from 5.56/223 and have shoulder setback, 40 degree shoulder and trimmed.
If in cases other than lc, ( lapua for sure) necks have to be turned, then brass fireformed, so it is more work on the case than 6x45.

But that said, I have a fair enough supply of fire formed brass to start working with in the mongoose.
I'd like to work up a 55,75,87,105 gr bullet load it likes.
The 105's won't fit in a ar mag though. Single feed or bolt gun. I haven't tried them yet to see if the controlled round feed bolt gun will play well with them.

Pretty standard powders for it though,(mongoose)
Benchmark, h-335, to cfe 223, blc-2 and varget speed wise.

I forgot I posted this before..
