Excellent write-up & pictures Neale - thanks a huge amount.
The bullets look to be winners' all the way around.
I do like the looks of the bullet - all the ay around.

Well done!

Too bad you can't get BLC2 there. It's an incredible powder in the 9.3x62 - and .375/06IMP - it's capacity double in a 3/8" bore. I use it and H4895 in both ctgs. with all bullet weights.

Of course, there are no flies on 2,480 to 2,540fps with your loads and 270's.
