Recently I got a case annealer from sassybrass.net. I had considered annealing before but couldn't see paying $500+ for an annealer. The one I bought was less expensive and seems to work well.
This, post annealing, is quite a bit better than what I got previously with Lake City Brass. Groups with this load had been in the 1.5 to 2 inch range.
This Lake City brass was not only annealed but had turned necks. It would appear that my work in neck turning didn't add much to accuracy.
And finally the load with the Lapua brass I had used before. Not much difference but then Lapua brass comes annealed from the factory.
So, it would appear that Lake City brass is equivalent to Lapua brass in the accuracy department as long as one goes to the trouble of annealing.
All brass, by the way, was at least once fired and had been full length resized prior to annealing.
The rifle actually shoots tighter groups (in the 0.6 range) with 42.5 grains of IMR 8208XBR at 100 yards with a muzzle velocity of 2,812 fps but a large extreme spread of 246 which would probably be a disadvantage at 400 yards. With 45.5 grains I get about 2,843 fps with a better extreme spread of 75 fps so I'll probably stick with 45.5 grains.
