The Creedmoor Sports factory loads with the 167 Scenar in Lapua brass (the ones SU35 mentioned early in this thread), are averaging right at MOA in my rifle.
I took 165 NBTs to the range loaded over Big Game on Wednesday. OAL was mag limited at 2.85", which put them .090" off the lands. Fed 215 primers, Lapua brass.
I took 48, 49, and 50 grains. Ramshot's max is 51 so I will also try that, as groups shrunk as charges increased. Three-shot groups.

48gr - 2556 FPS, SD 17, 1.29"
49gr - 2579 FPS, SD 12, 1.86"
50gr - 2619 FPS, SD 2, 1.25"

This makes 51 grains look promising. Also, I need to try the same loads with the 165 NAB.
And d500inn's experience with the 150 grainers in the post above makes me want to try some of those. I had avoided them just because their lesser wind resistance but within reasonable ranges, the extra velocity could more than make up for the lower BC. And I bet I can get the 150 partition out a lot closer to the lands at the mag limited length. I'll measure that this morning and post the results.

Cheers,
Rex
