Just trying to see where it falls in line with other brass I work with. I have some Lapua Brass coming. I'm trying to shrink groups but more so to get ES and SD down more. I'll anneal them then neck down to 6.5-06 and turn necks to .0014 and see what happens.

What is the approximate case weight for 30-06 Lapua Brass?

191.32 grain avg, 1.61 grain ES for my last batch.
ETA: and at distances of up to 500 yards, Starline at 190.6 grains avg., with ES 2.8 grains, shot to the exact same point with the same group and speed stats.

Case weight doesn't mean anything. Case capacity is more important, they do not correlate very well because who know where the extra or less brass is.

Thanks. My Winchester 270 brass loads processed to 6.5-06 should be fairly close. They average about 186 grains unprimed. Remington 30-06 processed to 6.5 weigh around 193 unprimed. Hornady is around 179 grains and takes .5+ more grains of powder vs Winchester to reach same speeds.
I won't be able to compare capacity apples for apples until I process and fire some of the Lapua. I have fireformed 6.5-06 capacities for Hornady, Remington, and Winchester at the moment. While case weight doesn't give me a lot. The Hornady cases are at 179 grains are my lightest and require .5 plus more grains of powder to match the speed of my 186 grain case weight Winchester loads. With the heaviest cases being Remington at 193 grains presently, I have to drop .4 grains to match the speed of my Winchester loads. Once I have the Lapua I'll have weight and H20 capacity so I can see where they fit.
Compare dia at the web, get ready for a shock. Lapua runs .004 larger than Winchester, this can cause a problem with some chambers.

Thank you all for all the responses. I'll get some H2O capacities on them in #30-06. And then get case weight and H20 capacities once I prep and turn necks for it for my 6.5-06 And post them.

What do you plug the flash hole with when checking H20 capacities?
I just use a shot primer.

They make primer plugs for that. I believe 21st Cent has them. If now look around. I have some, but can't recall presently who makes them.
Overall case weight of the case maybe an inaccurate way to compare what you have.
Internal volume would be more accurate and yield more consistent down range performance.
This what I have found for my 06 cases internal capacities.
Winchester 30-06- 67.8
Winchester 30-06 AI - 72.3
LC 30-06 - 67.0
LC 30-06 AI- 71.4
Remington 30-06 AI - 71.3
Frontier 30-06 AI - 71.8
These are the empty case weights.
Frontier- 186.4
Win - 188
Remington - 202.1
LC - 194.3
Case weight does not give you an accurate information regarding actual internal volumes. The weight is often in different areas on different brands.

I realize there isn't a hard and fast correlation on case weight alone. I just wanted case weight to see where they fell in line with my other cases. I have some Lapua brass coming and intend to get H2O cap once they arrive and I convert them over to 6.5-06.
