6.8 Western brass made from 7 SAUM case performance?

[alpinewanderer]

This is an obscure topic I know, but I'm curious how your 7 SAUM-turned-6.8 Western cases have been performing over the long run. How do they compare to true 6.8 Western head-stamped brass when loading for accuracy? Is there a discernible difference in stats between your loads that use the "home brew 6.8 W-from-7 SAUM" cases vs. true 6.8 Western cases?

A couple of years ago some threads popped up on various forums about how to take 7 SAUM brass and run it through your 6.8 Western FL sizing die to create 6.8 Western cases (which continue to be hard to find). Having looked at the SAAMI specs for both cartridges, they are very close in dimensions. People commenting on the how-to threads seem to have had no issues but nobody really seems to have reported back on performance.

Have you tried it? How has it work out for you?

built a 30-6.8W right after the 6.8 prints became available and it has only shot Norma 7saum brass, on 12th reload and holding its own but getting tired. highly recommend using the false shoulder method of fire forming not the bullet jam method. never used any of the factory brass so have no side by side comparison.
i believe ADG is coming out with 6.8W brass soon, so might to check with them on production before committing to fire forming saum brass.

I think the only time it would be a discernable benefit is if you were limited to low quality brass for the chambering but could obtain and fireform higher quality brass. Otherwise, it probably isn't worth the work and components. As mentioned above, if ADG is coming out with 6.8W brass, I'd try to go that route.
