Hello All,

400NE
Have you observed a barrel wall thickness threshold where OSR is more or less likely to occur ?
I have a CZ550 (.375 H&H), Ruger RSM (.416 Rigby) and Douglas barrelled Mark X (9.3x62).
I have both X and Mono solids from Barnes, The X's are the old type (no bands) and the Mono's are the round nose type (I believe they have bands, I will have to check).
I have done some limited load development, and have not observed any issues.
But now I am curious since OSR has been observed in bolt guns.
All of the above guns have pretty healty, meaty barrels.

Your thoughts would be appreciated.

This is not a hijack, just a redirect, since OSR is still the subject, just not in doubles.

Thanks
