Re: OSR, Double Damage and Barnes' Response

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

I have a friend who has built several "super light" bolt guns in .308 based cases (i.e. .243, 7-08 etc). He uses an incredibly thin barrel that is fluted, length is 19"; these barrels are about as thin as he can go and keep them safe. To make up for the short barrel he uploads a bit to recover the lost velocity. He also uses Barnes TSXs. So far, I have heard of no issues with his barrels. It's one data point so take it for what its worth.
