I know the Bar-Sto has a tighter chamber than the sig barrel but does the Bar-Sto have more case support in the feed ramp area ?

I was not very impressed with accuracy of the stock 40 barrel in my 229 SAS. I replaced it with a semi drop in Bar-Sto and it made a HUGE difference for the better.
Regarding case support, the factory Sig 40 barrel has excellent case support and is a non-issue.

A case fired in a Bar-Sto before sizing will fit in a sig chamber but a case fired in a sig chamber will not fit in a Bar-Sto chamber before sizing. That tells me the Bar-Sto is a tighter chamber. I called Bar-Sto today and they said yes there barrel does have more chamber support.
It is a non issue to you but have you blow an extractor with a sig barrel. A tighter chamber will give more support and work the brass less. Sure I could back the load down but the Bar-Sto handles it with no problems. The sizing die works the brass very little because the chamber is so tight. So you see I answered my own question with a call to Bar-Sto this mourning,

Thanks,Keith

People said I'm stupid for firing a max load in a case i did not know how many times it had been fired. OK lets say there right . So I did this I took a once fired case or a least they were bought as once fired. I loaded 12 plus grains behind a 135 Nosler JHP I say plus because I used a powder measure and 5 of the 10 loaded rounds were 12.3 grains. No big deal right only I loaded the SAME case 10 times to see if it was a case problem. The case held up fine not even a loose primer pocket. I would not do that with a SIG barrel. A case fired in a SIG barrel will not fit in a Bar-Sto barrel until it is sized. The better chamber support from the Bar-Sto barrel let me keep all my fingers and I did not need any Spare parts for me or the gun. I am thinking of selling some SIG barrels to replace them with Bar-Sto barrels I have 9 I could sell.
