20BR barrel life.

[GeoffSeymour]

Can anybody advise me on the likely accurate life of a 1 in 9 twist barrel on a 20BR,does anybody have any experiance of life expectancy differences between barrels made from Chrom Moly and Stainless Steel.

Loads are likely to be in the region of 31.0gr of Vit N150.

Thanks for your help.

Geoff

No one got any idea then?. Seems odd.

I recon 800-1000 rounds from my own reserch providing I dont cook it.
