I have made up my mind to pursue building a 6BR Norma rifle for 100 yd – 300 yd informal bench shooting. The next step is to determine the appropriate rate of twist and what I plan to shoot.

Based on what I have read and advice I have received, I’m thinking a 12 twist barrel for shooting 60gr – 80gr bullets at these shorter distances.

I haven't checked all sources yet but it looks like a 12 twist barrel is probably going to require a long lead time order. On the other hand, 8 twist barrels are in stock and available.

Is the 8 twist versatile enough to shoot the lighter bullets at short range or would you recommend that I hold out for the slower twist?
