I have a Bellm 30-40 barrel and a Bullberry 300 savage and both of them are keepers and I feel very safe firing factory ammo and reasonable reloads in both. I think the 300 savage is actually a better contender round than the Krag for high velocity condom bullet shooting, but I really like the Krag for long heavy cast bullets. Both of these barrels are 4 narrow land barrels, things might be different with fat land factory barrels rechambered...I do have to admit though, I really do like the 30-30AI also!
regards,
