Treb, I used a Merkel 141 in 9.3x74. The 1st shot was at 197yds off of shooting sticks It was a hit but he took off running. I came off the sticks and fired again. I drew feathers but he did not break stride. I cracked the gun reloaded swung through and dropped him at 325yds. Ostrich can soak up alot of lead, a friend hit on 4 times with an 30-06 before it came down. Not much of a breast but man do they have drum sticks!!
