Red said it all, its to bad we might loss the 7mmwsm, as ever one has 270 imbeaded in there mines, from what Jack Oconnor wrote but if you read everything he wrote he did say the 7mm was a better bullet. I see the 7mmwsw doing quite well at long range shooting at benchrest and I believe it holds some records, I have never seen a a 270 at benchrest or hold any records. Go to Lost River Bullets and look up what a fellow shot with 7mm, 18' group at 2000 yards, pretty awsome.
