I had a 30-06 that was not shooting very well.Sent it back to Remington for warranty repairs.After five months of waiting,I got it back.They replaced the barrel and the receiver.It shot a little better,but was about an 1 1/2" gun.I decided to send it to JES and rebore it to a 338-06.It shoots purty dang good now.200gr Nosler Ballistic Tips and Accubond are what I shoot in it.I can easily get 2800fps with several powders.210gr Partitions run around 2700fps. I think it will make quite a thumper.It cost me $250 for the rebore job with return shipping.I went with the five groove on mine.There and back was only two weeks.If you call,leave a message and Jesse will call you back.Here's some of my groups.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
