Why spend all that money? You can buy a 700 remington 338 ultramag. Same performance as the 338-300 ultramag or edge you mentioned. If you want to go top end then you can buy a Weatherby Accumark in 338-378 and gain about 200 fps over the ultramag case. Cabelas in Billings has some like new accumarks in 338-378 that can be bought for $1200-$1300. That would be your best buy.
