Re: 338 win to edge
Your 338 winchester will kill elk at 1000 yards and I wouldn't mess with it. The 338 winchester is an excellent cartridge. The edge is one of the names later given to the 338-300 RUM I started doing in 1999. I did several on Ruger #1's and it is an easy convert. In your 26" barrel you will gain on average 250-300 fps over the 338 winchester. In other words with 300 grainers you will go from around 2450-2500 to 2750 fps. 250 grain you will go from 2750 or so to 3000+ fps. The 225's you will go from 2900 to 3250 or so fps. Hope that helps. If you do a good job with the rechamber you should not lose any accuracy. You would be better to go with the 338 RUM and stay with a factory cartridge. Same performance with no fuss reloading. After extreme testing I quit fooling with the 338-300 RUM in 2001 when the 338 RUM came out. Hope this helps.
Predictions are difficult, especially when they involve the future
