Back about 15 years ago, I wanted to build a 338Mag that had more Umph than the 338WinMag. At that time I was into using the 8mmRemMag case for all of my projects. I built the 7mmSTW, I necked one to 30cal, Idid one in 375JRS and I was next planing to fill the gap with one necked to 338. Since than, I never finished the 338 project but I have a beautiful 26" barrel that is unchambered in that caliber. Since than there are many new Mags in that caliber but I do not want to, Change the bolt head size from the Belted Mag size and I do not want any more recoil than the belted magnums provide. The RUMs I read are quite brutal. Since than I also started shooting quite few 8x57 Mausers which I did not shoot at the time. So, If I just neck to something like the 338 Jerrett, I have another wildcat which I can't buy off the shelf ammo for or since I already have a plethora of 8mm reloading supplies, should I just stick to the 8mmRemMag which I did not even consider at the time when I ordered my barrel. It is easy to sell an unchamered barrel and just buy a new barrel and call it quits. The bullet size is only .015" and today there are quite a bit more bullet selections in 8mm than there were 15 years ago. What do you guys think. Obviously I will make up my own mind but would like to get some input to help me do so.
