Re: To go Improved or not on 338 Lapua
Broz is right. Either one will kill anything as far as you can hit it. Back in the 90's when I did all the work on improving the lapua case the best we could do was about 150 fps by pushing the shoulder forward and using minimum taper. I would not AI the lapua. If i improved it the one i mentioned is best. Not worth the trouble and better off with the standard. One of the several problems you get into is ejection problems at times where the sloped lapua case is made to military specs for easy ejection.
Or an idea would be just get the 338 Lazzeroni if you want more performance. I don't remember what John calls that one but it will outperform either.
Predictions are difficult, especially when they involve the future
