, I was told its going to be smaller than the 338 case by Jimmy S. that water capisity is 101 for the 30 and 106 for the 338, does this sound like a basic neck down or a smaller and shorter case. Reason is Chris at longshot has reamers for the 30-338 norma wildcat and thats what I am leaning toward.
Here is a picture of the new 300 Jazz AKA.300-338 Norma improved by SSG. and a few test results.
The testing for the 300 Jazz was done with the list of components below
Phoenix machine action
Brux #5 contour, 9.5 twist- 28” barrel with one of my small x-treme “V” port brakes.
McMillan A-5 stock
I’ve only fired approx. 40 rounds through this so far. I worked up to 3200FPS with 201 JLK’s over the crony then did an accuracy test at 300yds. 3-shot went .750 and at 753 yd. 3-shot groups went approx 2.250.
Conditions were approx 5-7 mph winds and temps were around 15 degrees. I will be posting more pix with rifle and target in a few weeks.
