Thought I would post a thread to introduce a new caliber.
The 300 JAZZ.
This rifle was built for me by SSG gunsmithing( Nathan Dagley ). All work was done by Nathan, except the digital camo on the stock was done by Travis Redell.
This caliber is based on the 338 Norma Mag necked down to 30 cal, with an improved shoulder. This project was started last July, when I looked at the 338 Norma, and liked what I saw in the cartridge. I thought at the time that the 338 reamer was proprietary, so I decided to neck it down to 30cal. Nathan and I agreed on a 30 degree shoulder for it, and Nate ordered the reamer. After pressure testing and load developement, I have 2 loads. One for the 210 gr Berger VLD and one for the 240gr SMK. One plus of this caliber is that you can seat the long 210gr Berger or the 240gr SMK with the BT at the neck/ shoulder junction and it fits in a standard size magbox of 3.60"
With a 28" Brux barrel I am getting 3150 fps with the 210gr Bergers, and 2850 fps with the 240gr SMK. I am still using the same 20pcs of brass I started with and have 10-12 reloads on them and the primer pockets are still good. The 338 Norma brass seems to be top quality.
Nathan does excellent work, and this is an extremely accurate rifle, more accurate than I can do it justice.
Here are the listing of components:
-Phoenix action, SSG fluting and knob
-Manners GAT stock
-Seekins recoil lug/ keyed into Seekins 20 MOA rail
-HS Precision DMB
-SSG muzzlebreak. I love this break
- Nightforce 5.5x22-50 mm scope
