Well I threw the new tuner from Aaron Hipp on to my 30" barreled 300 norma improved. It screws right over the existing muzzle threads and then you screw your suppressor or brake back over the threads. I Did a ladder test at 580 yds w N570 and 230 gr bergers. 88.3 gr of N570 looked to be in the middle of the node. Loaded 3 rounds up and it shot 1.7" at 580 which was .279 moa. Figured that was good enough and started twisting the tuner. I would adjust the windage half moa after every setting so they wouldn't all stack up on each other. After some tweaking I found the tuner setting. The first two shots were pretty much touching at 580 yds. I didn't let the barrel cool and grabbed the last round in the box and sent it down range as fast as I could. Ended up measuring .989"/.162 moa at 580 yds. Had .608"/.100 moa vertical. 230 gr berger at 3095 fps. Not a hot load in the 30" barrel. Definitely happy with this setup. The big TBAC SR 338 suppressor is awesome. Only problem is the norma improved heats it up really quick LOL.

Ill do some fine tuning on the tuner to see how wide the window is. But this definitely made load development easier. Load up a bunch of rounds at the same seating depth and tweak the tuner.
The range setup is perfect for load testing as its only 50 yds from the shop. The timber blocks the wind almost to the target when it comes from the west. Winds were almost non existent this morning and zero mirage. the kestral got up to 2mph winds. most of the time the fan didnt even move. The dot in my 10-50x kahles sits perfectly inside the tiny 1/2" square at 580 yds. I can guarantee my crosshairs are perfect everytime I pull the trigger. I put the astro turf up there so the bipod can dig into something.
Modular evolution with spikes keeps it on target. I can watch the bullet go down to the target even at 50x.

I have some rifles instock ready to ship. Im doing a package deal also where optics are mounted etc and knocking $500 off. This special won't last long. NF NX8 4-32, Kahles, Zero compromise optics are available for the package deal.

Were you shooting the 230 otm or 230 hybrid target?

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
