Need UPS for FX120i

Do you know exactly what it is and how it works?
Per the manual:

Zero tracking ( trc )
This function tracks zero point drift caused by changes in the environment and stabilizes the zero
point. When the weight data is only a few digits, turn the function off for accurate weighing.
Note
Digit, when used for the FX-i series balance, indicates a unit of minimum weighing value.

trc 0
trc 1
trc 2
trc 3
The tracking function is not used. Used for weighing a very light sample.
The tracking function is used. Normal zero tracking.
The tracking function is used. Strong zero tracking.
The tracking function is used. Very strong zero tracking.

.223 Rifle Build

Since the OP wants a shorter lift, he can look at anything from a Tikka, to a 75* impact, to a Terminus, or even a Solus, depending on what he wanted.

I'm less of a fan on CF wrapped barrels if this is going to be a trainer/range toy. If hunting, that is a completely different answer and CF is a great option.

I like the 1:8 twist for everything up to about the 80gr range. 1:7 is going to start to benefit you more once you get over that. The 1:7 isn't going to hurt you either if you shoot bullets lighter than 68/69gr either...so that would be my choice (again).

For anything 80gr and below, the .223 Wylde chambering has enough freebore (.062, which will get you out to 2.4xx" OAL). If you are planning on running mostly 80-90gr, I'd probably look at something with at least .100, if not the ISSF at .169. I think (don't know) that some dedicated F-T/R guys might even run more freebore than that.

My .223 experience in a "custom" bolt gun is a trued 700, with a 1:7 Krieger Heavy Varmint at 26". It has a .223 Wylde chamber and really is boringly half-minute consistent with all of the bullets in the 68/69 - 77gr range that I've tried. I love it.

.223 - 5.56

Screwing around with 85.5 Hybrids in a new 223 bolt gun build with .183 free bore, 29.5” Proof competition 7 twist.

Lapua, 205M 24.4 H4895 .015 off
COAL 2.575
CBTO 2.034
2909 AV ES 40 SD 13.4

These are the 50th thru 55th shot on this barrel. Needs more break in….ES sucks

Tried some 90VLDs (right) but they were really underwhelming at this point.

Had success with the 85.5 Hybrids going 2950ish in my 6.5 twist 224V bolt gun.

Trying something stupid and futile for Range 4 Quantico.

M40A3 badger bm and MST-100

The guy who would be the most help here is @USMCSGT0331 .

From my EXTREMELY basic knowledge; I believe that the Unertl 10x were put on some of the first A3s, but those might also have had the DD Ross bottom metal too during that time frame. From memory, I also don't think that the S&B hit the rifles until around 2003, and then you had some Premier scopes on there too for quite a while.

There were a lot more variations of parts and optics scrounged and put together for the Corps than one might initially think until they start venturing down that rabbit hole mentioned above.

Bartlein Barrels Update

As already mentioned, just about every good barrel vendor has a good stock of Bartlein barrels. What our esteemed self-proclaimed expert is saying is that every individual who has a wild hair and orders a custom barrel directly from Bartlein should get special preference over the vendors and smiths who order barrels by the crate load. Sounds about right for the “me first” crowd… 🙄
